When a floating structure is made with concrete, concrete shear key with saw-teeth shape is often used to carry shear force. Match casting for the shear key and precise construction on a sea are very important for making separated two pontoons as one body but those are not easy work and may increase construction time and cost. To solve this problem, one-way shear key is studied in this paper for a connected part where there is some difference between upward and downward shear force. It has only one inclined plane and can resist shear force in one direction. Big shear force is resisted by concrete which forms an inclined plane and small shear force is resisted by steel bar. This system can reduce manufacturing cost of individual pontoon and construction time and cost for constructing a floating structure on a sea. In this paper, the feasibility study about one-way shear key system is performed by comparing with design example. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=connection" title="connection">connection</a>, <a href="https://publications.waset.org/abstracts/search?q=floating%20container%20terminal" title=" floating container terminal"> floating container terminal</a>, <a href="https://publications.waset.org/abstracts/search?q=pontoon" title=" pontoon"> pontoon</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-stressing" title=" pre-stressing"> pre-stressing</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20key" title=" shear key"> shear key</a> </p> <a href="https://publications.waset.org/abstracts/6234/study-on-connecting-method-of-box-pontoons" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6234.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">318</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3388</span> Seismic Base Shear Force Depending on Building Fundamental Period and Site Conditions: Deterministic Formulation and Probabilistic Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Dorbani">S.

These structures are erected at different epicentral distances. Using the Boumerdes, Algeria (2003) earthquake data, we focused primarily on the establishment of the deterministic formulation linking the base shear force to two parameters: The first one is the fundamental period that represents the numerical fingerprint of the structure, and the second one is the epicentral distance used to represent the impact of the earthquake on this force. In a second step, with a view to highlight the effect of uncertainty in these parameters on the analyzed response, these parameters are modeled as random variables with a log-normal distribution. The variability of the coefficients of variation of the chosen uncertain parameters, on the statistics on the seismic base shear force, showed that the effect of uncertainty on fundamental period on this force statistics is low compared to the epicentral distance uncertainty influence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=base%20shear%20force" title="base shear force">base shear force</a>, <a href="https://publications.waset.org/abstracts/search?q=fundamental%20period" title=" fundamental period"> fundamental period</a>, <a href="https://publications.waset.org/abstracts/search?q=epicentral%20distance" title=" epicentral distance"> epicentral distance</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty" title=" uncertainty"> uncertainty</a>, <a href="https://publications.waset.org/abstracts/search?q=lognormal%20variables" title=" lognormal variables"> lognormal variables</a>, <a href="https://publications.waset.org/abstracts/search?q=statistics" title=" statistics"> statistics</a> </p> <a href="https://publications.waset.org/abstracts/59431/seismic-base-shear-force-depending-on-building-fundamental-period-and-site-conditions-deterministic-formulation-and-probabilistic-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59431.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">320</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3387</span> An Efficient Approach for Shear Behavior Definition of Plant Stalk </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20R.%20Kamandar">M.

Massah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The information of the impact cutting behavior of plants stalk plays an important role in the design and fabrication of plants cutting equipment. It is difficult to investigate a theoretical method for defining cutting properties of plants stalks because the cutting process is complex. Thus, it is necessary to set up an experimental approach to determine cutting parameters for a single stalk. To measure the shear force, shear energy and shear strength of plant stalk, a special impact cutting tester was fabricated. It was similar to an Izod impact cutting tester for metals but a cutting blade and data acquisition system were attached to the end of pendulum's arm. The apparatus was included four strain gages and a digital indicator to show the real-time cutting force of plant stalk. To measure the shear force and also testing the apparatus, two plants’ stalks, like buxus and privet, were selected. The samples (buxus and privet stalks) were cut under impact cutting process at four loading rates 1, 2, 3 and 4 m.s<sup>-1</sup> and three internodes fifth, tenth and fifteenth by the apparatus. At buxus cutting analysis: the minimum value of cutting energy was obtained at fifth internode and loading rate 4 m.s<sup>-1</sup> and the maximum value of shear energy was obtained at fifteenth internode and loading rate 1 m.s<sup>-1</sup>. At privet cutting analysis: the minimum value of shear consumption energy was obtained at fifth internode and loading rate: 4 m.s<sup>-1</sup> and the maximum value of shear energy was obtained at fifteenth internode and loading rate: 1 m.s<sup>-1</sup>. The statistical analysis at both plants showed that the increase of impact cutting speed would decrease the shear consumption energy and shear strength. In two scenarios, the results showed that with increase the cutting speed, shear force would decrease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Buxus" title="Buxus">Buxus</a>, <a href="https://publications.waset.org/abstracts/search?q=Privet" title=" Privet"> Privet</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20cutting" title=" impact cutting"> impact cutting</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20energy" title=" shear energy"> shear energy</a> </p> <a href="https://publications.waset.org/abstracts/109634/an-efficient-approach-for-shear-behavior-definition-of-plant-stalk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109634.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">125</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3386</span> Sound Exposure Effects towards Ross Broilers Growth Rate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rashidah%20Ghazali">Rashidah Ghazali</a>, <a href="https://publications.waset.org/abstracts/search?q=Herlina%20Abdul%20Rahim"> Herlina Abdul Rahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mashitah%20Shikh%20Maidin"> Mashitah Shikh Maidin</a>, <a href="https://publications.waset.org/abstracts/search?q=Shafishuhaza%20Sahlan"> Shafishuhaza Sahlan</a>, <a href="https://publications.waset.org/abstracts/search?q=Noramli%20Abdul%20Razak"> Noramli Abdul Razak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sound exposure effects have been investigated by broadcasting a group of broilers with sound of Quran verses (Group B) whereas the other group is the control broilers (Group C).

Twenty-seven broilers were randomly selected from each group on Day 24 and weight measurement was carried out every week till the harvest day (Day 39). Group B showed a higher mean weight on Day 24 (1.441±0.013 kg) than Group C. Significant difference in the weight on Day 39 existed for Group B compared to Group C (p< 0.05). However, there was no significant (p> 0.05) difference of shear force in the same muscles (breast and drumstick raw meat) of both groups but the shear force of the breast meat for Group B and C broilers was lower (p < 0.05) than that of their drumstick meat. Thus, broadcasting the sound of Quran verses in the coop can be applied to improve the growth rate of broilers for producing better quality poultry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=broilers" title="broilers">broilers</a>, <a href="https://publications.waset.org/abstracts/search?q=sound" title=" sound"> sound</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20force" title=" shear force"> shear force</a>, <a href="https://publications.waset.org/abstracts/search?q=weight" title=" weight"> weight</a> </p> <a href="https://publications.waset.org/abstracts/15100/sound-exposure-effects-towards-ross-broilers-growth-rate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15100.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">418</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3385</span> Design of Reinforced Concrete (RC) Walls Considering Shear Amplification by Nonlinear Dynamic Behavior</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunghyun%20Kim">Sunghyun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong-Gun%20Park"> Hong-Gun Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the performance-based design (PBD), by using the nonlinear dynamic analysis (NDA), the actual performance of the structure is evaluated.

This shear amplifying effect causes repeated designs which make designer difficult to apply the PBD. Therefore, in this paper, factors which affect shear amplification were studied. For the 20-story wall model, the NDA was performed.

The yield strength of shear reinforcement and the compressive strength of concrete decreased the diagonal shear crack width of RC members for the same shear force because of the change of shear failure modes.

However, SWE is currently implemented using array probes. Price and volumes of these probes and their driving equipment prevent SWE from being used in wearable human-machine interfaces (HMI). Moreover, beamforming processing for array probes reduces the real-time performance. To achieve SWE by wearable HMIs, a customized three-element probe is adopted in this work, with one element for acoustic radiation force generation and the others for shear wave tracking. In-phase quadrature demodulation and 2D autocorrelation are adopted to estimate velocities of tissues on the sound beams of the latter two elements. Shear wave speeds are calculated by phase shift between the tissue velocities. Three agar phantoms with different elasticities were made by changing the weights of agar. Values of the shear elastic modulus of the phantoms were measured as 8.98, 23.06 and 36.74 kPa at a depth of 7.5 mm respectively. This work verifies the feasibility of measuring shear elastic modulus by wearable devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shear%20elastic%20modulus" title="shear elastic modulus">shear elastic modulus</a>, <a href="https://publications.waset.org/abstracts/search?q=skeletal%20muscle" title=" skeletal muscle"> skeletal muscle</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a>, <a href="https://publications.waset.org/abstracts/search?q=wearable%20human-machine%20interface" title=" wearable human-machine interface"> wearable human-machine interface</a> </p> <a href="https://publications.waset.org/abstracts/127469/achieving-shear-wave-elastography-by-a-three-element-probe-for-wearable-human-machine-interface" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127469.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3382</span> Study on the Impact of Size and Position of the Shear Field in Determining the Shear Modulus of Glulam Beam Using Photogrammetry Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Niaz%20Gharavi">Niaz Gharavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hexin%20Zhang"> Hexin Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The shear modulus of a timber beam can be determined using torsion test or shear field test method. The shear field test method is based on shear distortion measurement of the beam at the zone with the constant transverse load in the standardized four-point bending test. The current code of practice advises using two metallic arms act as an instrument to measure the diagonal displacement of the constructing square. The size and the position of the constructing square might influence the shear modulus determination. This study aimed to investigate the size and the position effect of the square in the shear field test method. A binocular stereo vision system has been employed to determine the 3D displacement of a grid of target points. Six glue laminated beams were produced and tested. Analysis of Variance (ANOVA) was performed on the acquired data to evaluate the significance of the size effect and the position effect of the square. The results have shown that the size of the square has a noticeable influence on the value of shear modulus, while, the position of the square within the area with the constant shear force does not affect the measured mean shear modulus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shear%20field%20test%20method" title="shear field test method">shear field test method</a>, <a href="https://publications.waset.org/abstracts/search?q=structural-sized%20test" title=" structural-sized test"> structural-sized test</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20modulus%20of%20Glulam%20beam" title=" shear modulus of Glulam beam"> shear modulus of Glulam beam</a>, <a href="https://publications.waset.org/abstracts/search?q=photogrammetry%20approach" title=" photogrammetry approach"> photogrammetry approach</a> </p> <a href="https://publications.waset.org/abstracts/90264/study-on-the-impact-of-size-and-position-of-the-shear-field-in-determining-the-shear-modulus-of-glulam-beam-using-photogrammetry-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90264.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">291</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3381</span> Optimum Structural Wall Distribution in Reinforced Concrete Buildings Subjected to Earthquake Excitations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nesreddine%20Djafar%20Henni">Nesreddine Djafar Henni</a>, <a href="https://publications.waset.org/abstracts/search?q=Akram%20Khelaifia"> Akram Khelaifia</a>, <a href="https://publications.waset.org/abstracts/search?q=Salah%20Guettala"> Salah Guettala</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Chebili"> Rachid Chebili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reinforced concrete shear walls and vertical plate-like elements play a pivotal role in efficiently managing a building's response to seismic forces. This study investigates how the performance of reinforced concrete buildings equipped with shear walls featuring different shear wall-to-frame stiffness ratios aligns with the requirements stipulated in the Algerian seismic code RPA99v2003, particularly in high-seismicity regions. Seven distinct 3D finite element models are developed and evaluated through nonlinear static analysis. Engineering Demand Parameters (EDPs) such as lateral displacement, inter-story drift ratio, shear force, and bending moment along the building height are analyzed. The findings reveal two predominant categories of induced responses: force-based and displacement-based EDPs. Furthermore, as the shear wall-to-frame ratio increases, there is a concurrent increase in force-based EDPs and a decrease in displacement-based ones. Examining the distribution of shear walls from both force and displacement perspectives, model G with the highest stiffness ratio, concentrating stiffness at the building's center, intensifies induced forces. This configuration necessitates additional reinforcements, leading to a conservative design approach. Conversely, model C, with the lowest stiffness ratio, distributes stiffness towards the periphery, resulting in minimized induced shear forces and bending moments, representing an optimal scenario with maximal performance and minimal strength requirements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dual%20RC%20buildings" title="dual RC buildings">dual RC buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=RC%20shear%20walls" title=" RC shear walls"> RC shear walls</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20nonlinear%20pushover%20analysis" title=" static nonlinear pushover analysis"> static nonlinear pushover analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20performance" title=" seismic performance"> seismic performance</a> </p> <a href="https://publications.waset.org/abstracts/182473/optimum-structural-wall-distribution-in-reinforced-concrete-buildings-subjected-to-earthquake-excitations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182473.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">56</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3380</span> Estimation of Damping Force of Double Ended Shear Mode Magnetorheological Damper Using Computational Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gurubasavaraju%20T.%20M.">Gurubasavaraju T.

The damping force could be estimated through computational analysis using finite element and computational fluid dynamics analysis. The double-ended damper operates without changing the total volume of fluid. In this paper, damping force of double ended damper under different magnetic field is computed. Initially, the magneto-statics analysis carried out to evaluate the magnetic flux density across the fluid flow gap. The respective change in the rheology of the MR fluid is computed by using the experimentally fitted polynomial equation of shear stress versus magnetic field plot of MR fluid. The obtained values are substituted in the Herschel Buckley model to express the non-Newtonian behavior of MR fluid. Later, using computational fluid dynamic (CFD) analysis damping characteristics in terms of force versus velocity and force versus displacement for the respective magnetic field is estimated. The purpose of the present approach is to characterize the preliminary designed MR damper before fabricating. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MR%20fluid" title="MR fluid">MR fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20ended%20MR%20damper" title=" double ended MR damper"> double ended MR damper</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=FEA" title=" FEA "> FEA </a> </p> <a href="https://publications.waset.org/abstracts/98450/estimation-of-damping-force-of-double-ended-shear-mode-magnetorheological-damper-using-computational-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98450.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">180</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3379</span> A Comparison between Shear Bond Strength of VMK Master Porcelain with Three Base-Metal Alloys (Ni-Cr-T3, Verabond, Super Cast) and One Noble Alloy (X-33) in Metal-Ceramic Restorations </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Neshati">Ammar Neshati</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Hamidi%20Shishavan"> Elham Hamidi Shishavan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Statement of Problem: The increase in the use of metal-ceramic restorations and a high prevalence of porcelain chipping entails introducing an alloy which is more compatible with porcelain and which causes a stronger bond between the two. This study is to compare shear bond strength of three base-metal alloys and one noble alloy with the common VMK Master Porcelain. Materials and Method: Three different groups of base-metal alloys (Ni-cr-T3, Super Cast, Verabond) and one group of noble alloy (x-33) were selected. The number of alloys in each group was 15. All the groups went through the casting process and change from wax pattern into metal disks. Then, VMK Master Porcelain was fired on each group. All the specimens were put in the UTM and a shear force was loaded until a fracture occurred. The fracture force was then recorded by the machine. The data was subjected to SPSS Version 16 and One-Way ANOVA was run to compare shear strength between the groups. Furthermore, the groups were compared two by two through running Tukey test. Results: The findings of this study revealed that shear bond strength of Ni-Cr-T3 alloy was higher than the three other alloys (94 Mpa or 330 N). Super Cast alloy had the second greatest shear bond strength (80. 87 Mpa or 283.87 N). Both Verabond (69.66 Mpa or 245 N) and x-33 alloys (66.53 Mpa or 234 N) took the third place. Conclusion: Ni-Cr-T3 with VMK Master Porcelain has the greatest shear bond strength. Therefore, the use of this low-cost alloy is recommended in metal-ceramic restorations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shear%20bond" title="shear bond">shear bond</a>, <a href="https://publications.waset.org/abstracts/search?q=base-metal%20alloy" title=" base-metal alloy"> base-metal alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=noble%20alloy" title=" noble alloy"> noble alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=porcelain" title=" porcelain"> porcelain</a> </p> <a href="https://publications.waset.org/abstracts/9916/a-comparison-between-shear-bond-strength-of-vmk-master-porcelain-with-three-base-metal-alloys-ni-cr-t3-verabond-super-cast-and-one-noble-alloy-x-33-in-metal-ceramic-restorations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9916.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">488</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3378</span> Ductility of Slab-Interior Column Connections Transferring Shear and Moment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omar%20M.%20Ben-Sasi">Omar M.

Tests to failure on six half-scale specimens were conducted for slab-interior column connections transferring shear force and unbalanced moment. The influences on connection ductility of four parameters; namely, the moment to shear force ratio, the ratio of column side length to slab effective depth, the aspect ratio of the column cross section, and the presence of four square openings located next to column corners were investigated. The study revealed marked effects of these parameters on connection ductility. Increasing the first and second parameters, were found to be in favor of increasing connection ductility, while the third and fourth parameters were found to have negative effects on the connection ductility. These findings should, hopefully, help in designing interior connections of flat slab structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ductility" title="ductility">ductility</a>, <a href="https://publications.waset.org/abstracts/search?q=flat%20slab" title=" flat slab"> flat slab</a>, <a href="https://publications.waset.org/abstracts/search?q=failure" title=" failure"> failure</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20force" title=" shear force"> shear force</a>, <a href="https://publications.waset.org/abstracts/search?q=moment" title=" moment"> moment</a>, <a href="https://publications.waset.org/abstracts/search?q=unbalanced%20moment" title=" unbalanced moment"> unbalanced moment</a>, <a href="https://publications.waset.org/abstracts/search?q=punching%20failure" title=" punching failure"> punching failure</a>, <a href="https://publications.waset.org/abstracts/search?q=connection" title=" connection"> connection</a>, <a href="https://publications.waset.org/abstracts/search?q=interior-column%20connection" title=" interior-column connection"> interior-column connection</a> </p> <a href="https://publications.waset.org/abstracts/8917/ductility-of-slab-interior-column-connections-transferring-shear-and-moment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8917.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">400</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3377</span> A Study on Performance-Based Design Analysis for Vertical Extension of Apartment Units</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Minsun%20Kim">Minsun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ki-Sun%20Choi"> Ki-Sun Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Jee%20Lee"> Hyun-Jee Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Young-Chan%20You"> Young-Chan You</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is no reinforcement example for the renovation of the vertical and horizontal extension to existing building structures which is a shear wall type in apartment units in Korea. Among these existing structures, the structures which are shear wall type are rare overseas, while Korea has many shear wall apartment units. Recently, in Korea, a few researchers are trying to confirm the possibility of the vertical extension in existing building with shear walls. This study evaluates the possibility of the renovation by applying performance-based seismic design to existing buildings with shear walls in the analysis phase of the structure. In addition, force-based seismic design, used by general structural engineers in Korea, is carried out to compare the amount of reinforcement of walls, which is a main component of wall structure. As a result, we suggest that performance-based design obtains more economical advantages than force-based seismic design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20for%20extension" title="design for extension">design for extension</a>, <a href="https://publications.waset.org/abstracts/search?q=performance-based%20design" title=" performance-based design"> performance-based design</a>, <a href="https://publications.waset.org/abstracts/search?q=remodeling" title=" remodeling"> remodeling</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20wall%20frame" title=" shear wall frame"> shear wall frame</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20analysis" title=" structural analysis"> structural analysis</a> </p> <a href="https://publications.waset.org/abstracts/79730/a-study-on-performance-based-design-analysis-for-vertical-extension-of-apartment-units" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79730.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">225</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3376</span> Triplet Shear Tests on Retrofitted Brickwork Masonry Walls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Berna%20Istegun">Berna Istegun</a>, <a href="https://publications.waset.org/abstracts/search?q=Erkan%20Celebi"> Erkan Celebi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of this experimental study is to assess the shear strength and the crack behavior of the triplets built of perforated brickwork masonry elements. In order to observe the influence of shear resistance and energy dissipating before and after retrofitting applications by using the reinforcing system, static-cyclic shear tests were employed in the structural mechanics laboratory of Sakarya University. The reinforcing system is composed of hybrid multiaxial seismic fabric consisting of alkali resistant glass and polypropylene fibers. The plaster as bonding material used in the specimen’s retrofitting consists of expanded glass granular. In order to acquire exact measuring data about the failure behavior of the two mortar joints under shear stressing, vertical load-controlled cylinder having force capacity of 50 kN and loading rate of 1.5 mm/min. with an internal inductive displacement transducers is carried out perpendicular to the triplet specimens. In this study, a total of six triplet specimens with textile reinforcement were prepared for these shear bond tests. The three of them were produced as single-sided reinforced triplets with seismic fabric, while the others were strengthened on both sides. In addition, three triplet specimens without retrofitting and plaster were also tested as reference samples. The obtained test results were given in the manner of force-displacement relationships, ductility coefficients and shear strength parameters comparatively. It is concluded that two-side seismic textile applications on masonry elements with relevant plaster have considerably increased the sheer force resistance and the ductility capacity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=expanded%20glass%20granular" title="expanded glass granular">expanded glass granular</a>, <a href="https://publications.waset.org/abstracts/search?q=perforated%20brickwork" title=" perforated brickwork"> perforated brickwork</a>, <a href="https://publications.waset.org/abstracts/search?q=retrofitting" title=" retrofitting"> retrofitting</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20fabric" title=" seismic fabric"> seismic fabric</a>, <a href="https://publications.waset.org/abstracts/search?q=triplet%20shear%20tests" title=" triplet shear tests"> triplet shear tests</a> </p> <a href="https://publications.waset.org/abstracts/75476/triplet-shear-tests-on-retrofitted-brickwork-masonry-walls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75476.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">205</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3375</span> A Study on Shear Field Test Method in Timber Shear Modulus Determination Using Stereo Vision System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Niaz%20Gharavi">Niaz Gharavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hexin%20Zhang"> Hexin Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the structural timber design, the shear modulus of the timber beam is an important factor that needs to be determined accurately. According to BS EN 408, shear modulus can be determined using torsion test or shear field test method. Although torsion test creates pure shear status in the beam, it does not represent the real-life situation when the beam is in the service. On the other hand, shear field test method creates similar loading situation as in reality. The latter method is based on shear distortion measurement of the beam at the zone with the constant transverse load in the standardized four-point bending test as indicated in BS EN 408. Current testing practice code advised using two metallic arms act as an instrument to measure the diagonal displacement of the constructing square. Timber is not a homogenous material, but a heterogeneous and this characteristic makes timber to undergo a non-uniform deformation. Therefore, the dimensions and the location of the constructing square in the area with the constant transverse force might alter the shear modulus determination. This study aimed to investigate the impact of the shape, size, and location of the square in the shear field test method. A binocular stereo vision system was developed to capture the 3D displacement of a grid of target points. This approach is an accurate and non-contact method to extract the 3D coordination of targeted object using two cameras. Two group of three glue laminated beams were produced and tested by the mean of four-point bending test according to BS EN 408. Group one constructed using two materials, laminated bamboo lumber and structurally graded C24 timber and group two consisted only structurally graded C24 timber. Analysis of Variance (ANOVA) was performed on the acquired data to evaluate the significance of size and location of the square in the determination of shear modulus of the beam. The results have shown that the size of the square is an affecting factor in shear modulus determination. However, the location of the square in the area with the constant shear force does not affect the shear modulus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shear%20field%20test%20method" title="shear field test method">shear field test method</a>, <a href="https://publications.waset.org/abstracts/search?q=BS%20EN%20408" title=" BS EN 408"> BS EN 408</a>, <a href="https://publications.waset.org/abstracts/search?q=timber%20shear%20modulus" title=" timber shear modulus"> timber shear modulus</a>, <a href="https://publications.waset.org/abstracts/search?q=photogrammetry%20approach" title=" photogrammetry approach "> photogrammetry approach </a> </p> <a href="https://publications.waset.org/abstracts/85208/a-study-on-shear-field-test-method-in-timber-shear-modulus-determination-using-stereo-vision-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85208.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">211</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3374</span> Influences of Plunge Speed on Axial Force and Temperature of Friction Stir Spot Welding in Thin Aluminum A1100</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suwarsono">Suwarsono</a>, <a href="https://publications.waset.org/abstracts/search?q=Ario%20S.%20Baskoro"> Ario S.

In some cases on aluminum joining, FSW gives better results compared with the arc welding processes, including the quality of welds and produces less distortion.FSW welding process for a light structure and thin materials requires small forces as possible, to avoid structure deflection. The joining process on FSW occurs because of melting temperature and compressive forces, the temperature generation of caused by material deformation and friction between the cutting tool and material. In this research, High speed rotation of spindle was expected to reduce the force required for deformation. The welding material was Aluminum A1100, with thickness of 0.4 mm. The tool was made of HSS material which was shaped by micro grinding process. Tool shoulder diameter is 4 mm, and the length of pin was 0.6 mm (with pin diameter= 1.5 mm). The parameters that varied were the plunge speed (2 mm/min, 3 mm/min, 4 mm/min). The tool speed is fixed at 33,000 rpm. Responses of FSSW parameters to analyze were Axial Force (Z-Force), Temperature and the Shear Strength of welds. Research found the optimum µFSSW parameters, it can be concluded that the most important parameters in the μFSSW process was plunge speed. lowest plunge speed (2 mm / min) causing the lowest axial force (110.40 Newton). The increases of plunge speed will increase the axial force (maximum Z-Farce= 236.03 Newton), and decrease the shear strength of welds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction%20stir%20spot%20welding" title="friction stir spot welding">friction stir spot welding</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminum%20A1100" title=" aluminum A1100"> aluminum A1100</a>, <a href="https://publications.waset.org/abstracts/search?q=plunge%20speed" title=" plunge speed"> plunge speed</a>, <a href="https://publications.waset.org/abstracts/search?q=axial%20force" title=" axial force"> axial force</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20strength" title=" shear strength"> shear strength</a> </p> <a href="https://publications.waset.org/abstracts/55161/influences-of-plunge-speed-on-axial-force-and-temperature-of-friction-stir-spot-welding-in-thin-aluminum-a1100" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55161.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">310</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3373</span> Seismic Evaluation with Shear Walls and Braces for Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20S.%20Malik">R.

This concept has been applied to regular RCC buildings provided with shear walls, braces, and their combinations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20analysis" title="dynamic analysis">dynamic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=displacement" title=" displacement"> displacement</a>, <a href="https://publications.waset.org/abstracts/search?q=pushover%20analysis" title=" pushover analysis"> pushover analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=dual%20structures" title=" dual structures"> dual structures</a>, <a href="https://publications.waset.org/abstracts/search?q=storey%20drift" title=" storey drift"> storey drift</a> </p> <a href="https://publications.waset.org/abstracts/17790/seismic-evaluation-with-shear-walls-and-braces-for-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17790.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">406</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3372</span> Impact of Out-of-Plane Stiffness of the Diaphragm on Deflection of Wood Light-Frame Shear Walls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20M.%20Bagheri">M.

Where research has lacked is in evaluating the impact of out-of-plane raigidity of the diaphragm on the deflection of shear walls. This study aims at investigating the effect of the diaphragm on the behavior of wood light-frame shear walls, in particular its out-of-plane rigidity was simulated by modeling the floors as beam. The out of plane stiffness of the diaphragm was investigated for idealized (infinitely stiff or flexible) as well as “realistic”. The results showed reductions in the shear wall deflection in the magnitude of approximately 80% considering the out of plane rigidity of the diaphragm. It was also concluded that considering conservative estimates of out-of-plane stiffness might lead to a very significant reduction in deflection and that assuming the floor diaphragm to be infinitely rigid out of plan seems to be reasonable. For diaphragms supported on multiple panels, further reduction in the deflection was observed. More work, particularly at the experimental level, is needed to verify the finding obtained in the numerical investigation related to the effect of out of plane diaphragm stiffness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title="finite element analysis">finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20deflection" title=" lateral deflection"> lateral deflection</a>, <a href="https://publications.waset.org/abstracts/search?q=out-of-plane%20stiffness%20of%20the%20diaphragm" title=" out-of-plane stiffness of the diaphragm"> out-of-plane stiffness of the diaphragm</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20light-frame%20shear%20wall" title=" wood light-frame shear wall"> wood light-frame shear wall</a> </p> <a href="https://publications.waset.org/abstracts/106928/impact-of-out-of-plane-stiffness-of-the-diaphragm-on-deflection-of-wood-light-frame-shear-walls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106928.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">182</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3371</span> Calculating Shear Strength Parameter from Simple Shear Apparatus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Nitesh">G.

Therefore, it is important to determine reliable values for the accuracy of stability analysis. Direct shear tests are mostly performed to determine the shear strength of cohesionless soils. The major limitation of the direct shear test is that the failure takes place through the pre-defined failure plane but the failure is not along pre-defined plane and is along the weakest plane in actual shearing mechanism that goes on in the field. This leads to overestimating the strength parameter; hence, a new apparatus called simple shear is developed and used in this study to determine the shear strength parameter that simulates the field conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=direct%20shear" title="direct shear">direct shear</a>, <a href="https://publications.waset.org/abstracts/search?q=simple%20shear" title=" simple shear"> simple shear</a>, <a href="https://publications.waset.org/abstracts/search?q=angle%20of%20shear%20resistance" title=" angle of shear resistance"> angle of shear resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=cohesionless%20soils" title=" cohesionless soils"> cohesionless soils</a> </p> <a href="https://publications.waset.org/abstracts/15739/calculating-shear-strength-parameter-from-simple-shear-apparatus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15739.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">411</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3370</span> Numerical Study on the Hazards of Gravitational Forces on Cerebral Aneurysms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hashem%20M.%20Alargha">Hashem M.

Longissimus dorsi) and broiler carcass through the addition of liquid smoke as a natural preservative. This study was using Longissimus dorsi muscle from male Bali beef aged 3 years, broiler breast and thigh aged 40 days. Three types of meat were marinated in liquid smoke with concentrations of 0, 5, and 10% for 30 minutes at the level of 20% of the sample weight (w/w). The samples were storage at 2-5°C for 1 month. This study designed as a factorial experiment 3 x 3 x 4 based on a completely randomized design with 5 replications; the first factor was meat type (beef, chicken breast and chicken thigh); the 2nd factor was liquid smoke concentrations (0, 5, and 10%), and the 3rd factor was storage duration (1, 2, 3, and 4 weeks). Parameters measured were TBA value, total bacterial colonies, water holding capacity (WHC), shear force value both before and after cooking (80°C – 15min.), and cooking loss. The results showed that the type of meat produced WHC, shear force value, cooking loss and TBA differed between the three types of meat. Higher concentration of liquid smoke, the WHC, shear force value, TBA, and total bacterial colonies were decreased; at a concentration of 10% of liquid smoke, the total bacterial colonies decreased by 57.3% from untreated with liquid smoke. Longer storage, the total bacterial colonies and WHC were increased, while the shear force value and cooking loss were decreased. It can be concluded that a 10% concentration of liquid smoke was able to maintain fat oxidation and bacterial growth in Bali beef and chicken breast and thigh. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bali%20beef" title="Bali beef">Bali beef</a>, <a href="https://publications.waset.org/abstracts/search?q=chicken%20meat" title=" chicken meat"> chicken meat</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20smoke" title=" liquid smoke"> liquid smoke</a>, <a href="https://publications.waset.org/abstracts/search?q=meat%20quality" title=" meat quality"> meat quality</a> </p> <a href="https://publications.waset.org/abstracts/36881/quality-of-bali-beef-and-broiler-after-immersion-in-liquid-smoke-on-different-concentrations-and-storage-times" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36881.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">392</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3368</span> Particle Size Effect on Shear Strength of Granular Materials in Direct Shear Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Alias">R.

Steel plate sheathing is often used with these panels made of cold formed steel (CFS) to improve its shear strength. In order to predict the shear strength resistance, two methods are presented in this paper. In the first method, the steel plate sheathing is modeled with plats strip taking into account only the tension and compression force due to the horizontal load, where both track and stud are modeled according to the geometrical and mechanical characteristics of the specimen used in the experiments. The theoretical background and empirical formulations of this method are presented in this paper. However, the second method is based on a micro modeling of the cold formed steel Shear Wall Panel “CFS-SWP” using Abaqus software. A nonlinear analysis was carried out with an in-plan monotonic load. Finally, the comparison between these two methods shows that the micro modeling with Abaqus gives better prediction of shear resistance of SWP than strips method. However, the latter is easier and less time consuming than the micro modeling method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cold%20formed%20steel%20%27CFS%27" title="cold formed steel 'CFS'">cold formed steel 'CFS'</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20wall%20panel" title=" shear wall panel"> shear wall panel</a>, <a href="https://publications.waset.org/abstracts/search?q=strip%20method" title=" strip method"> strip method</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20elements" title=" finite elements"> finite elements</a> </p> <a href="https://publications.waset.org/abstracts/46456/numerical-evaluation-of-shear-strength-for-cold-formed-steel-shear-wall-panel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46456.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">309</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3366</span> Electrokinetic Transport of Power Law Fluid through Hydrophobic Micro-Slits</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ainul%20Haque">Ainul Haque</a>, <a href="https://publications.waset.org/abstracts/search?q=Ameeye%20Kumar%20Nayak"> Ameeye Kumar Nayak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flow enhancement and species transport in a slit hydrophobic microchannel is studied for non-Newtonian fluids with the externally imposed electric field and pressure gradient.

The analytical quantification of velocity and pressure of electroosmotic flow (EOF) is made with the numerical results due to the staggered grid based finite volume method for flow governing equations. The resistance force due to fluid friction and shear force along the surface are decreased by the hydrophobicity, enables the faster movement of fluid particles.

For analysis of soil stability problems such as bearing capacity, slope stability and lateral pressure on soil retaining structures, the shear strength parameters must be known well. In the present study, shear strength parameters are determined in silty-sand mixtures. Direct shear tests are performed on 161 Firoozkooh sand with different silt content at a relative density of 70% in three vertical stress of 100, 150, and 200 kPa. Wet tamping method is used for soil sample preparation, and the results include diagrams of shear stress versus shear deformation and sample height changes against shear deformation. Accordingly, in different silt percent, the shear strength parameters of the soil such as internal friction angle and dilation angle are calculated and compared. According to the results, when the sample contains up to 10% silt, peak shear strength and internal friction angle have an upward trend. However, if the sample contains 10% to 50% of silt a downward trend is seen in peak shear strength and internal friction angle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shear%20strength%20parameters" title="shear strength parameters">shear strength parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20shear%20test" title=" direct shear test"> direct shear test</a>, <a href="https://publications.waset.org/abstracts/search?q=silty%20sand" title=" silty sand"> silty sand</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20stress" title=" shear stress"> shear stress</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20deformation" title=" shear deformation"> shear deformation</a> </p> <a href="https://publications.waset.org/abstracts/106132/effect-of-silt-presence-on-shear-strength-parameters-of-unsaturated-sandy-soils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106132.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">163</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3363</span> Interaction Diagrams for Symmetrically Reinforced Concrete Square Sections Under 3 Dimensional Multiaxial Loading Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Androniki-Anna%20Doulgeroglou">Androniki-Anna Doulgeroglou</a>, <a href="https://publications.waset.org/abstracts/search?q=Panagiotis%20Kotronis"> Panagiotis Kotronis</a>, <a href="https://publications.waset.org/abstracts/search?q=Giulio%20Sciarra"> Giulio Sciarra</a>, <a href="https://publications.waset.org/abstracts/search?q=Catherine%20Bouillon"> Catherine Bouillon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The interaction diagrams are functions that define ultimate states expressed in terms of generalized forces (axial force, bending moment and shear force). Two characteristic states for reinforced concrete (RC) sections are proposed: the first characteristic state corresponds to the yield of the reinforcement bars and the second to the peak values of the generalized forces generalized displacements curves. 3D numerical simulations are then conducted for RC columns and the global responses are compared to experimental results. Interaction diagrams for combined flexion, shear and axial force loading conditions are numerically produced for symmetrically RC square sections for different reinforcement ratios.

Comparison with interaction diagrams from the Eurocode is finally presented for the study cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20convex%20expressions" title="analytical convex expressions">analytical convex expressions</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction%20diagrams" title=" interaction diagrams"> interaction diagrams</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete" title=" reinforced concrete"> reinforced concrete</a> </p> <a href="https://publications.waset.org/abstracts/150050/interaction-diagrams-for-symmetrically-reinforced-concrete-square-sections-under-3-dimensional-multiaxial-loading-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150050.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3362</span> Comparative Study of the Distribution of Seismic Loads of Buildings with Asymmetries Plan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Hamza%20Yache">Ahmed Hamza Yache</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main purpose of this study is to estimate the distribution of shear forces in building structures with asymmetries in the plan submitted to seismic forces can cause, in this case, simultaneous deformations of translation and torsion. To this end, the distribution of shear forces is obtained by seismic forces calculated from the equivalent static method of the Algerian earthquake code RPA 99 (2003 version) and spectral modal analysis for an irregular building plan without kinks. Comparison of the results obtained by these two methods used to highlight the difference in terms of distributions of shear forces in such structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=structure" title="structure">structure</a>, <a href="https://publications.waset.org/abstracts/search?q=irregular" title=" irregular"> irregular</a>, <a href="https://publications.waset.org/abstracts/search?q=code" title=" code"> code</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic" title=" seismic"> seismic</a>, <a href="https://publications.waset.org/abstracts/search?q=method" title=" method"> method</a>, <a href="https://publications.waset.org/abstracts/search?q=force" title=" force"> force</a>, <a href="https://publications.waset.org/abstracts/search?q=period" title=" period"> period</a> </p> <a href="https://publications.waset.org/abstracts/20627/comparative-study-of-the-distribution-of-seismic-loads-of-buildings-with-asymmetries-plan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20627.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">585</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3361</span> Numerical Analysis of Cold-Formed Steel Shear Wall Panels Subjected to Cyclic Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Meddah">H.

Bourahla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Shear walls made of cold formed steel are used as lateral force resisting components in residential and low-rise commercial and industrial constructions. The seismic design analysis of such structures is often complex due to the slenderness of members and their instability prevalence. In this context, a simplified modeling technique across the panel is proposed by using the finite element method. The approach is based on idealizing the whole panel by a nonlinear shear link element which reflects its shear behavior connected to rigid body elements which transmit the forces to the end elements (studs) that resist the tension and the compression. The numerical model of the shear wall panel was subjected to cyclic loads in order to evaluate the seismic performance of the structure in terms of lateral displacement and energy dissipation capacity. In order to validate this model, the numerical results were compared with those from literature tests. This modeling technique is particularly useful for the design of cold formed steel structures where the shear forces in each panel and the axial forces in the studs can be obtained using spectrum analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cold-formed%20steel" title="cold-formed steel">cold-formed steel</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20loading" title=" cyclic loading"> cyclic loading</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling%20technique" title=" modeling technique"> modeling technique</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20analysis" title=" nonlinear analysis"> nonlinear analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20wall%20panel" title=" shear wall panel"> shear wall panel</a> </p> <a href="https://publications.waset.org/abstracts/55753/numerical-analysis-of-cold-formed-steel-shear-wall-panels-subjected-to-cyclic-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55753.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">292</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3360</span> Shear Strength of Unsaturated Clayey Soils Using Laboratory Vane Shear Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Ziaie%20Moayed">Reza Ziaie Moayed</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Abdolhassan%20Naeini"> Seyed Abdolhassan Naeini</a>, <a href="https://publications.waset.org/abstracts/search?q=Peyman%20Nouri"> Peyman Nouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Yekehdehghan"> Hamed Yekehdehghan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The shear strength of soils is a significant parameter in the design of clay structures, depots, clay gables, and freeways. Most research has addressed the shear strength of saturated soils. However, soils can become partially saturated with changes in weather, changes in groundwater levels, and the absorption of water by plant roots. Hence, it is necessary to study the strength behavior of partially saturated soils. The shear vane test is an experiment that determines the undrained shear strength of clay soils. This test may be performed in the laboratory or at the site. The present research investigates the effect of liquidity index (LI), plasticity index (PI), and saturation degree of the soil on its undrained shear strength obtained from the shear vane test. According to the results, an increase in the LI and a decrease in the PL of the soil decrease its undrained shear strength. Furthermore, studies show that a rise in the degree of saturation decreases the shear strength obtained from the shear vane test. <p class="card-text"><strong>Keywords:</strong> <a
