Several other plastic criterion such as tangent intersection (TI) criterion, plastic work (PW) criterion have been proposed in the literature, but all exhibit a practical limitation: difficult to define the load parameter for vessels subject to several combined loads. An alternative criterion: plastic work-tangent (PWT) criterion for evaluating plastic load in pressure vessel design by analysis is presented in this paper. According to the plastic work-load curve, when the tangent variation is less than a given value in the plastic phase, the corresponding load is the plastic load. Application of the proposed criterion is illustrated by considering the elastic-plastic response of the lower head of reactor pressure vessel (RPV) and nozzle intersection of (RPV). It is proposed that this is because the PWT criterion more fully represents the constraining effect of material strain hardening on the spread of plastic deformation and more efficiently ton evaluating the plastic load. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plastic%20load" title="plastic load">plastic load</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20work" title=" plastic work"> plastic work</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20hardening" title=" strain hardening"> strain hardening</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20work-tangent%20criterion" title=" plastic work-tangent criterion"> plastic work-tangent criterion</a> </p> <a href="https://publications.waset.org/abstracts/59204/a-criterion-for-evaluating-plastic-loads-plastic-work-tangent-criterion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59204.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">355</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">1423</span> Pushover Analysis of Reinforced Concrete Beam-Column Joint Strengthening with Ultra High Performance Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulsamee%20Halahla">Abdulsamee Halahla</a>, <a href="https://publications.waset.org/abstracts/search?q=Emad%20Allout"> Emad Allout</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this research is to study the behavior of exterior beam-column joints (BCJs) strengthened with ultra-high performance concrete (UHPC), in terms of the shear strength and maximum displacement using pushover analysis at the tip of the beam. A finite element (F.E) analysis was performed to study three main parameters – the level of the axial load in the column (N), the beam shear reinforcement (Av/s)B, and the effect of using UHPC. The normal concrete at the studied joint region was replaced by UHPC. The model was verified by using experimental results taken from the literature. The results showed that the UHPC contributed to the transference of the plastic hinge from the joint to the beam-column interface. In addition, the strength of the UHPC-strengthened joints was enhanced dramatically from 8% to 38% for the joints subjected to 12.8MPa and zero axial loads, respectively. Moreover, the UHPC contributed in improving the maximum deflection. This improvement amounted to 1% and 176% for the joints subjected to zero and 12.8MPa axial load, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultra%20high%20performance%20concrete" title="ultra high performance concrete">ultra high performance concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility" title=" ductility"> ductility</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete%20joints" title=" reinforced concrete joints"> reinforced concrete joints</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20modeling" title=" finite element modeling"> finite element modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20behavior%3B%20pushover%20analysis" title=" nonlinear behavior; pushover analysis"> nonlinear behavior; pushover analysis</a> </p> <a href="https://publications.waset.org/abstracts/123132/pushover-analysis-of-reinforced-concrete-beam-column-joint-strengthening-with-ultra-high-performance-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123132.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">135</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">1422</span> Effect of Welding Processes on Tensile Behavior of Aluminum Alloy Joints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chaitanya%20Sharma">Chaitanya Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Vikas%20Upadhyay"> Vikas Upadhyay</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Tripathi"> A.

Numerical investigations are performed using a nonlinear finite element ( FE) analysis by incorporating damage plasticity model (CDP), for material behaviour the concrete response in compression, tension softening were used, linear plastic with isotropic hardening for reinforcing steel, and linear elastic lamina material model for CFRP sheets using the commercial FE software ABAQUS. The numerical models developed in the present study are validated with the results obtained from the experiment under monotonic loading using the hydraulic Jack in displacement control mode. The experimental program includes casting of deficient BCJ loaded to failure load for both un-strengthened and strengthened BCJ. The failure mode, and deformation response of CFRP strengthened and un-strengthened joints and propagation of damage in the components of BCJ are discussed. Finite element simulations are compared with the experimental result and are noted to yield reasonable comparisons. The damage plasticity model was able to capture with good accuracy of the ultimate load and the mode of failure in the beam column joint. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete" title="reinforced concrete">reinforced concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=exterior%20beam-column%20joints" title=" exterior beam-column joints"> exterior beam-column joints</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete%20damage%20plasticity%20model" title=" concrete damage plasticity model"> concrete damage plasticity model</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20simulation" title=" computational simulation"> computational simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=3-D%20finite%20element%20model" title=" 3-D finite element model"> 3-D finite element model</a> </p> <a href="https://publications.waset.org/abstracts/41069/finite-element-simulation-of-rc-exterior-beam-column-joints-using-damage-plasticity-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41069.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">383</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">1419</span> Experimental Investigation of Bituminous Roads with Waste Plastic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arjita%20Biswas">Arjita Biswas</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandeep%20Potnis"> Sandeep Potnis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plastic roads (bituminous roads using waste plastic in the wearing course ) have now become familiar in the Road Construction Sector in India.

The nanoparticles are added in two different concentrations, to an epoxy-based two-component structural adhesive, Araldite 2011, to survey the influences of the nanoparticle weight percentage on the failure load of the joints compared to that of the joints manufactured by the neat adhesive. The effects of being exposure to a moist ambience on the joint strength are also investigated for the joints produced of both neat and modified adhesives. For this purpose, an ageing process was carried out on the joints of both neat and improved kinds with variable immersion periods (20, 40 and 60 days). All the specimens were tested under a quasi-static tensile loading of 2 mm/min speed so as to find the quantities of the failure loads. Outcomes indicate that the failure loads of the joints with modified adhesives are measurably higher than that of the joint with neat adhesive, even while being put for a while under a moist condition. Another result points out that humidity lessens the bonding strength of all the joints of both types as the exposure time increases, which can be attributed to the change in the failure mode. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bonding%20strength" title="bonding strength">bonding strength</a>, <a href="https://publications.waset.org/abstracts/search?q=humidity" title=" humidity"> humidity</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-silica" title=" nano-silica"> nano-silica</a>, <a href="https://publications.waset.org/abstracts/search?q=scarf%20joint" title=" scarf joint"> scarf joint</a> </p> <a href="https://publications.waset.org/abstracts/115145/bonding-strength-of-adhesive-scarf-joints-improved-by-nano-silica-subjected-to-humidity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115145.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">173</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">1416</span> Levels of Plastic Waste and Fish Landed By Beach Seine Fishers in Coastal Ghana</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francis%20Gbogbo">Francis Gbogbo</a>, <a href="https://publications.waset.org/abstracts/search?q=Angelica%20Ama%20Essandoh"> Angelica Ama Essandoh</a>, <a href="https://publications.waset.org/abstracts/search?q=Wendy%20Teresa%20Baffoe"> Wendy Teresa Baffoe</a>, <a href="https://publications.waset.org/abstracts/search?q=Henry%20Groos"> Henry Groos</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20Mario%20Boateng"> Charles Mario Boateng</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Robert%20Blankson"> Emmanuel Robert Blankson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Baseline data on plastic landing by fishers and monitoring of this is important in evaluating the success of plastic waste management efforts. This study investigated plastic and fish landed by beach seine fishers in Ghana, together with the rate of plastic deposition on an adjoining beach. Plastic constituted 31.6% of the total catch, and 41.7% of the fish landed by weight. There were significant differences between the average weight of fish (139.58±53.6kg) and plastic (65.73±14.6kg) landed per fishing session and the catch per unit effort of fish (183.4±76.7 kg/day) and plastic (88.4±35.2 kg/day). The mean weight of plastic landed per fishing session was higher than the mean weight of each of the 26 species of fisheries. The rate of plastic deposition on the beach was 8.1±2.5 plastic items per m2 per tidal cycle or 0.35±0.11kg plastic per m2 per tidal cycle, with food packs and tableware dominating the deposited plastic. The results suggested that ongoing water sachets and plastic bottle recycling in Ghana are yielding results and calls for targeted efforts in plastic food packs and tableware management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fishig" title="fishig">fishig</a>, <a href="https://publications.waset.org/abstracts/search?q=landing" title=" landing"> landing</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20waste" title=" plastic waste"> plastic waste</a>, <a href="https://publications.waset.org/abstracts/search?q=intertidal%20area" title=" intertidal area"> intertidal area</a>, <a href="https://publications.waset.org/abstracts/search?q=fishing%20effort" title=" fishing effort"> fishing effort</a> </p> <a href="https://publications.waset.org/abstracts/181875/levels-of-plastic-waste-and-fish-landed-by-beach-seine-fishers-in-coastal-ghana" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181875.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">91</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">1415</span> Effects of Geometrical Parameters on Static Strength of Tubular KT-Joints at Fire Condition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Ahmadi">Hamid Ahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Neda%20Azari%20Dodaran"> Neda Azari Dodaran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to study the structural behavior of tubular KT-joints subjected to axial loading at fire induced elevated temperatures. At first, a finite element (FE) model was developed and validated against the data available from experimental tests. Then, a set of 810 FE analyses were performed to study the influence of temperature and dimensionless geometrical parameters (β, γ, θ, and τ) on the ultimate strength and initial stiffness. The joints were analyzed under two types of axial loading and five different temperatures (20 ºC, 200 ºC, 400 ºC, 550 ºC, and 700 ºC). Results show that the ultimate strength and initial stiffness of KT-joints decrease considerably by increasing the temperature. In the joints having bigger values of the β, the temperature elevation leads to less reduction in ultimate strength; while in the joints with bigger values of the γ, the temperature elevation results in more reduction in ultimate strength. The influence of the θ on the ultimate strength is independent from the temperature. To our knowledge, there is no design formula available for determining the ultimate strength of KT-joints at elevated temperatures. Hence, after parametric study, two equations were developed through nonlinear regression, for calculating the ultimate strength of KT-joints at elevated temperatures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axial%20loads" title="axial loads">axial loads</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20condition" title=" fire condition"> fire condition</a>, <a href="https://publications.waset.org/abstracts/search?q=parametric%20formula" title=" parametric formula"> parametric formula</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20strength" title=" static strength"> static strength</a>, <a href="https://publications.waset.org/abstracts/search?q=tubular%20KT-joint" title=" tubular KT-joint"> tubular KT-joint</a> </p> <a href="https://publications.waset.org/abstracts/90190/effects-of-geometrical-parameters-on-static-strength-of-tubular-kt-joints-at-fire-condition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90190.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">154</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">1414</span> Effect of Horizontal Joint Reinforcement on Shear Behaviour of RC Knee Connections</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Zhang">N.

In the experimental programme, particular emphasis was given to the effect of horizontal reinforcement (in format of inverted U-shape bars) on the shear strength and ductility capacity of knee joints. Test results are compared with those predicted by four seismic design codes, including ACI 318-14, EC8, NZS3101 and GB50010.

In this study on hybrid joints, quasi-static experiments and finite element analysis were performed to investigate the failure mechanism of hybrid composite joint with respect to the joint properties such as the adhesive material, clamping force, and joint geometry. The outcomes demonstrated that the stiffness of the adhesive is the most imperative design parameter. In this investigation, two adhesives with various stiffness values were utilized. Regarding the joints utilizing the adhesive with the lower stiffness modulus, it was observed that the load was exchanged promptly through the adhesive since it was shared more proficiently between the bolt and adhesive. This phenomenon permitted the hybrid joints with low-modulus adhesive to support more prominent loads before failure when contrasted with the joints that utilize the stiffer adhesive. In the next step, the stress share between the bond and bolt as a function of various design parameters was studied using a finite element model in which it was understood that the geometrical parameters such as joint overlap and width have a significant influence on the load sharing between the bolt and the adhesive. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20joints" title="composite joints">composite joints</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20materials" title=" composite materials"> composite materials</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20joints" title=" hybrid joints"> hybrid joints</a>, <a href="https://publications.waset.org/abstracts/search?q=single-lap%20joint" title=" single-lap joint"> single-lap joint</a> </p> <a href="https://publications.waset.org/abstracts/85844/studying-the-load-sharing-and-failure-mechanism-of-hybrid-composite-joints-using-experiment-and-finite-element-modeling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85844.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">1412</span> Effects of Repeated High Loadings on the Performance of Adhesively-Bonded Single Lap Joints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Orkun%20Yavuz">Orkun Yavuz</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferhat%20Kadio%C4%9Flu"> Ferhat Kadioğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Emin%20Ercan"> M.

A projectile with a mass of 1.25 gr and density of 11.3 gr/cm3 was fired at the joints with a velocity of about 280 m/s using a specially designed experimental set-up, and the impact was recorded via a high-speed camera. The SLJs were manufactured from 6061 aluminum adherend (AA6061) material and an adhesive film. The joints, which have an adherend thickness of 4 mm and overlap length of 15 mm, were subjected to up to 3 shots for the ballistic test, followed by quasi-static tensile testing. The impacted joints, then, were compared to the non-impacted and one-shot impacted ones, which was a subject of investigation carried out before. It was found that while the joints subjected to 2 shots mechanically deteriorated, those subjected to 3 shots experienced a complete failure at the end of the experiment. A numerical study was also conducted using an ABAQUS package program. While the adherends were modelled using the Johnson-Cook deformation parameters, an elastoplastic behavior of the adhesive was used as input data in the analyses. It seems the experimental results confirm the numerical ones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ballistic%20tests" title="ballistic tests">ballistic tests</a>, <a href="https://publications.waset.org/abstracts/search?q=adhesive%20joints" title=" adhesive joints"> adhesive joints</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20analysis" title=" numerical analysis"> numerical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=SLJ" title=" SLJ"> SLJ</a> </p> <a href="https://publications.waset.org/abstracts/180863/effects-of-repeated-high-loadings-on-the-performance-of-adhesively-bonded-single-lap-joints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/180863.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">64</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">1411</span> Numerical Analysis of Crack's Effects in a Dissimilar Welded Joint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20N.%20L.%20Alves">Daniel N.

As soon, to understand the response of materials when submitted to adverse conditions is essential to design a safety project. This work investigates the presence of cracks in dissimilar welded joints (DWJ). Its fracture toughness responses depend upon the heterogeneity present in these joints. Thus, this work aim analyzing the behavior of the crack tip zone located in a buttery dissimilar welded joint (ASTM A-36, Inconel, and AISI 8630 M) used in the union of pipes present in the offshore oil production lines. The crack was placed 1 mm from fusion line (FL) Inconel-AISI 8630 M toward the AISI 8630 M. Finite Element Method (FEM) was used to analyze stress and strain fields generated during the loading imposed on the specimen. It was possible observing critical stress area by the numerical tool as well as a preferential plastic flow was also observed in the sample of dissimilar welded joint, which can be considered a harbinger of the crack growth path. The results obtained through numerical analysis showed a convergent behavior in relation to the plastic flow, qualitatively and quantitatively, in agreement with previous performed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crack" title="crack">crack</a>, <a href="https://publications.waset.org/abstracts/search?q=dissimilar%20welded%20joint" title=" dissimilar welded joint"> dissimilar welded joint</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20analysis" title=" numerical analysis"> numerical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20field" title=" strain field"> strain field</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20stress%20field" title=" the stress field"> the stress field</a> </p> <a href="https://publications.waset.org/abstracts/88025/numerical-analysis-of-cracks-effects-in-a-dissimilar-welded-joint" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88025.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">171</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">1410</span> Determination of Resistance to Freezing of Bonded Façade Joint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20Ne%C4%8Dasov%C3%A1">B.

The potential of bonded joints is studied and described in more detail. The paper presents the results of an experimental and theoretical research about the effects of freeze cycling on the bonded joint. For the purpose of tests spruce timber profiles were chosen for the load bearing substructure. Planks from wooden plastic composite and Siberian larch are representing facade cladding. Two types of industrial polyurethane adhesives intended for structural bonding were selected. The article is focused on the preparation as well as on the subsequent curing and conditioning of test samples. All test samples were subjected to 15 cycles that represents sudden temperature changes, i.e. immersion in a water bath at (293.15 ± 3) K for 6 hours and subsequent freezing to (253.15 ± 2) K for 18 hours. Furthermore, the retention of bond strength between substructure and cladding was tested and strength in shear was determined under tensile stress. Research data indicate that little, if any, damage to the bond results from freezing cycles. Additionally, the suitability of selected group of adhesives in combination with timber substructure was confirmed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adhesive%20system" title="adhesive system">adhesive system</a>, <a href="https://publications.waset.org/abstracts/search?q=bonded%20joints" title=" bonded joints"> bonded joints</a>, <a href="https://publications.waset.org/abstracts/search?q=wooden%20lightweight%20fa%C3%A7ade" title=" wooden lightweight façade"> wooden lightweight façade</a>, <a href="https://publications.waset.org/abstracts/search?q=timber%20substructure" title=" timber substructure"> timber substructure</a> </p> <a href="https://publications.waset.org/abstracts/24206/determination-of-resistance-to-freezing-of-bonded-facade-joint" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24206.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">391</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">1409</span> Slip Limit Prediction of High-Strength Bolt Joints Based on Local Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chang%20He">Chang He</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Tamura"> Hiroshi Tamura</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Katsuchi"> Hiroshi Katsuchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiaqi%20Wang"> Jiaqi Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the aim is to infer the slip limit (static friction limit) of contact interfaces in bolt friction joints by analyzing other bolt friction joints with the same contact surface but in a different shape.

The determination of DoB values in a tubular joint is essential for improving the accuracy of fatigue life estimation using the stress-life (S–N) method and particularly for predicting the fatigue crack growth based on the fracture mechanics (FM) approach. In the present paper, data extracted from finite element (FE) analyses of tubular KT-joints, verified against experimental data and parametric equations, was used to investigate the effects of geometrical parameters on DoB values at the crown 0˚, saddle, and crown 180˚ positions along the weld toe of central brace in tubular KT-joints subjected to axial loading. Parametric study was followed by a set of nonlinear regression analyses to derive DoB parametric formulas for the fatigue analysis of KT-joints under axial loads. The tubular KT-joint is a quite common joint type found in steel offshore structures. However, despite the crucial role of the DoB in evaluating the fatigue performance of tubular joints, this paper is the first attempt to study and formulate the DoB values in KT-joints. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tubular%20KT-joint" title="tubular KT-joint">tubular KT-joint</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue" title=" fatigue"> fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=degree%20of%20bending%0D%0A%28DoB%29" title=" degree of bending (DoB)"> degree of bending (DoB)</a>, <a href="https://publications.waset.org/abstracts/search?q=axial%20loading" title=" axial loading"> axial loading</a>, <a href="https://publications.waset.org/abstracts/search?q=parametric%20formula" title=" parametric formula "> parametric formula </a> </p> <a href="https://publications.waset.org/abstracts/26817/degree-of-bending-in-axially-loaded-tubular-kt-joints-of-offshore-structures-parametric-study-and-formulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26817.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">361</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">1407</span> Seismic Response of Moment Resisting Steel Frame with Hysteresis Envelope Model of Joints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Krolo%20Paulina">Krolo Paulina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The seismic response of moment-resisting steel frames depends on the behavior of the joints, especially when they are considered as ductile zones.

The results show that with the addition of waste plastic fibers, the MDD and OMC and also the compressibility of soil decrease significantly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=silty%20soil" title="silty soil">silty soil</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20plastic" title=" waste plastic"> waste plastic</a>, <a href="https://publications.waset.org/abstracts/search?q=compaction" title=" compaction"> compaction</a>, <a href="https://publications.waset.org/abstracts/search?q=consolidation" title=" consolidation"> consolidation</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforcement" title=" reinforcement"> reinforcement</a> </p> <a href="https://publications.waset.org/abstracts/108863/influence-of-plastic-waste-reinforcement-on-compaction-and-consolidation-behavior-of-silty-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108863.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">173</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">1405</span> Beam, Column Joints Concrete in Seismic Zone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalifa%20Kherafa">Khalifa Kherafa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This east project consists in studying beam–column joints concrete subjected to seismic loads.

The premature failure of such connections would severely limit the seismic performance and increase the vulnerability of RCMRF. In the past decades, researchers primarily focused on investigating the structural behaviour and failure mechanisms of conventional beam-column joints, the beam width of which is either smaller than or equal to the column width, while studies in wide beam-column joints were scarce. This paper presents the preliminary experimental results of two full-scale exterior wide beam-column connections, which are mainly designed and detailed according to ACI 318-14 and ACI 352R-02, under reversed cyclic loading. The ratios of the design shear force to the nominal shear strength of these specimens are 1.0 and 1.7, respectively, so as to probe into differences of the joint shear strength between experimental results and predictions by design codes of practice. Flexural failure dominated in the specimen with ratio of 1.0 in which full-width plastic hinges were observed, while both beam hinges and post-peak joint shear failure occurred for the other specimen. No sign of premature joint shear failure was found which is inconsistent with ACI codes’ prediction. Finally, a modification of current codes of practice is provided to accurately predict the joint shear strength in wide beam-column joint. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=joint%20shear%20strength" title="joint shear strength">joint shear strength</a>, <a href="https://publications.waset.org/abstracts/search?q=reversed%20cyclic%20loading" title=" reversed cyclic loading"> reversed cyclic loading</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20vulnerability" title=" seismic vulnerability"> seismic vulnerability</a>, <a href="https://publications.waset.org/abstracts/search?q=wide%20beam-column%20joints" title=" wide beam-column joints"> wide beam-column joints</a> </p> <a href="https://publications.waset.org/abstracts/59134/cyclic-behaviour-of-wide-beam-column-joints-with-shear-strength-ratios-of-10-and-17" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59134.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">323</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">1402</span> Experimental Model of the Behaviour of Bolted Angles Connections with Stiffeners</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulkadir%20Cuneyt%20Aydin">Abdulkadir Cuneyt Aydin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahyar%20Maali"> Mahyar Maali</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmut%20K%C4%B1l%C4%B1%C3%A7"> Mahmut Kılıç</a>, <a href="https://publications.waset.org/abstracts/search?q=Merve%20Sa%C4%9F%C4%B1ro%C4%9Flu"> Merve Sağıroğlu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The moment-rotation curves of semi-rigid connections are the visual expressions of the actual behaviour discovered in beam-to-column connections experiments. This research was to determine the behaviour of the connection using full-scale experiments under statically loaded. The stiffeners which are typically attached to beams web or flanges to control local buckling and to increase shear capacity in a beam web are almost always used in modern designs. They must also provide sufficient moment of inertia to control out of plane deformations. This study was undertaken to analyse the influence of stiffeners in the angles and beams on the behaviour of the beam-to-column joints. In addition, the aim was to provide necessary data to improve the Eurocode 3. The main parameters observed are the evolution of the resistance, the stiffness, the rotation capacity, the ductility of a joint and the Energy Dissipation. Experimental tests show that the plastic flexural resistance and the energy dissipation increased when thickness of stiffener beam, thickness of stiffener angles were increased in the test specimens. And also, while stiffness of joints, the bending moment capacity and the maximum bending moment increased with the increasing thickness of stiffener beam, these values decreased with the increasing thickness of stiffener angles. So, it is observed that the beam stiffener of angles are important in improving resistance moment of beam-to-column semi-rigid joints. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bolted%20angles%20connection" title="bolted angles connection">bolted angles connection</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-rigid%20joints" title=" semi-rigid joints"> semi-rigid joints</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility%20of%20a%20joint" title=" ductility of a joint"> ductility of a joint</a>, <a href="https://publications.waset.org/abstracts/search?q=angles%20and%20beams%20stiffeners" title=" angles and beams stiffeners"> angles and beams stiffeners</a> </p> <a href="https://publications.waset.org/abstracts/54503/experimental-model-of-the-behaviour-of-bolted-angles-connections-with-stiffeners" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54503.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">460</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">1401</span> The Influence of Brazing Method on Corrosion Behavior of Brazed Aluminum Joints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Ghasim-akbari">F.

This paper reports a part of a work to investigate the corrosion behavior of brazed Al6061 using Al4047 as filler metal with and without the use of flux to discover the effect of different brazing atmospheres. The samples brazed under air, vacuum, argon, and hydrogen atmospheres. The interfacial area of the joints was examined to ensure being free of any defects. The sides of each test piece were covered with insulator and the surface of the joint was encountered to polarization test. The results revealed a significant difference of corrosion resistance. The samples that brazed under argon and hydrogen atmospheres had better corrosion resistance than other samples. Microstructure of the corroded joints revealed that the amount of the filler metal is a critical parameter on corrosion resistance of the joints. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brazing" title="brazing">brazing</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion%20behavior" title=" corrosion behavior"> corrosion behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=Al6061" title=" Al6061"> Al6061</a>, <a href="https://publications.waset.org/abstracts/search?q=polarization" title=" polarization"> polarization</a> </p> <a href="https://publications.waset.org/abstracts/24594/the-influence-of-brazing-method-on-corrosion-behavior-of-brazed-aluminum-joints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24594.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">498</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">1400</span> Plastic Degradation Activity of Bacillus Sp.

The persistence of plastic wastes in the environment formed a serious problem. They are prominent with their capability to resist microbial degradation for decades. Thus, it was crucial to find ways to eliminate the plastics without depending on conventional recycling methods, which causes the formation of more hazardous compounds and doubles the problem. In this paper, mealworms were fed with a mixture of plastic wastes such as plastic bags, Styrofoam, PE foam, and plastic tarpaulins film as the sole food source for a month. Frass was collected at the end of the test and examined using FTIR analysis. Also, the gut bacteria were isolated and identified using 16S rRNA. The results show the mineralization of plastic in the frass of plastic-fed worms when compared to control. The 16S rRNA and the BLAST analysis showed that the obtained isolate belongs to the genus Bacillus Sp especially Bacillus subtilis. Phylogenetic analysis showed their relatedness to the other Bacillus species in the NCBI database. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mealworm" title="mealworm">mealworm</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20management" title=" waste management"> waste management</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic-degrading%20bacteria" title=" plastic-degrading bacteria"> plastic-degrading bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=gut%20microbiome" title=" gut microbiome"> gut microbiome</a>, <a href="https://publications.waset.org/abstracts/search?q=Bacillus%20sp" title=" Bacillus sp"> Bacillus sp</a> </p> <a href="https://publications.waset.org/abstracts/146184/plastic-degradation-activity-of-bacillus-sp-isolated-from-the-gut-of-plastic-fed-yellow-mealworm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146184.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">146</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">1399</span> Lapped Gussets Joints in Compression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20R.%20Tshunza">K.

The structural integrity of precast reinforced concrete (RC) constructions is influenced by the effectiveness of the joints and connections. This paper contains an analytical study about four types of precast reinforced concrete frames, which vary according to the number of storeys and the number of bays with two different types of moment-resisting beam-to-column connection is investigated under cyclic displacement loading up to 5.6% drift rate by using ABAQUS software. The first connection type is the widely used moment-resisting connection that is defined as a wet connection in the Turkish Seismic Code (TBDY). The second connection type is known as Artificial Controllable Plastic Hinge. The goal of this connection is to defend reinforced concrete components from earthquake-related plastic deformations by keeping them in a specialized connecting section. It will be possible to repair the broken connections after the earthquake. The cyclic behavior of the four types of frames with the mechanical plastic hinge and wet connection was analytically investigated, and then comparisons and suggestions were made on period, ductility, and structural system behavior coefficient. The analytical study shows that the replaceable plastic hinge element provides a significant period increase. Especially in the case of two storeys and two bays, the change in the period was felt the most compared to other frames. The results for ductility show a significant change in the ductility of the frames with replaceable plastic hinges. For the structural system behavior coefficient, a recommendation between 3.90 and 4.52 values was made. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=precast%20structures" title="precast structures">precast structures</a>, <a href="https://publications.waset.org/abstracts/search?q=replaceable%20plastic%20hinge" title=" replaceable plastic hinge"> replaceable plastic hinge</a>, <a href="https://publications.waset.org/abstracts/search?q=beam%20to%20column%20connections" title=" beam to column connections"> beam to column connections</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility" title=" ductility"> ductility</a> </p> <a href="https://publications.waset.org/abstracts/188294/investigation-of-the-ductility-improvement-of-replaceable-hinge-member-on-different-types-of-precast-concrete-frames" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188294.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">48</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">1396</span> Experimental Assessment of Polypropylene Plastic Aggregates(PPA) for Pavement Construction: Their Mechanical Properties via Marshall Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samiullah%20Bhatti">Samiullah Bhatti</a>, <a href="https://publications.waset.org/abstracts/search?q=Safdar%20Abbas%20Zaidi"> Safdar Abbas Zaidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Murtaza%20Ali%20Jafri"> Syed Murtaza Ali Jafri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research paper presents the results of using plastic aggregate in flexible pavement. Plastic aggregates have been prepared with polypropylene (PP) recycled products and have been tested with Marshall apparatus. Grade 60/70 bitumen has been chosen for this research with a total content of 2.5 %, 3 % and 3.5 %. Plastic aggregates are mixed with natural aggregates with different proportions and it ranges from 10 % to 100 % with an increment of 10 %. Therefore, a total of 10 Marshall cakes were prepared with plastic aggregates in addition to a standard pavement sample. In total 33 samples have been tested for Marshall stability, flow and voids in mineral aggregates. The results show an increase in the value when it changes from 2.5 % bitumen to 3 % and after then it goes again toward declination. Thus, 3 % bitumen content has been found as the most optimum value for flexible pavements. Among all the samples, 20 % PP aggregates sample has been found satisfactory with respect to all the standards provided by ASTM. Therefore, it is suggested to use 20 plastic aggregates in flexible pavement construction. A comparison of bearing capacity and skid resistance is also observed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=marshall%20test" title="marshall test">marshall test</a>, <a href="https://publications.waset.org/abstracts/search?q=polypropylene%20plastic" title=" polypropylene plastic"> polypropylene plastic</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20aggregates" title=" plastic aggregates"> plastic aggregates</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20pavement%20alternative" title=" flexible pavement alternative"> flexible pavement alternative</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling%20of%20plastic%20waste" title=" recycling of plastic waste"> recycling of plastic waste</a> </p> <a href="https://publications.waset.org/abstracts/148528/experimental-assessment-of-polypropylene-plastic-aggregatesppa-for-pavement-construction-their-mechanical-properties-via-marshall-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148528.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">143</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">1395</span> Continuous Manufacturing of Ultra Fine Grained Materials by Severe Plastic Deformation Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asl%C4%B1%20G%C3%BCnay%20Bulutsuz">Aslı Günay Bulutsuz</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Emin%20Yurci"> Mehmet Emin Yurci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Severe plastic deformation techniques are top-down deformation methods which enable superior mechanical properties by decreasing grain size. Different kind severe plastic deformation methods have been widely being used at various process temperature and geometries. Besides manufacturing advantages of severe plastic deformation technique, most of the types are being used only at the laboratory level. They cannot be adapted to industrial usage due to their continuous manufacturability and manufacturing costs. In order to enhance these manufacturing difficulties and enable widespread usage, different kinds of methods have been developed. In this review, a comprehensive literature research was fulfilled in order to highlight continuous severe plastic deformation methods. <p class="card-text"><strong>Keywords:</strong> <a
