The hysteresis behavior of the joints in the frame model was described using a new hysteresis envelope model.

Mohamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A one-half scale of single-bay two-storey RC frame together with foundation beam and mass concrete block is investigated. Moment resisting RC frame was designed using EC8 by including the provision for seismic loading and detailing of its connection. The objective of the experimental work is to determine seismic behaviour RC frame under in-plane lateral cyclic loading using displacement control method. A double actuator is placed at centre of the mass concrete block at top of frame to represent the seismic load. The percentage drifts are starting from ±0.01% until ±2.25% with increment of ±0.25% drift. The ultimate lateral load of 158.48 kN was recorded at +2.25% drift in pushing and -126.09 kN in pulling direction. From the experimental hysteresis loops, the parameters such as lateral strength capacity, stiffness, ductility and equivalent viscous damping can be obtained. RC frame behaves in the elastic manner followed by inelastic behaviour after reaches the yield limit. The ductility value for this type frame is 4 which lies between the limit 3 and 6. Therefore, it is recommended to build this RC frame for moderate seismic regions under Ductility Class Medium (DCM) such as in Sabah, East Malaysia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=single%20bay" title="single bay">single bay</a>, <a href="https://publications.waset.org/abstracts/search?q=moment%20resisting%20RC%20frame" title=" moment resisting RC frame"> moment resisting RC frame</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility%20class%20medium" title=" ductility class medium"> ductility class medium</a>, <a href="https://publications.waset.org/abstracts/search?q=inelastic%20behavior" title=" inelastic behavior"> inelastic behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20load" title=" seismic load"> seismic load</a> </p> <a href="https://publications.waset.org/abstracts/36154/experimental-study-on-single-bay-rc-frame-designed-using-ec8-under-in-plane-cyclic-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36154.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">388</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">1754</span> Contribution of the SidePlate Beam-Column Connections to the Seismic Responses of Special Moment Frames</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G%C3%B6khan%20Y%C3%BCksel">Gökhan Yüksel</a>, <a href="https://publications.waset.org/abstracts/search?q=Serdar%20Ak%C3%A7a"> Serdar Akça</a>, <a href="https://publications.waset.org/abstracts/search?q=%C4%B0lker%20Kalkan"> İlker Kalkan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study is an attempt to demonstrate the significant levels of contribution of the moment-resisting beam-column connections with side plates to the earthquake behavior of special steel moment frames. To this end, the moment-curvature relationships of a regular beam-column connection and its SidePlate counterpart were determined with the help of finite element analyses. The connection stiffness and deformability values from these finite element analyses were used in the linear time-history analyses of an example structural steel frame under three different seismic excitations. The top-story lateral drift, base shear, and overturning moment values in two orthogonal directions were obtained from these time-history analyses and compared to each other. The results revealed the improvements in the system response with the use of SidePlate connections. The paper ends with crucial recommendations for the plan and design of further studies on this very topic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seismic%20detailing" title="seismic detailing">seismic detailing</a>, <a href="https://publications.waset.org/abstracts/search?q=special%20moment%20frame" title=" special moment frame"> special moment frame</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20structures" title=" steel structures"> steel structures</a>, <a href="https://publications.waset.org/abstracts/search?q=beam-column%20connection" title=" beam-column connection"> beam-column connection</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquake-resistant%20design" title=" earthquake-resistant design"> earthquake-resistant design</a> </p> <a href="https://publications.waset.org/abstracts/150106/contribution-of-the-sideplate-beam-column-connections-to-the-seismic-responses-of-special-moment-frames" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150106.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">98</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">1753</span> Evaluation of Response Modification Factors in Moment Resisting Frame Buildings Considering Soil Structure Interaction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Farheen">K.

The seismic design philosophy is incorporated using response modification factor 'R'. Current code based values of 'R' factor does not reflect the SSI problem as it is based on fixed base condition. In this study, the modified values of 'R' factor for moment resisting frame (MRF) considering SSI are evaluated. The response of structure with and without SSI has been compared using equivalent linear static and nonlinear static pushover analyses for 10-storied moment resisting frame building. The building is located in seismic zone 2B situated on different soils with shear wave velocity (Vₛ) of 300m/sec (SD) and 1200m/s (SB). Code based 'R' factor value for building frame system has been taken as 5.5. Soil medium is modelled using identical but mutually independent horizontal and vertical springs. It was found that the modified 'R' factor values have been decreased by 47% and 43% for soil SD and SB respectively as compared to that of code based 'R' factor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buildings" title="buildings">buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=SSI" title=" SSI"> SSI</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20wave%20velocity" title=" shear wave velocity"> shear wave velocity</a>, <a href="https://publications.waset.org/abstracts/search?q=R%20factor" title=" R factor"> R factor</a> </p> <a href="https://publications.waset.org/abstracts/100311/evaluation-of-response-modification-factors-in-moment-resisting-frame-buildings-considering-soil-structure-interaction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100311.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">212</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">1752</span> Enhancing Seismic Performance of Ductile Moment Frames with Delayed Wire-Rope Bracing Using Middle Steel Plate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Babak%20Dizangian">Babak Dizangian</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Reza%20Ghasemi"> Mohammad Reza Ghasemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Akram%20Ghalandari"> Akram Ghalandari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Moment frames have considerable ductility against cyclic lateral loads and displacements; however, if this feature causes the relative displacement to exceed the permissible limit, it can impose unfavorable hysteretic behavior on the frame. Therefore, adding a bracing system with the capability of preserving the capacity of high energy absorption and controlling displacements without a considerable increase in the stiffness is quite important. This paper investigates the retrofitting of a single storey steel moment frame through a delayed wire-rope bracing system using a middle steel plate. In this model, the steel plate lies where the wire ropes meet, and the model geometry is such that the cables are continuously under tension so that they can take the most advantage of the inherent potential they have in tolerating tensile stress. Using the steel plate also reduces the system stiffness considerably compared to cross bracing systems and preserves the ductile frame’s energy absorption capacity. In this research, the software models of delayed wire-rope bracing system have been studied, validated, and compared with other researchers’ laboratory test results. <p class="card-text"><strong>Keywords:</strong> <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=delayed%20wire%20rope%20bracing" title=" delayed wire rope bracing"> delayed wire rope bracing</a>, <a href="https://publications.waset.org/abstracts/search?q=ductile%20moment%20frame" title=" ductile moment frame"> ductile moment frame</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20absorption" title=" energy absorption"> energy absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=hysteresis%20curve" title=" hysteresis curve"> hysteresis curve</a> </p> <a href="https://publications.waset.org/abstracts/69615/enhancing-seismic-performance-of-ductile-moment-frames-with-delayed-wire-rope-bracing-using-middle-steel-plate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69615.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">289</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">1751</span> Optimization of Steel Moment Frame Structures Using Genetic Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Befkin">Mohammad Befkin</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Momtaz"> Alireza Momtaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Structural design is the challenging aspect of every project due to limitations in dimensions, functionality of the structure, and more importantly, the allocated budget for construction. This research study aims to investigate the optimized design for three steel moment frame buildings with different number of stories using genetic algorithm code. The number and length of spans, and height of each floor were constant in all three buildings. The design of structures are carried out according to AISC code within the provisions of plastic design with allowable stress values. Genetic code for optimization is produced using MATLAB program, while buildings modeled in Opensees program and connected to the MATLAB code to perform iterations in optimization steps. In the end designs resulted from genetic algorithm code were compared with the analysis of buildings in ETABS program. The results demonstrated that suggested structural elements by the code utilize their full capacity, indicating the desirable efficiency of produced code. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title="genetic algorithm">genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20analysis" title=" structural analysis"> structural analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20moment%20frame" title=" steel moment frame"> steel moment frame</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20design" title=" structural design"> structural design</a> </p> <a href="https://publications.waset.org/abstracts/166927/optimization-of-steel-moment-frame-structures-using-genetic-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166927.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">118</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">1750</span> Efficient Moment Frame Structure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mircea%20I.%20Pastrav">Mircea I.

Calculation of response reduction factor (R) is done as per the new formulation of response reduction factor (R) given by Applied Technology Council (ATC)-19 which is the product of strength factor (Rs), ductility factor (Rµ) and redundancy factor (RR). The analysis revealed that these three factors affect the actual value of response reduction factor (R) and therefore they must be taken into consideration while determining the appropriate response reduction factor to be used during the seismic design process. The actual values required for determination of response reduction factor (R) is worked out on the basis of pushover curve which is a plot of base shear verses roof displacement. Finally, the calculated values of response reduction factor (R) of reinforced concrete special moment resisting frame (SMRF) with and without shear wall are compared with the codal values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=response%20reduction%20factor" title="response reduction factor">response reduction factor</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility%20ratio" title=" ductility ratio"> ductility ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=base%20shear" title=" base shear"> base shear</a>, <a href="https://publications.waset.org/abstracts/search?q=special%20moment%20resisting%20frames" title=" special moment resisting frames"> special moment resisting frames</a> </p> <a href="https://publications.waset.org/abstracts/1362/response-reduction-factor-for-earthquake-resistant-design-of-special-moment-resisting-frames" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1362.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">487</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">1748</span> Some Trends in Analysis of Two-Way Solid Slabs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reem%20I.%20Al-Ya%27%20Goub">Reem I.

The results of the analyses demonstrate that software programs vary markedly in terms of the information they provide to the structural designer regarding values of the model insertion, stiffness, effective moment of inertia used and specially the moment values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=two-way%20solid%20slabs" title="two-way solid slabs">two-way solid slabs</a>, <a href="https://publications.waset.org/abstracts/search?q=flat%20plate" title=" flat plate"> flat plate</a>, <a href="https://publications.waset.org/abstracts/search?q=flat%20slab%20with%20beams" title=" flat slab with beams"> flat slab with beams</a>, <a href="https://publications.waset.org/abstracts/search?q=flat%20slab%20with%20drop%20panels" title=" flat slab with drop panels"> flat slab with drop panels</a>, <a href="https://publications.waset.org/abstracts/search?q=analysis" title=" analysis"> analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=EFM" title=" EFM"> EFM</a>, <a href="https://publications.waset.org/abstracts/search?q=CEFM" title=" CEFM"> CEFM</a>, <a href="https://publications.waset.org/abstracts/search?q=FEM" title=" FEM"> FEM</a> </p> <a href="https://publications.waset.org/abstracts/9999/some-trends-in-analysis-of-two-way-solid-slabs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9999.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">1747</span> Hybrid Diagrid System for High-Rise Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Saeid%20Tabaee">Seyed Saeid Tabaee</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Afshari"> Mohammad Afshari</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahador%20Ziaeemehr"> Bahador Ziaeemehr</a>, <a href="https://publications.waset.org/abstracts/search?q=Omid%20Bahar"> Omid Bahar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, using modern structural systems with specific capabilities, like Diagrid, is emerging around the world.

The seismic behavior of a residential 6-storey RC frame building, considering and ignoring the effect of masonry, is numerically investigated using response spectrum (RS) analysis. The considered herein building is designed as a moment resisting frame (MRF) system following the Egyptian code (EC) requirements. Two developed models in terms of bare frame and infill walls frame are used in the study. Equivalent diagonal strut methodology is used to represent the behavior of infill walls, whilst the well-known software package ETABS is used for implementing all frame models and performing the analysis. The results of the numerical simulations such as base shear, displacements, and internal forces for the bare frame as well as the infill wall frame are presented in a comparative way. The results of the study indicate that the interaction between infill walls and frames significantly change the responses of buildings during earthquakes compared to the results of bare frame building model. Specifically, the seismic analysis of RC bare frame structure leads to underestimation of base shear and consequently damage or even collapse of buildings may occur under strong shaking. On the other hand, considering infill walls significantly decrease the peak floor displacements and drifts in both X and Y-directions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=masonry%20infill" title="masonry infill">masonry infill</a>, <a href="https://publications.waset.org/abstracts/search?q=bare%20frame" title=" bare frame"> bare frame</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20spectrum" title=" response spectrum"> response spectrum</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20response" title=" seismic response "> seismic response </a> </p> <a href="https://publications.waset.org/abstracts/23577/effect-of-infill-walls-on-response-of-multi-storey-reinforced-concrete-structure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23577.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">403</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">1744</span> Behavior Factors Evaluation for Reinforced Concrete Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Rizwan">Muhammad Rizwan</a>, <a href="https://publications.waset.org/abstracts/search?q=Naveed%20Ahmad"> Naveed Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Akhtar%20Naeem%20Khan"> Akhtar Naeem Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Seismic behavior factors are evaluated for the performance assessment of low rise reinforced concrete RC frame structures based on experimental study of unidirectional dynamic shake table testing of two 1/3rd reduced scaled two storey frames, with a code confirming special moment resisting frame (SMRF) model and a noncompliant model of similar characteristics but built in low strength concrete .The models were subjected to a scaled accelerogram record of 1994 Northridge earthquake to deformed the test models to final collapse stage in order to obtain the structural response parameters.

A high rate of energy absorption during earthquakes is the benefit of using such devices, which results in damage reduction of structural elements specifically columns. The hysteretic damping capacity of energy dissipation devices is the key point that it may adversely complicate analysis and design of such structures. This effect may be generally represented by equivalent viscous damping. The equivalent viscous damping may be obtained from the expected hysteretic behavior under the design or maximum considered displacement of a structure. In this paper, the hysteretic damping coefficient of a steel moment resisting frame (MRF), which its performance is enhanced by a buckling restrained brace (BRB) system has been evaluated. Having the foresight of damping fraction between BRB and MRF is inevitable for seismic design procedures like Direct Displacement-Based Design (DDBD) method. This paper presents an approach to calculate the damping fraction for such systems by carrying out the dynamic nonlinear time history analysis (NTHA) under harmonic loading, which is tuned to the natural frequency of the system. Two steel moment frame structures, one equipped with BRB, and the other without BRB are simultaneously studied. The extensive analysis shows that proportion of each system damping fraction may be calculated by its shear story portion. In this way, the contribution of each BRB in the floors and their general contribution in the structural performance may be clearly recognized, in advance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buckling%20restrained%20brace" title="buckling restrained brace">buckling restrained brace</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20displacement%20based%20design" title=" direct displacement based design"> direct displacement based design</a>, <a href="https://publications.waset.org/abstracts/search?q=dual%20systems" title=" dual systems"> dual systems</a>, <a href="https://publications.waset.org/abstracts/search?q=hysteretic%20damping" title=" hysteretic damping"> hysteretic damping</a>, <a href="https://publications.waset.org/abstracts/search?q=moment%20resisting%20frames" title=" moment resisting frames"> moment resisting frames</a> </p> <a href="https://publications.waset.org/abstracts/28860/estimation-of-hysteretic-damping-in-steel-dual-systems-with-buckling-restrained-brace-and-moment-resisting-frame" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28860.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">434</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">1741</span> An Investigation into the Interaction of Concrete Frames and Infilled Masonry Walls with Emphasis on the Connections</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Fazlollahi">Hamid Fazlollahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Behzad%20Rafezy"> Behzad Rafezy</a>, <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Afshin"> Hassan Afshin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There masonry infill increases the stiffness of reinforced concrete frames, thus increasing the force of the earthquake also the interaction between the frame and infill, which can have devastating effects on structures.

This paper proposes the procedure to estimate seismic fragility curves using an incremental dynamic analysis (IDA) rather than the method adopting a CSM. To achieve the research purpose, this study compares the seismic fragility curves of a 5-story reinforced concrete (RC) moment frame obtained from both methods, an IDA method and a CSM. Both seismic fragility curves are similar in slight and moderate damage states whereas the fragility curve obtained from the IDA method presents less variation (or uncertainties) in extensive and complete damage states. This is due to the fact that the IDA method can properly capture the structural response beyond yielding rather than the CSM and can directly calculate higher mode effects. From these observations, the CSM could overestimate seismic vulnerabilities of the studied structure in extensive or complete damage states. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seismic%20fragility%20curve" title="seismic fragility curve">seismic fragility curve</a>, <a href="https://publications.waset.org/abstracts/search?q=incremental%20dynamic%20analysis" title=" incremental dynamic analysis"> incremental dynamic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=capacity%20spectrum%20method" title=" capacity spectrum method"> capacity spectrum method</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete%20moment%20frame" title=" reinforced concrete moment frame"> reinforced concrete moment frame</a> </p> <a href="https://publications.waset.org/abstracts/21652/seismic-fragility-functions-of-rc-moment-frames-using-incremental-dynamic-analyses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21652.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">422</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">1739</span> A Study on the Failure Modes of Steel Moment Frame in Post-Earthquake Fire Using Coupled Mechanical-Thermal Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Asgari">Ehsan Asgari</a>, <a href="https://publications.waset.org/abstracts/search?q=Meisam%20Afazeli"> Meisam Afazeli</a>, <a href="https://publications.waset.org/abstracts/search?q=Nezhla%20Attarchian"> Nezhla Attarchian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Post-earthquake fire is considered as a major threat in seismic areas. After an earthquake, fire is possible in structures. In this research, the effect of post-earthquake fire on steel moment frames with and without fireproofing coating is investigated. For this purpose, finite element method is employed. For the verification of finite element results, the results of an experimental study carried out by previous researchers are used, and the predicted FE results are compared with the test results, and good agreement is observed. After ensuring the accuracy of the predictions of finite element models, the effect of post-earthquake fire on the frames is investigated taking into account the parameters including the presence or absence of fire protection, frame design assumptions, earthquake type and different fire scenario. Ordinary fire and post-earthquake fire effect on the frames is also studied. The plastic hinges induced by earthquake in the structure are determined in the beam to the column connection and in panel zone. These areas should be accurately considered when providing fireproofing coatings. The results of the study show that the occurrence of fire beside corner columns is the most damaging scenario that results in progressive collapse of structure. It was also concluded that the behavior of structure in fire after a strong ground motion is significantly different from that in a normal fire. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=post%20earthquake%20fire" title="post earthquake fire">post earthquake fire</a>, <a href="https://publications.waset.org/abstracts/search?q=moment%20frame" title=" moment frame"> moment frame</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20simulation" title=" finite element simulation"> finite element simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=coupled%20temperature-displacement%20analysis" title=" coupled temperature-displacement analysis"> coupled temperature-displacement analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20scenario" title=" fire scenario"> fire scenario</a> </p> <a href="https://publications.waset.org/abstracts/98372/a-study-on-the-failure-modes-of-steel-moment-frame-in-post-earthquake-fire-using-coupled-mechanical-thermal-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98372.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">1738</span> An Analytical Study on Rotational Capacity of Beam-Column Joints in Unit Modular Frames</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kyung-Suk%20Choi">Kyung-Suk Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyung-Joon%20Kim"> Hyung-Joon Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Modular structural systems are constructed using a method that they are assembled with prefabricated unit modular frames on-site. This provides a benefit that can significantly reduce building construction time. Their structural design is usually carried out under the assumption that the load-carrying mechanism is similar to that of a traditional steel moment-resisting system. However, both systems are different in terms of beam-column connection details which may strongly influence the lateral structural behavior. Specially, the presence of access holes in a beam-column joint of a unit modular frame could cause undesirable failure during strong earthquakes. Therefore, this study carried out finite element analyses (FEM) of unit modular frames to investigate the cyclic behavior of beam-column joints with the structural influence of access holes. Analysis results show that the unit modular frames present stable cyclic response with large deformation capacities, and their joints are classified into semi-rigid connections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unit%20modular%20frame" title="unit modular frame">unit modular frame</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20moment%20connection" title=" steel moment connection"> steel moment connection</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20analytical%20model" title=" nonlinear analytical model"> nonlinear analytical model</a>, <a href="https://publications.waset.org/abstracts/search?q=moment-rotation%20relation" title=" moment-rotation relation"> moment-rotation relation</a> </p> <a href="https://publications.waset.org/abstracts/21711/an-analytical-study-on-rotational-capacity-of-beam-column-joints-in-unit-modular-frames" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21711.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">619</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">1737</span> Seismic Evaluation of Multi-Plastic Hinge Design Approach on RC Shear Wall-Moment Frame Systems against Near-Field Earthquakes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Tehranizadeh">Mohsen Tehranizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahboobe%20Forghani"> Mahboobe Forghani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The impact of higher modes on the seismic response of dual structural system consist of concrete moment-resisting frame and with RC shear walls is investigated against near-field earthquakes in this paper. a 20 stories reinforced concrete shear wall-special moment frame structure is designed in accordance with ASCE7 requirements and The nonlinear model of the structure was performed on OpenSees platform. Nonlinear time history dynamic analysis with 3 near-field records are performed on them. In order to further understand the structural collapse behavior in the near field, the response of the structure at the moment of collapse especially the formation of plastic hinges is explored. The results revealed that the amplification of moment at top of the wall due to higher modes, the plastic hinge can form in the upper part of wall, even when designed and detailed for plastic hinging at the base only (according to ACI code).on the other hand, shear forces in excess of capacity design values can develop due to the contribution of the higher modes of vibration to dynamic response due to the near field can cause brittle shear or sliding failure modes. The past investigation on shear walls clearly shows the dual-hinge design concept is effective at reducing the effects of the second mode of response. An advantage of the concept is that, when combined with capacity design, it can result in relaxation of special reinforcing detailing in large portions of the wall. In this study, to investigate the implications of multi-design approach, 4 models with varies arrangement of hinge plastics at the base and height of the shear wall are considered. results base on time history analysis showed that the dual or multi plastic hinges approach can be useful in order to control the high moment and shear demand of higher mode effect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=higher%20mode%20effect" title="higher mode effect">higher mode effect</a>, <a href="https://publications.waset.org/abstracts/search?q=Near-field%20earthquake" title=" Near-field earthquake"> Near-field earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20time%20history%20analysis" title=" nonlinear time history analysis"> nonlinear time history analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=multi%20plastic%20hinge%20design" title=" multi plastic hinge design"> multi plastic hinge design</a> </p> <a href="https://publications.waset.org/abstracts/22489/seismic-evaluation-of-multi-plastic-hinge-design-approach-on-rc-shear-wall-moment-frame-systems-against-near-field-earthquakes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22489.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">430</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">1736</span> Experimental Study on Bending and Torsional Strength of Bulk Molding Compound Seat Back Frame Part</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hee%20Yong%20Kang">Hee Yong Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyeon%20Ho%20Shin"> Hyeon Ho Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jung%20Cheol%20Yoo"> Jung Cheol Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Il%20Taek%20Lee"> Il Taek Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung%20Mo%20Yang"> Sung Mo Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lightweight technology using composites is being developed for vehicle seat structures, and its design must meet the safety requirements. According to the Federal Motor Vehicle Safety Standard (FMVSS) 207 seating systems test procedure, the back moment load is applied to the seat back frame structure for the safety evaluation of the vehicle seat. The seat back frame using the composites is divided into three parts: upper part frame, and left- and right-side frame parts following the manufacturing process. When a rear moment load is applied to the seat back frame, the side frame receives the bending load and the torsional load at the same time. This results in the largest loaded strength. Therefore, strength test of the component unit is required. In this study, a component test method based on the FMVSS 207 seating systems test procedure was proposed for the strength analysis of bending load and torsional load of the automotive Bulk Molding Compound (BMC) Seat Back Side Frame. Moreover, strength evaluation according to the carbon band reinforcement was performed. The back-side frame parts of the seat that are applied to the test were manufactured through BMC that is composed of vinyl ester Matrix and short carbon fiber. Then, two kinds of reinforced and non-reinforced parts of carbon band were formed through a high-temperature compression molding process. In addition, the structure that is applied to the component test was constructed by referring to the FMVSS 207. Then, the bending load and the torsional load were applied through the displacement control to perform the strength test for four load conditions. The results of each test are shown through the load-displacement curves of the specimen. The failure strength of the parts caused by the reinforcement of the carbon band was analyzed. Additionally, the fracture characteristics of the parts for four strength tests were evaluated, and the weakness structure of the back-side frame of the seat structure was confirmed according to the test conditions. Through the bending and torsional strength test methods, we confirmed the strength and fracture characteristics of BMC Seat Back Side Frame according to the carbon band reinforcement. And we proposed a method of testing the part strength of a seat back frame for vehicles that can meet the FMVSS 207. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seat%20back%20frame" title="seat back frame">seat back frame</a>, <a href="https://publications.waset.org/abstracts/search?q=bending%20and%20torsional%20strength" title=" bending and torsional strength"> bending and torsional strength</a>, <a href="https://publications.waset.org/abstracts/search?q=BMC%20%28Bulk%20Molding%20Compound%29" title=" BMC (Bulk Molding Compound)"> BMC (Bulk Molding Compound)</a>, <a href="https://publications.waset.org/abstracts/search?q=FMVSS%20207%20seating%20systems" title=" FMVSS 207 seating systems"> FMVSS 207 seating systems</a> </p> <a href="https://publications.waset.org/abstracts/92200/experimental-study-on-bending-and-torsional-strength-of-bulk-molding-compound-seat-back-frame-part" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92200.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">210</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">1735</span> Shaking Force Balancing of Mechanisms: An Overview</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vigen%20Arakelian">Vigen Arakelian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The balancing of mechanisms is a well-known problem in the field of mechanical engineering because the variable dynamic loads cause vibrations, as well as noise, wear and fatigue of the machines. A mechanical system with unbalance shaking force and shaking moment transmits substantial vibration to the frame. Therefore, the objective of the balancing is to cancel or reduce the variable dynamic reactions transmitted to the frame. The resolution of this problem consists in the balancing of the shaking force and shaking moment. It can be fully or partially, by internal mass redistribution via adding counterweights or by modification of the mechanism's architecture via adding auxiliary structures. The balancing problems are of continue interest to researchers. Several laboratories around the world are very active in this area and new results are published regularly. However, despite its ancient history, mechanism balancing theory continues to be developed and new approaches and solutions are constantly being reported. Various surveys have been published that disclose particularities of balancing methods. The author believes that this is an appropriate moment to present a state of the art of the shaking force balancing studies completed by new research results. This paper presents an overview of methods devoted to the shaking force balancing of mechanisms, as well as the historical aspects of the origins and the evolution of the balancing theory of mechanisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inertial%20forces" title="inertial forces">inertial forces</a>, <a href="https://publications.waset.org/abstracts/search?q=shaking%20forces" title=" shaking forces"> shaking forces</a>, <a href="https://publications.waset.org/abstracts/search?q=balancing" title=" balancing"> balancing</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamics" title=" dynamics"> dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanism%20design" title=" mechanism design"> mechanism design</a> </p> <a href="https://publications.waset.org/abstracts/124788/shaking-force-balancing-of-mechanisms-an-overview" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124788.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">127</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">1734</span> Evaluation of Expected Annual Loss Probabilities of RC Moment Resisting Frames</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saemee%20Jun">Saemee Jun</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong-Hyeon%20Shin"> Dong-Hyeon Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae-Sang%20Ahn"> Tae-Sang Ahn</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyung-Joon%20Kim"> Hyung-Joon Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Building loss estimation methodologies which have been advanced considerably in recent decades are usually used to estimate socio and economic impacts resulting from seismic structural damage. In accordance with these methods, this paper presents the evaluation of an annual loss probability of a reinforced concrete moment resisting frame designed according to Korean Building Code. The annual loss probability is defined by (1) a fragility curve obtained from a capacity spectrum method which is similar to a method adopted from HAZUS, and (2) a seismic hazard curve derived from annual frequencies of exceedance per peak ground acceleration. Seismic fragilities are computed to calculate the annual loss probability of a certain structure using functions depending on structural capacity, seismic demand, structural response and the probability of exceeding damage state thresholds. This study carried out a nonlinear static analysis to obtain the capacity of a RC moment resisting frame selected as a prototype building. The analysis results show that the probability of being extensive structural damage in the prototype building is expected to 0.004% in a year. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=expected%20annual%20loss" title="expected annual loss">expected annual loss</a>, <a href="https://publications.waset.org/abstracts/search?q=loss%20estimation" title="loss estimation">loss estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=RC%20structure" title=" RC structure"> RC structure</a>, <a href="https://publications.waset.org/abstracts/search?q=fragility%20analysis" title=" fragility analysis"> fragility analysis</a> </p> <a href="https://publications.waset.org/abstracts/21645/evaluation-of-expected-annual-loss-probabilities-of-rc-moment-resisting-frames" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21645.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">397</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">1733</span> Seismic Response of Belt Truss System in Regular RC Frame Structure at the Different Positions of the Storey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Raish%20Ansari">Mohd Raish Ansari</a>, <a href="https://publications.waset.org/abstracts/search?q=Tauheed%20Alam%20Khan"> Tauheed Alam Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research paper is a comparative study of the belt truss in the Regular RC frame structure at the different positions of the floor.

The new structural seismic behavior assessment methods have been proposed, so it is necessary to define a formulation as a damage index, which the damage amount has been quantified and qualified. In this paper, four new steel moment-resisting frames with intermediate ductility and different height (2, 5, 8, and 12-story) with regular geometry and simple rectangular plan were supposed and designed. The three existing groups’ damage indices were studied, each group consisting of local index (Drift, Maximum Roof Displacement, Banon Failure, Kinematic, Banon Normalized Cumulative Rotation, Cumulative Plastic Rotation and Ductility), global index (Roufaiel and Meyer, Papadopoulos, Sozen, Rosenblueth, Ductility and Base Shear), and story (Banon Failure and Inter-story Rotation). The necessary parameters for these damage indices have been calculated under the effect of far-fault ground motion records by Non-linear Dynamic Time History Analysis. Finally, prioritization of damage indices is defined based on more conservative values in terms of more damageability rate. The results show that the selected damage index has an important effect on estimation of the damage state. Also, failure, drift, and Rosenblueth damage indices are more conservative indices respectively for local, story and global damage indices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damage%20index" title="damage index">damage index</a>, <a href="https://publications.waset.org/abstracts/search?q=far-fault%20ground%20motion%20records" title=" far-fault ground motion records"> far-fault ground motion records</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20time%20history%20analysis" title=" non-linear time history analysis"> non-linear time history analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=SeismoStruct%20software" title=" SeismoStruct software"> SeismoStruct software</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20moment-resisting%20frame" title=" steel moment-resisting frame"> steel moment-resisting frame</a> </p> <a href="https://publications.waset.org/abstracts/93473/comparison-of-the-existing-damage-indices-in-steel-moment-resisting-frame-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93473.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">1731</span> Seismic Performance of Two-Storey RC Frame Designed EC8 under In-Plane Cyclic Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20H.%20Hamid">N.

The prototype model of reinforced concrete frame was constructed in one-half scale tested under in-plane lateral cyclic loading starts with ±0.2% drift, ±0.25% up to ±3.0% drift with the increment of ±0.25%. The performance of the RC frame is evaluated in terms of the hysteresis loop (load vs. displacement), stiffness, ductility, lateral strength, stress-strain relationship and equivalent viscous damping. Visual observation of the crack pattern after testing were observed where the beam- column joint suffer the most severe damage as it is the critical part in moment resisting frame. Spalling of concrete starts occurred at ±2.0% drift and become worse at ±2.5% drift.

In trying to aid in the effort, the research presented in this paper aims to prove the efficiency of modified special hybrid moment frames composed of discretely jointed precast and post-tensioned concrete members. This aim is due to the fact that current design standards do not cover the spatial design of moment frame structures assembled by post-tensioning with special hybrid joints. This lack of standardization is coupled with the fact that previous experimental programs, available in scientific literature, deal mainly with plane structures and offer little information regarding spatial behavior. A spatial model of a modified hybrid moment frame is experimentally analyzed. The experimental results of a natural scale model test of a corner column-beams sub-structure, cut from an actual multilevel building tested to seismic type loading are presented in order to highlight the behavior of this type of structure. The test is performed under alternative cycles of imposed lateral displacements, up to a storey drift ratio of 0.035. Seismic response of the spatial model is discussed considering the acceptance criteria for reinforced concrete frame structures designed based on experimental tests, as well as some of its major sustainability features. The results obtained show an overall excellent behavior of the system. The joint detailing allows for quick and cheap repairs after an accidental event and a self-balancing behavior of the system that ensures it can be used almost immediately after an accidental event it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=modified%20hybrid%20joint" title="modified hybrid joint">modified hybrid joint</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20type%20loading%20response" title=" seismic type loading response"> seismic type loading response</a>, <a href="https://publications.waset.org/abstracts/search?q=self-balancing%20structure" title=" self-balancing structure"> self-balancing structure</a>, <a href="https://publications.waset.org/abstracts/search?q=acceptance%20criteria" title=" acceptance criteria"> acceptance criteria</a> </p> <a href="https://publications.waset.org/abstracts/54920/seismic-behavior-of-self-balancing-post-tensioned-reinforced-concrete-spatial-structure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54920.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">240</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">1729</span> Study on Energy Absorption Characteristic of Cab Frame with FEM</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shigeyuki%20Haruyama">Shigeyuki Haruyama</a>, <a href="https://publications.waset.org/abstracts/search?q=Oke%20Oktavianty"> Oke Oktavianty</a>, <a href="https://publications.waset.org/abstracts/search?q=Zefry%20Darmawan"> Zefry Darmawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Tadayuki%20Kyoutani"> Tadayuki Kyoutani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ken%20Kaminishi"> Ken Kaminishi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cab’s frame strength is considered as an important factor in excavator’s operator safety, especially during roll-over.

Deformation mode and energy absorption's of cab’s frame part are investigated on two conditions, with wrinkle and without wrinkle. The occurrence of wrinkle when deforming cab frame can reduce energy absorption, and among 4 parts with wrinkle, the energy absorption significantly decreases in part C. Residual stress that generated upon the bending process of part C is analyzed to confirm it possibility in increasing the energy absorption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ROPS" title="ROPS">ROPS</a>, <a href="https://publications.waset.org/abstracts/search?q=FEM" title=" FEM"> FEM</a>, <a href="https://publications.waset.org/abstracts/search?q=hydraulic%20excavator" title=" hydraulic excavator"> hydraulic excavator</a>, <a href="https://publications.waset.org/abstracts/search?q=cab%20frame" title=" cab frame"> cab frame</a> </p> <a href="https://publications.waset.org/abstracts/42428/study-on-energy-absorption-characteristic-of-cab-frame-with-fem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42428.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">430</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">1728</span> Effect of Adding Horizontal Steel Bracing System to Ordinary Moment Steel Frames Subjected to Wind Load</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yousef%20Al-Qaryouti">Yousef Al-Qaryouti</a>, <a href="https://publications.waset.org/abstracts/search?q=Besan%20Alagawani"> Besan Alagawani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main concern of this study is to evaluate the effect of adding horizontal steel bracing system to ordinary moment resisting steel frames subjected to wind load. Similar frames without bracing systems are also to be compared. A general analytical study was carried out to obtain the influence of such system in resisting wind load. Linear static analysis has been carried out using ETABS software by applying fixed wind load defined according to ASCE7-10 for three-, six-, nine-, and twelve-story ordinary moment steel frame buildings including and not including horizontal steel bracing system. The results showed that the lateral drift due to wind load decreased by adding horizontal bracing system. Also, the results show that effect of such system is more efficient to low-rise buildings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=horizontal%20bracing%20system" title="horizontal bracing system">horizontal bracing system</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20moment%20frames" title=" steel moment frames"> steel moment frames</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20load%20resisting%20system" title=" wind load resisting system"> wind load resisting system</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20static%20analysis" title=" linear static analysis"> linear static analysis</a> </p> <a href="https://publications.waset.org/abstracts/52051/effect-of-adding-horizontal-steel-bracing-system-to-ordinary-moment-steel-frames-subjected-to-wind-load" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52051.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">287</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">1727</span> Bracing Applications for Improving the Earthquake Performance of Reinforced Concrete Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diyar%20Yousif%20Ali">Diyar Yousif Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Braced frames, besides other structural systems, such as shear walls or moment resisting frames, have been a valuable and effective technique to increase structures against seismic loads. In wind or seismic excitations, diagonal members react as truss web elements which would afford tension or compression stresses. This study proposes to consider the effect of bracing diagonal configuration on values of base shear and displacement of building. Two models were created, and nonlinear pushover analysis was implemented. Results show that bracing members enhance the lateral load performance of the Concentric Braced Frame (CBF) considerably. The purpose of this article is to study the nonlinear response of reinforced concrete structures which contain hollow pipe steel braces as the major structural elements against earthquake loads. A five-storey reinforced concrete structure was selected in this study; two different reinforced concrete frames were considered. The first system was an un-braced frame, while the last one was a braced frame with diagonal bracing. Analytical modelings of the bare frame and braced frame were realized by means of SAP 2000. The performances of all structures were evaluated using nonlinear static analyses. From these analyses, the base shear and displacements were compared. Results are plotted in diagrams and discussed extensively, and the results of the analyses showed that the braced frame was seemed to capable of more lateral load carrying and had a high value for stiffness and lower roof displacement in comparison with the bare frame. <p class="card-text"><strong>Keywords:</strong> <a
