This wall is made of a thin steel plate with reinforced a concrete cover, which is attached to one or both sides of the steel plate. This system is similar to stiffened steel plate shear wall, in which reinforced concrete replaces the steel stiffeners. Composite shear wall have in-plane and out-plane significant strength. Also, they have appropriate ductility. The present numerical investigations were focused on the effects of opening on wall mode shapes. In addition, frequencies of composite shear wall with and without opening are compared. For analyzing composite shear wall, a new program will be developed using of finite element theory and the effects of shape, size and position openings on the behavior of composite shear wall will be studied. Results indicated that the existence of opening decreases wall frequency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20shear%20wall" title="composite shear wall">composite shear wall</a>, <a href="https://publications.waset.org/abstracts/search?q=opening" title=" opening"> opening</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=modal%20analysis" title=" modal analysis"> modal analysis</a> </p> <a href="https://publications.waset.org/abstracts/8715/the-effect-of-opening-on-mode-shapes-and-frequencies-of-composite-shear-wall" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8715.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">540</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">4226</span> Application Research on Large Profiled Statues of Steel-Concrete Composite Shear Wall </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhao%20Cai-qi">Zhao Cai-qi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ma%20Jun"> Ma Jun </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Twin steel plates-concrete composite shear walls are composed of a pair of steel plate layers and a concrete layer sandwiched between them, which have the characteristics of both reinforced concrete shear walls and steel plate shear walls. Twin steel plates-composite shear walls contain very high ultimate bearing capacity and ductility, which have great potential to be applied in the super high-rise buildings and special structures. In this paper, we analyzed the basic characteristics and stress mechanism of the twin steel plates-composite shear walls. Specifically, we analyzed the effects of the steel plate thickness, wall thickness and concrete strength on the bearing capacity of the twin steel plates-composite shear walls. The analysis results indicate that：（1）the initial shear stiffness and ultimate shear-carrying capacity is not significantly affected by the thickness of concrete wall but by the class of concrete,（2）both factors significantly impact the shear distribution of the shear walls in ultimate shear-carrying capacity. The technique of twin steel plates-composite shear walls has been successfully applied in the construction of a 88-meter Huge Statue of Buddha located in Hunan Province, China. The analysis results and engineering experiences showed that the twin steel plates-composite shear walls have great potential for future research and applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=twin%20steel%20plates-concrete%20composite%20shear%20wall" title="twin steel plates-concrete composite shear wall">twin steel plates-concrete composite shear wall</a>, <a href="https://publications.waset.org/abstracts/search?q=huge%20statue%20of%20Buddha" title=" huge statue of Buddha"> huge statue of Buddha</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20capacity" title=" shear capacity"> shear capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=initial%20lateral%20stiffness" title=" initial lateral stiffness"> initial lateral stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=overturning%20moment%20bearing" title=" overturning moment bearing"> overturning moment bearing</a> </p> <a href="https://publications.waset.org/abstracts/31153/application-research-on-large-profiled-statues-of-steel-concrete-composite-shear-wall" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31153.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">402</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">4225</span> Strength of the Basement Wall Combined with a Temporary Retaining Wall for Excavation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soo-yeon%20Seo">Soo-yeon Seo</a>, <a href="https://publications.waset.org/abstracts/search?q=Su-jin%20Jung"> Su-jin Jung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, the need for remodeling of many apartments built 30 years ago is increasing. Therefore, researches on the structural reinforcement technology of existing apartments have been conducted. On the other hand, there is a growing need for research on the existing underground space expansion technology to expand the parking space required for remodeling. When expanding an existing underground space, for earthworks, an earth retaining wall must be installed between the existing apartment building and it. In order to maximize the possible underground space, it is necessary to minimize the thickness of the portion of earth retaining wall and underground basement wall. In this manner, the calculation procedure is studied for the evaluation of shear strength of the composite basement wall corresponding to shear span-to-depth ratio in this study. As a result, it was shown that the proposed calculation procedure can be used to evaluate the shear strength of the composite basement wall as safe. On the other hand, when shear span-to-depth ratio is small, shear strength is very underestimated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=underground%20space%20expansion" title="underground space expansion">underground space expansion</a>, <a href="https://publications.waset.org/abstracts/search?q=combined%20structure" title=" combined structure"> combined structure</a>, <a href="https://publications.waset.org/abstracts/search?q=temporary%20retaining%20wall" title=" temporary retaining wall"> temporary retaining wall</a>, <a href="https://publications.waset.org/abstracts/search?q=basement%20wall" title=" basement wall"> basement wall</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20connectors" title=" shear connectors"> shear connectors</a> </p> <a href="https://publications.waset.org/abstracts/86079/strength-of-the-basement-wall-combined-with-a-temporary-retaining-wall-for-excavation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86079.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">4224</span> Seismic Performance Evaluation of the Composite Structural System with Separated Gravity and Lateral Resistant Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zi-Ang%20Li">Zi-Ang Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Mu-Xuan%20Tao"> Mu-Xuan Tao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During the process of the industrialization of steel structure housing, a composite structural system with separated gravity and lateral resistant systems has been applied in engineering practices, which consists of composite frame with hinged beam-column joints, steel brace and RC shear wall. As an attempt in steel structural system area, seismic performance evaluation of the separated composite structure is important for further application in steel housing. This paper focuses on the seismic performance comparison of the separated composite structural system and traditional steel frame-shear wall system under the same inter-story drift ratio (IDR) provision limit. The same architectural layout of a high-rise building is designed as two different structural systems at the same IDR level, and finite element analysis using pushover method is carried out. Static pushover analysis implies that the separated structural system exhibits different lateral deformation mode and failure mechanism with traditional steel frame-shear wall system. Different indexes are adopted and discussed in seismic performance evaluation, including IDR, safe factor (SF), shear wall damage, etc. The performance under maximum considered earthquake (MCE) demand spectrum shows that the shear wall damage of two structural systems are similar; the separated composite structural system exhibits less plastic hinges; and the SF index value of the separated composite structural system is higher than the steel frame shear wall structural system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title="finite element analysis">finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20composite%20structural%20system" title=" new composite structural system"> new composite structural system</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20performance%20evaluation" title=" seismic performance evaluation"> seismic performance evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20pushover%20analysis" title=" static pushover analysis"> static pushover analysis</a> </p> <a href="https://publications.waset.org/abstracts/125678/seismic-performance-evaluation-of-the-composite-structural-system-with-separated-gravity-and-lateral-resistant-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125678.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">136</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">4223</span> Wall Shear Stress Under an Impinging Planar Jet Using the Razor Blade Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Ritcey">A.

Four large-size specimens were tested under displacement-controlled cyclic loading. The design variables considered in the testing program included wall thickness, reinforcement ratio, and faceplate slenderness ratio. The aspect ratio (height-to-length) of the four walls was 1.0. Each SC wall was installed on top of a re-usable foundation block. A bolted baseplate to RC foundation connection was used for all four walls. The walls were identified to be flexure-critical. This paper presents the damage to SC walls at different drift ratios, the cyclic force-displacement relationships, energy dissipation and equivalent viscous damping ratios, the strain and stress fields in the steel faceplates and the contribution of the steel faceplates to the total shear load, the variation of vertical strain in the steel faceplates along the length of the wall, near the base, at different drift ratios, the contributions of shear, flexure, and base rotation to the total lateral displacement, the displacement ductility of the SC walls, and the cyclic secant stiffness of the four SC walls. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=steel-plate%20composite%20shear%20wall" title="steel-plate composite shear wall">steel-plate composite shear wall</a>, <a href="https://publications.waset.org/abstracts/search?q=safety-related%20nuclear%20structure" title=" safety-related nuclear structure"> safety-related nuclear structure</a>, <a href="https://publications.waset.org/abstracts/search?q=flexure-critical%20wall" title=" flexure-critical wall"> flexure-critical wall</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20loading" title=" cyclic loading"> cyclic loading</a> </p> <a href="https://publications.waset.org/abstracts/25770/seismic-response-of-large-scale-rectangular-steel-plate-concrete-composite-shear-walls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25770.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">350</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">4221</span> Experimental Behavior of Composite Shear Walls Having L Shape Steel Sections in Boundary Regions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Bahad%C4%B1r%20Y%C3%BCksel">S.

The study in this paper present the experimental test conducted on CSW having L section folded plate as longitudinal reinforcement in boundary regions. The tested 1/3 geometric scaled CSW has aspect ratio of 3.2. L-shape structural steel materials with 2L-19x57x7mm dimensions were placed in shear wall boundary zones. The seismic behavior of CSW test specimen was investigated by evaluating and interpreting the hysteresis curves, envelope curves, rigidity and consumed energy graphs of this tested element.

The validity of the method is examined through numerical example of 15 storied 3D RC building with shear wall.  This optimization method is expected to assist in providing a useful reference in design early stage, and to be an effective and powerful tool for structural design of RC shear wall structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=structural%20optimization" title="structural optimization">structural optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20static%20analysis" title=" linear static analysis"> linear static analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=ETABS" title=" ETABS"> ETABS</a>, <a href="https://publications.waset.org/abstracts/search?q=MATLAB" title=" MATLAB"> MATLAB</a>, <a href="https://publications.waset.org/abstracts/search?q=RC%20moment%20frame" title=" RC moment frame"> RC moment frame</a>, <a href="https://publications.waset.org/abstracts/search?q=RC%20shear%20wall%20structures" title=" RC shear wall structures"> RC shear wall structures</a> </p> <a href="https://publications.waset.org/abstracts/77143/structural-optimization-method-for-3d-reinforced-concrete-building-structure-with-shear-wall" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77143.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">254</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">4218</span> Time-Dependent Behavior of Damaged Reinforced Concrete Shear Walls Strengthened with Composite Plates Having Variable Fibers Spacing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Redha%20Yeghnem">Redha Yeghnem</a>, <a href="https://publications.waset.org/abstracts/search?q=Laid%20Boulefrakh"> Laid Boulefrakh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sid%20Ahmed%20Meftah"> Sid Ahmed Meftah</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelouahed%20Tounsi"> Abdelouahed Tounsi</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Abbas%20Adda%20Bedia"> El Abbas Adda Bedia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the time-dependent behavior of damaged reinforced concrete shear wall structures strengthened with composite plates having variable fibers spacing was investigated to analyze their seismic response. In the analytical formulation, the adherent and the adhesive layers are all modeled as shear walls, using the mixed finite element method (FEM). The anisotropic damage model is adopted to describe the damage extent of the RC shear walls. The phenomenon of creep and shrinkage of concrete has been determined by Eurocode 2. Large earthquakes recorded in Algeria (El-Asnam and Boumerdes) have been tested to demonstrate the accuracy of the proposed method. Numerical results are obtained for non uniform distributions of carbon fibers in epoxy matrices. The effects of damage extent and the delay mechanism creep and shrinkage of concrete are highlighted.

To enhance the structural integrity, mechanical interlocking or frictional interlocking was introduced. The role of mechanical interlocking or frictional interlocking is to increase the longitudinal shear between the profiled sheet and concrete. This paper deals with the experimental evaluation of three types of mechanical interlocking devices namely normal stud shear connector, J-Type shear connector, U-Type shear connector. An attempt was made to evolve the shear connector which can be suitable for the composite slab as an interlocking device. Totally six number of composite slabs have been experimented with three types of shear connectors and comparison study is made. The outcome was compared with numerical model was created by ABAQUS software and analyzed for comparative purpose. The result was U-Type shear connector provided better performance and resistance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20slabs" title="composite slabs">composite slabs</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20connector" title=" shear connector"> shear connector</a>, <a href="https://publications.waset.org/abstracts/search?q=end%20slip" title=" end slip"> end slip</a>, <a href="https://publications.waset.org/abstracts/search?q=longitudinal%20shear" title=" longitudinal shear"> longitudinal shear</a> </p> <a href="https://publications.waset.org/abstracts/36220/comparative-study-on-different-type-of-shear-connectors-in-composite-slabs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36220.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">326</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">4216</span> Numerical Analysis on the Effect of Abrasive Parameters on Wall Shear Stress and Jet Exit Kinetic Energy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20Deepak">D.

The quality of machined surface depends on jet exit kinetic energy which depends on various operating and material parameters. In the present work the effect abrasive parameters such as its size, concentration and type on jet kinetic energy is investigated using computational fluid dynamics (CFD). In addition, the effect of these parameters on wall shear stress developed inside the nozzle is also investigated. It is found that for the same operating parameters, increase in the abrasive volume fraction (concentration) results in significant decrease in the wall shear stress as well as the jet exit kinetic energy. Increase in the abrasive particle size results in marginal decrease in the jet exit kinetic energy. Numerical simulation also indicates that garnet abrasives produce better jet exit kinetic energy than aluminium oxide and silicon carbide. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abrasive%20water%20jet%20machining" title="abrasive water jet machining">abrasive water jet machining</a>, <a href="https://publications.waset.org/abstracts/search?q=jet%20kinetic%20energy" title=" jet kinetic energy"> jet kinetic energy</a>, <a href="https://publications.waset.org/abstracts/search?q=operating%20pressure" title=" operating pressure"> operating pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=wall%20shear%20stress" title=" wall shear stress"> wall shear stress</a>, <a href="https://publications.waset.org/abstracts/search?q=Garnet%20abrasive" title=" Garnet abrasive"> Garnet abrasive</a> </p> <a href="https://publications.waset.org/abstracts/27545/numerical-analysis-on-the-effect-of-abrasive-parameters-on-wall-shear-stress-and-jet-exit-kinetic-energy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27545.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">377</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">4215</span> Effects of Directivity and Fling Step on Buildings Equipped with J-Hook Sandwich Composite Walls and Reinforced Concrete Shear Walls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Majid%20Saaly">Majid Saaly</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahriar%20Tavousi%20Tafreshi"> Shahriar Tavousi Tafreshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Nazari%20Afshar"> Mehdi Nazari Afshar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The structural systems with the sandwich composite wall (SCSSC) are of very popular due to their ductileness and competency to swallow more energy and power than standard reinforced concrete shear walls. The purpose of this enhanced system is in high-rise building, Nuclear power plant facilities, and bridge slabs are much more. SCSSCs showed acceptable seismic performance under experimental tests and cyclic loading from the points of view of in-plane and out-of-plane shear and flexural interaction, in-plane punching shear, and compressive behavior. The use of sandwich composite walls with J-hook connectors has a significant effect on energy dissipation and reduction of dynamic responses of mid-rise and high-rise structural models.

Thus, it is of great significance to evaluate the seismic demands of the RC shear walls. In this paper, the application of the extend spectrum-based pushover analysis (ESPA) method on the seismic evaluation of the shear wall structure is presented. The ESPA method includes a nonlinear consecutive pushover analysis procedure and a linear elastic modal response analysis procedure to consider the combination of modes in both elastic and inelastic cases.

It is known that shear buckling load of a large span composite beam is difficult to determine experimentally. In order to sensitively detect shear buckling of the tested I-section, twenty strain rosettes and eight displacement sensors were applied and attached on the web and flange surfaces. The tested specimen was a pultruded composite beam made of vinylester resin, E-glass, carbon fibers and micro-fillers. Various coupon tests were performed before the shear buckling test to obtain fundamental material properties of the I-section. An asymmetric four-point bending loading scheme was utilized for the shear test. The loading scheme resulted a high shear and almost zeros moment condition at the center of the web panel. The shear buckling load was successfully determined after analyzing the obtained test data from strain rosettes and displacement sensors. An analytical approach was also performed to verify the experimental results and to support the discussed experimental program. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=strain%20sensor" title="strain sensor">strain sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=displacement%20sensor" title=" displacement sensor"> displacement sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20buckling" title=" shear buckling"> shear buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20composite%20I-section" title=" polymer composite I-section"> polymer composite I-section</a>, <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20loading" title=" asymmetric loading"> asymmetric loading</a> </p> <a href="https://publications.waset.org/abstracts/23154/shear-buckling-of-a-large-pultruded-composite-i-section-under-asymmetric-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23154.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">452</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">4211</span> Semi Empirical Equations for Peak Shear Strength of Rectangular Reinforced Concrete Walls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Kezmane">Ali Kezmane</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Boukais"> Said Boukais</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohand%20Hamizi"> Mohand Hamizi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an analytical study on the behavior of reinforced concrete walls with rectangular cross section.

Subsequently, nominal shear wall strengths from the formulas were compared with the ultimate shear wall strengths from the database. These formulas vary substantially in functional form and do not account for all variables that affect the response of walls.

It also performs as formwork for concreting and better ceiling surface. The major type of failure occurring in composite slab is shear failure. When the composite slab is flexurally loaded, the longitudinal shear is generated and transferred to the steel sheet concrete interface. When the load increases, the interface slip occurs. The slip failure can be resisted by mechanical interface interlock by shear studs. In this paper, the slip failure has been resisted by shear connectors and geometry of the steel sheet alone. The geometry of the sheet is kept constant for all the specimens and the type of shear connectors has been varied. Totally, three types of shear connectors (viz., straight headed, U and J) are bolted to the trapezoidal profile sheet and the concrete is casted over it. After curing, the composite slab is subjected to flexure load and the test results are compared with the numerical results analysed by ABAQUS software. The test result shows that the U-shaped bolted stud has higher flexure strength than the other two types of shear connectors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cold%20formed%20steel%20sheet" title="cold formed steel sheet">cold formed steel sheet</a>, <a href="https://publications.waset.org/abstracts/search?q=headed%20studs" title=" headed studs"> headed studs</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20interlock" title=" mechanical interlock"> mechanical interlock</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20connectors" title=" shear connectors"> shear connectors</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20failure" title=" shear failure"> shear failure</a>, <a href="https://publications.waset.org/abstracts/search?q=slip%20failure" title=" slip failure "> slip failure </a> </p> <a href="https://publications.waset.org/abstracts/24077/experimental-verification-of-different-types-of-shear-connectors-on-composite-slab" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24077.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">555</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">4209</span> Limited Component Evaluation of the Effect of Regular Cavities on the Sheet Metal Element of the Steel Plate Shear Wall</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyyed%20Abbas%20Mojtabavi">Seyyed Abbas Mojtabavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Fatzaneh%20Moghadam"> Mojtaba Fatzaneh Moghadam</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Mahdavi"> Masoud Mahdavi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Steel Metal Shear Wall is one of the most common and widely used energy dissipation systems in structures, which is used today as a damping system due to the increase in the construction of metal structures.

The loading is done as a concentrated load at the upper point of the shear wall on the second floor based on step type buckle. The mesh in the model is applied in two directions of length and width of the shear wall, equal to 0.02 and 0.033, respectively, and the mesh in the models is of sweep type. Finally, it was found that the steel plate shear wall with cavity (CSPSW) compared to the SPSW model, S (Mises), Smax (In-Plane Principal), Smax (In-Plane Principal-ABS), Smax (Min Principal) increased by 53%, 70%, 68% and 43%, respectively. The presence of cavities has led to an increase in the estimated stresses, but their presence has caused critical stresses and critical deformations created to be removed from the inner surface of the shear wall and transferred to the desired sections (regular cavities) which can be suggested as a solution in seismic design and improvement of the structure to transfer possible damage during the earthquake and storm to the desired and pre-designed location in the structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=steel%20plate%20shear%20wall" title="steel plate shear wall">steel plate shear wall</a>, <a href="https://publications.waset.org/abstracts/search?q=abacus%20software" title=" abacus software"> abacus software</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=" title=""></a>, <a href="https://publications.waset.org/abstracts/search?q=boundary%20element" title=" boundary element"> boundary element</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20structural%20improvement" title=" seismic structural improvement"> seismic structural improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=von%20misses%20stress" title=" von misses stress"> von misses stress</a> </p> <a href="https://publications.waset.org/abstracts/126768/limited-component-evaluation-of-the-effect-of-regular-cavities-on-the-sheet-metal-element-of-the-steel-plate-shear-wall" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126768.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">95</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">4208</span> A Study on Performance-Based Design Analysis for Vertical Extension of Apartment Units</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Minsun%20Kim">Minsun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ki-Sun%20Choi"> Ki-Sun Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Jee%20Lee"> Hyun-Jee Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Young-Chan%20You"> Young-Chan You</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is no reinforcement example for the renovation of the vertical and horizontal extension to existing building structures which is a shear wall type in apartment units in Korea. Among these existing structures, the structures which are shear wall type are rare overseas, while Korea has many shear wall apartment units. Recently, in Korea, a few researchers are trying to confirm the possibility of the vertical extension in existing building with shear walls. This study evaluates the possibility of the renovation by applying performance-based seismic design to existing buildings with shear walls in the analysis phase of the structure. In addition, force-based seismic design, used by general structural engineers in Korea, is carried out to compare the amount of reinforcement of walls, which is a main component of wall structure. As a result, we suggest that performance-based design obtains more economical advantages than force-based seismic design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20for%20extension" title="design for extension">design for extension</a>, <a href="https://publications.waset.org/abstracts/search?q=performance-based%20design" title=" performance-based design"> performance-based design</a>, <a href="https://publications.waset.org/abstracts/search?q=remodeling" title=" remodeling"> remodeling</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20wall%20frame" title=" shear wall frame"> shear wall frame</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20analysis" title=" structural analysis"> structural analysis</a> </p> <a href="https://publications.waset.org/abstracts/79730/a-study-on-performance-based-design-analysis-for-vertical-extension-of-apartment-units" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79730.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">225</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4207</span> Non-Linear Static Pushover Analysis of 15 Storied Reinforced Concrete Building Structure with Shear Wall</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Nikzad">Hamid Nikzad</a>, <a href="https://publications.waset.org/abstracts/search?q=Shinta%20Yoshitomi"> Shinta Yoshitomi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, nonlinear static pushover analysis is performed on 15 storied RC building structure with a shear wall to evaluate the seismic performance of the building.

The use of energy dissipation elements in the structure reduces the percentage of seismic forces on the main members of the building (especially the columns). Steel plate shear wall, as one of the most widely used types of energy dissipation element, has evolved today, and regular drilling of its inner plate is one of the common cases. In the present study, using a finite element method, the shear wall of the steel plate is designed as a floor (with dimensions of 447 × 6/246 cm) with Abacus software and in three different modes on which a cyclic load has been applied. The steel shear wall has a horizontal element (beam) with a reduced beam section (RBS). The hole in the interior plate of the models is created in such a way that it has the process of increasing the area, which makes the effect of increasing the surface area of the hole on the seismic performance of the steel shear wall completely clear. In the end, it was found that with increasing the opening level in the steel shear wall (with reduced cross-section beam), total displacement and plastic strain indicators increased, structural capacity and total energy indicators decreased and the Mises Monson stress index did not change much. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=steel%20plate%20shear%20wall%20with%20opening" title="steel plate shear wall with opening">steel plate shear wall with opening</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20loading" title=" cyclic loading"> cyclic loading</a>, <a href="https://publications.waset.org/abstracts/search?q=reduced%20cross-section%20beam" title=" reduced cross-section beam"> reduced cross-section beam</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=Abaqus%20software" title=" Abaqus software"> Abaqus software</a> </p> <a href="https://publications.waset.org/abstracts/127920/evaluation-of-seismic-behavior-of-steel-shear-wall-with-opening-with-hardener-and-beam-with-reduced-cross-section-under-cycle-loading-with-finite-element-analysis-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127920.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">122</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">4205</span> Numerical Evaluation of Shear Strength for Cold-Formed Steel Shear Wall Panel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rouaz%20Idriss">Rouaz Idriss</a>, <a href="https://publications.waset.org/abstracts/search?q=Bourahla%20Nour-Eddine"> Bourahla Nour-Eddine</a>, <a href="https://publications.waset.org/abstracts/search?q=Kahlouche%20Farah"> Kahlouche Farah</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafa%20Sid%20Ali"> Rafa Sid Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The stability of structures made of light-gauge steel depends highly on the contribution of Shear Wall Panel (SWP) systems under horizontal forces due to wind or earthquake loads. Steel plate sheathing is often used with these panels made of cold formed steel (CFS) to improve its shear strength. In order to predict the shear strength resistance, two methods are presented in this paper. In the first method, the steel plate sheathing is modeled with plats strip taking into account only the tension and compression force due to the horizontal load, where both track and stud are modeled according to the geometrical and mechanical characteristics of the specimen used in the experiments. The theoretical background and empirical formulations of this method are presented in this paper. However, the second method is based on a micro modeling of the cold formed steel Shear Wall Panel “CFS-SWP” using Abaqus software. A nonlinear analysis was carried out with an in-plan monotonic load. Finally, the comparison between these two methods shows that the micro modeling with Abaqus gives better prediction of shear resistance of SWP than strips method. However, the latter is easier and less time consuming than the micro modeling method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cold%20formed%20steel%20%27CFS%27" title="cold formed steel 'CFS'">cold formed steel 'CFS'</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20wall%20panel" title=" shear wall panel"> shear wall panel</a>, <a href="https://publications.waset.org/abstracts/search?q=strip%20method" title=" strip method"> strip method</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20elements" title=" finite elements"> finite elements</a> </p> <a href="https://publications.waset.org/abstracts/46456/numerical-evaluation-of-shear-strength-for-cold-formed-steel-shear-wall-panel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46456.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">309</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4204</span> Assessing the Effect of the Position of the Cavities on the Inner Plate of the Steel Shear Wall under Time History Dynamic Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Mahdavi">Masoud Mahdavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Farzaneh%20Moghadam"> Mojtaba Farzaneh Moghadam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The seismic forces caused by the waves created in the depths of the earth during the earthquake hit the structure and cause the building to vibrate<span dir="RTL">.</span> Creating large seismic forces will cause low-strength sections in the structure to suffer extensive surface damage. The use of new steel shear walls in steel structures has caused the strength of the building and its main members (columns) to increase due to the reduction and depreciation of seismic forces during earthquakes. In the present study, an attempt was made to evaluate a type of steel shear wall that has regular holes in the inner sheet by modeling the finite element model with Abacus software. The shear wall of the steel plate, measuring 6000 × 3000 mm (one floor) and 3 mm thickness, was modeled with four different pores with a cross-sectional area. The shear wall was dynamically subjected to a time history of 5 seconds by three accelerators, El Centro, Imperial Valley and Kobe. The results showed that increasing the distance between the geometric center of the hole and the geometric center of the inner plate in the steel shear wall (increasing the R<sub>CS</sub> index) caused the total maximum acceleration to be transferred from the perimeter of the hole to horizontal and vertical beams. The results also show that there is no direct relationship between R<sub>CS</sub> index and total acceleration in steel shear wall and R<sub>CS</sub> index is separate from the peak ground acceleration value of earthquake. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hollow%20steel%20plate%20shear%20wall" title="hollow steel plate shear wall">hollow steel plate shear wall</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20history%20analysis" title=" time history analysis"> time history analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=abaqus%20software" title=" abaqus software"> abaqus software</a> </p> <a href="https://publications.waset.org/abstracts/127716/assessing-the-effect-of-the-position-of-the-cavities-on-the-inner-plate-of-the-steel-shear-wall-under-time-history-dynamic-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127716.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">102</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">4203</span> Comparative Safety Performance Evaluation of Profiled Deck Composite Slab from the Use of Slope-Intercept and Partial Shear Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Izian%20Abd.%20Karim">Izian Abd.

Beside these, albeit factors such as shear span length, deck geometries and mechanical frictions greatly influence the longitudinal shear strength, that determines the ultimate strength of profiled deck composite slab, and number of methods available for its determination; partial shear and slope-intercept are the two methods according to Euro-code 4 provision. However, the complexity associated with shear behavior of profiled deck composite slab, the use of these methods in determining the load carrying capacities of such slab yields different and conflicting values.

An experimental study of the cyclic nonlinear behavior of SC walls in the NEES laboratory at the University at Buffalo used a connection detail involving the post-tensioning of a steel baseplate to the SC wall to a RC foundation. This type of connection introduces flexibility that influenced substantially the global response of the SC walls. The assumption of a rigid base, which would be commonly made by practitioners, would lead to a substantial overestimation of initial stiffness. This paper presents an analytical approach to characterize the rotational flexibility and to predict the initial stiffness of flexure-critical SC wall piers with baseplate connection. The good agreement between the analytical and test results confirmed the utility of the proposed method for calculating the initial stiffness of an SC wall with baseplate connection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=steel-plate%20composite%20shear%20wall" title="steel-plate composite shear wall">steel-plate composite shear wall</a>, <a href="https://publications.waset.org/abstracts/search?q=flexure-critical%20wall" title="flexure-critical wall">flexure-critical wall</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20loading" title=" cyclic loading"> cyclic loading</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20model" title=" analytical model"> analytical model</a> </p> <a href="https://publications.waset.org/abstracts/25769/a-numerical-study-on-the-connection-of-an-sc-wall-to-an-rc-foundation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25769.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">340</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">4200</span> Design Application Procedures of 15 Storied 3D Reinforced Concrete Shear Wall-Frame Structure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Nikzad">H.

This study highlights the importance of strategically placing shear walls and optimizing the shear wall-to-floor area ratio in building design. Nonlinear analyses were conducted on an eight-story building situated in a high seismic zone, exploring various scenarios of shear wall positioning and ratios to floor area. Employing the performance-based seismic design (PBSD) approach, the study aims to meet acceptance criteria such as inter-story drift ratio and damage levels. The results indicate that concentrating shear walls in the middle of the structure during the design phase yields superior performance compared to peripheral distributions. Utilizing shear walls that fully infill the frame and adopting compound shapes (e.g., Box, U, and L) enhances reliability in terms of inter-story drift. Conversely, the absence of complete shear walls within the frame leads to decreased stiffness and degradation of shorter beams. Increasing the shear wall-to-floor area ratio in building design enhances structural rigidity and reliability regarding inter-story drift, facilitating the attainment of desired performance levels. The study suggests that a shear wall ratio of 1.0% is necessary to meet validation criteria for inter-story drift and structural damage, as exceeding this percentage leads to excessive performance levels, proving uneconomical as structural elements operate near the elastic range. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20analyses" title="nonlinear analyses">nonlinear analyses</a>, <a href="https://publications.waset.org/abstracts/search?q=pushover%20analysis" title=" pushover analysis"> pushover analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20wall" title=" shear wall"> shear wall</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20hinge" title=" plastic hinge"> plastic hinge</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20level" title=" performance level"> performance level</a> </p> <a href="https://publications.waset.org/abstracts/182474/strategic-shear-wall-arrangement-in-buildings-under-seismic-loads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182474.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">50</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">4198</span> Application of Shape Memory Alloy as Shear Connector in Composite Bridges: Overview of State-of-the-Art</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Apurwa%20Rastogi">Apurwa Rastogi</a>, <a href="https://publications.waset.org/abstracts/search?q=Anant%20Parghi"> Anant Parghi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Shape memory alloys (SMAs) are memory metals with a high calibre to outperform as a civil construction material. They showcase novel functionality of undergoing large deformations and self-healing capability (pseudoelasticity) that leads to its emerging applications in a variety of areas. In the existing literature, most of the studies focused on the behaviour of SMA when used in critical regions of the smart buildings/bridges designed to withstand severe earthquakes without collapse and also its various applications in retrofitting works. However, despite having high ductility, their uses as construction joints and shear connectors in composite bridges are still unexplored in the research domain. This article presents to gain a broad outlook on whether SMAs can be partially used as shear connectors in composite bridges. In this regard, existing papers on the characteristics of shear connectors in the composite bridges will be discussed thoroughly and matched with the fundamental characteristics and properties of SMA. Since due to the high strength, stiffness, and ductility phenomena of SMAs, it is expected to be a good material for the shear connectors in composite bridges, and the collected evidence encourages the prior scrutiny of its partial use in the composite constructions. Based on the comprehensive review, important and necessary conclusions will be affirmed, and further emergence of research direction on the use of SMA will be discussed. This opens the window of new possibilities of using smart materials to enhance the performance of bridges even more in the near future. <p class="card-text"><strong>Keywords:</strong> <a
