The thin unstiffened steel plate shear wall (SPSW) system has now emerged as a promising lateral load resisting system. Considering performance-based design requirements, a ductility-based design was recently proposed for SPSW systems. It was felt that a detailed and closer look into the aspect of seismic lateral force distribution was necessary in this method. An investigation toward finding a suitable lateral force distribution for ductility-based design of SPSW is presented in this paper. The investigation is based on trial designs for a variety of scenarios where five common lateral force distributions are considered. The effectiveness of an assumed trial distribution is measured primarily on the basis of how closely the design achieves the target ductility ratio, which is measured in terms of the roof displacement. All trial distributions are found to be almost equally effective. Therefore, the use of any commonly adopted lateral force distribution is recommended for plastic design of SPSW systems.

Composite steel plate shear wall (CSPSW), as a new lateral force resisting structure composed of steel plate and concrete slab, is introduced. CSPSWs can fully display the superiority of the steel plate and concrete. Ductility and energy dissipation capacity of the walls are increased and seismic behavior is improved. Recent seismic research around the word of two kinds of CSPSWs, namely, CSPSW with signal steel plate and CSPSW with double steel plates, is presented and discussed comprehensively. Some existing problems in current research of the walls are also reviewed in this paper.

Shear wall is the main component that resists the lateral force for high-rise buildings. With the rapid development of high-rise buildings, especially the super high-rise buildings, requirements for seismic performance of shear walls have become more sophisticated. This introduction summarizes the commonly used in embedded development and existing problems of steel plate shear wall, which are stiffened steel plate shear wall, non-stiffened steel plate shear wall, composite steel plate shear wall, preventing buckling of steel plate shear wall and low yield point steel plate shear wall.

Unstiffened Steel Plate Shear Walls (SPSWs) are very effective structural systems designed to resist lateral forces. SPSW systems consist of thin web plates infilled within frames of steel horizontal and vertical boundary elements. The thin unstiffened web plates are expected to buckle in shear and to develop diagonal tension field after buckling under the action of horizontal loads. For unstiffened steel plates, buckling in shear occurs in the elastic range at low stress levels. This behaviour provides strength, stiffness and ductility and allows to have an appropriate level of energy dissipation through tension yielding of the web plates. This paper assesses the inelastic structural response and behaviour of Steel Plate Shear Wall systems using both a modified strip model approach and a new simplified strip model for only beam connected SPSWs. Both models are developed with plasticity concentrated elements and the performed analyses include the nonlinear behaviour of strips, also considering the compressive forces effects over the strip model elements. This research indicates fundamental aspects of the seismic performance of Steel Plate Shear Wall systems, such as energy dissipation capacity, panel ductility demand, seismic inter-story drift and design load demands in Vertical Boundary Elements (VBE) and Horizontal Boundary Elements (HBE) of the frame. The results obtained from the use of these models are compared with selected experimental and numerical results to enrich the research conclusions.

Two two-side constraint steel plate shear wall specimens with vertical stiffeners had been tested under low cyclic loading to study its seismic performance through the performance indexes of the Initial stiffness, hysteretic behavior, load-carrying capacity, destruction mechanism and so on. Test showed that as main lateral force resisting members two-side constraint steel plate shear wall with vertical stiffeners had a very superior seismic performance. So it is worth popularizing in the area of high seismic intensity.


For seismic design requirements, the major stress dispersing components for steel plate shear walls (SPSWs) that be resistant against lateral forces are un-hardened plates infilled (webs) that bend for shear then shape the sequence with diagonal tension field actions (TFAs). The tensile load of an infill plate must be resisted through the horizontal boundary elements (HBEs) and the vertical boundary elements (VBEs) surrounding every plates by means with its capacity design point of view. If rigid connections were established for both the HBEs and the VBEs as well as among VBEs even its base (when stated with other SPSW cases), the SPSWs often gain along with moment of resistance from another boundary element with that of its lateral horizontal forces deployed. Appreciating every usefulness by their boundary frame with their overall strength in that model, through their interest as can also occur in any form of optimizing the design of the SPSW, so instead of based for their appearance to this process for the over strength with which this can supply for withstand a defined lateral forces. About the lateral design, many aspects control its reaction to light – frame shear wall: rank the encasing elements, fastener style, fastener position, keep on low tightening system, size as well as the classification with the connected structural boards, existence frame connections, aspect ratio in the wall (height of the wall and length of the wall ratio), with wall attached components. While framing products and fastener forms vary throughout Cold – Formed Steel (CFS) as well as wood – frame shear wall mechanisms, a whole responds for those mechanisms also seem to be relatively equal when they are sufficiently comprehensive to resolve the material centric limit states. The steel plate shear wall (SPSW) arrangement seems to be recognized just like most among any simplest efficient ways for resistance of the lateral forces, specifically through seismic activity, the loads are adapted on the model. This comprises along with one steel plate infilled attached through an enclosed system throughout horizontal beams and vertical columns for the movement of lateral forces to the base of the foundation. Steel plate shear walls (SPSWs) column in mid – rise along with high – rise constructions typically needs an outsized compression capability, because it bear either an axial forces with gravitational forces of lateral forces and imposed by the moment of overturning. In order to ensure the effective usage with steel inward the plate infilled, and even will attain goodness as a whole earthquake output on that wall, that formed tension field need to have relatively consistent, requiring suitable anchoring by effective accompanying members of the frame. The lateral fore on the steel plate shear wall (SPSW) is determined by using American code.

Abstract Shear Plate Shear Wall (SPSW) is a lateral force resisting system that is usually used in high seismic regions. Opening can be accommodated by using coupled steel plate shear wall (CSPSW) where two or more SPSWs are placed adjacently and are connected by coupling beams. Maximum displacement, shear load capacity and energy dissipation are affected by the dimension of the coupling beams. The construction cost of the building can be reduced vastly by optimizing the size of the coupling beams where the capability of CSPSW to resist the earthquake is maximized. Thus, the objective of this study is to determine the behaviour of maximum displacement, shear load capacity and energy dissipation of the CSPSW when the width, depth and length of the coupling beams are varied. Fourteen CSPSW models were analysed by ABAQUS software, where the models were subjected to lateral cyclic loading as accordance to ATC24. Maximum displacement of the CSPSW was not affected by the dimensions of the coupling beams. Shear load capacity was increased as either the width or the depth of the coupling beam was increased, and achieved its maximum value when the length of the coupling beam was 1000 mm. The optimum width, depth and length of the coupling beam to maximize the energy dissipation of the CSPSW models were 200 mm, 1000 mm and 1000 mm, respectively.

Abstract: The models of un-stiffened, cross stiffened and diagonal stiffened are established by the APDL language of ANSYS, then their reliabilities of stochastic finite element are researched. The result shows that, under the equal seismic forces, the reliability of the three models from childhood in order as is the un-stiffened, the cross stiffened and the diagonal stiffened. And the vertical pressure is the most effective factor toward the three models. Recently years, the study about the steel plate shear wall at home and abroad is almost the research [1,2] of experience and hysteretic performance by the theory combined with experiences. Xianzeng Li [3], who discussed the feasibility of thin steel plate shear wall which is used in the seismic area, studied the stress structure feature and seismic feature of the thin steel plate shear wall under the drab and cyclic loads by finite element. The shear performance under one-way load and the hysteretic performance of the diagonal stiffened were researched deeply by Chunhua Cao [4,5], and the result shows that it’s an excellent part of resisting lateral force with full stability lag circle and high security reserve. In this text, the analysis about the reliability of steel plate spear wall is completed.
