“…In this state, all the infill panels fully yield through the entire height of the SPSW and plastic hinges form at all HBEs and the bottom VBEs. Based on past pseudo‐dynamic test results, low‐rise SPSWs reach State‐UY when they were subjected to the design basis earthquake with a 10/50 hazard level. Target Hardening State (State‐HD): State‐HD refers to the state when the SPSW deforms to the target story drift limit for the maximum considered earthquake (MCE) with a 2/50 hazard level. An SPSW must have adequate ductlity to reach the target story drift.…”

Summary This research investigates the seismic behavior and design method for the bottom‐level boundary columns, also called the vertical boundary elements (VBEs), in multi‐story steel plate shear walls (SPSWs). This paper firstly introduces the proposed design method for the bottom‐level VBE for the case when a frame swaying action causes the VBE to bend in single curvature, as is often seen in mid‐ and high‐rise buildings. Two 12‐story (12F) prototype SPSWs were designed using the proposed design method. Two 40%‐scale substructural test specimens representing the first 2.5 stories of the 12F SPSW prototype designs were cyclically tested with the Multi‐Axial Testing System at the Taiwan National Center for Research on Earthquake Engineering in 2013. The test results confirm the effectiveness of the proposed design method in predicting the yielding of the top end of the bottom VBE. In addition, test results show that the lateral torsional buckling of the bottom VBE could occur after the VBE top end yields, indicating that premature top‐end yielding should be prohibited for the bottom VBE before the SPSW develops uniform yielding mechanism under the lateral forces.

“…In the analysis of the finite element method, it is found that the influence of vertical joint precast shear walls on seismic performance is not particularly large, and is very similar to the basic cycle. Therefore, in the design of vertical joints, the shear capacity should be fully analyzed [5].…”

Abstract. In order to improve the concept of energy saving and emission reduction, and further promote the development of residential industrialization, the research of prefabricated shear wall structure has become a hot topic. This paper mainly analyzes the development of prefabricated wallboard structure, analysis of components and joints and joints of precast concrete shear wall structure connection, analysis of relevant research results at home and abroad in recent years, the seismic performance of joints, etc. combined with the shear wall are summarized. In this paper, the existing problems of prefabricated shear wall structure and seismic design are discussed, and the solutions and future research directions are pointed out.

Summary The steel plate shear wall (SPSW) is an effective lateral force resisting system in which unstiffened steel infill plates are connected to the horizontal and vertical boundary elements (VBEs) on all sides of the plates. The boundary elements must be designed to resist the tension field force of the infill panels. When the VBEs are made from a steel box section, the flange of each box VBE connected with the infill panels can be pulled out‐of‐plane by significant panel forces, called pull‐out action. This study investigates capacity design methods for box VBEs in SPSWs. Simplified fixed beam and portal frame models aim to estimate the pull‐out responses of the flange of the box sections with and without infill concrete, respectively. In this study, cyclic tests of three full‐scale two‐story SPSWs using box VBEs with or without the infill concrete are conducted. Inelastic pushover analyses of the finite element models are conducted. The tests and analytical results confirm that the proposed design methods, which aimed to prevent the full yield of the flange under the pull‐out action, are applicable. Furthermore, the test and analytical results suggest that the initial yielding of the flange of box VBEs under the collective effects of the pull‐out action on the flange, the gravity load, and the sway action on the SPSW represents a local yielding. A strict prohibition of the initial yielding on the flange under the aforementioned collective effects is not recommended for pursuing a cost‐effective design.
