The cold-formed steel shear wall with steel sheathing has gained increasing popularity due to its excellent shear capacity. To extend the applicability of this system to multi-story residences, aside from experimental investigations on the shear walls, it is essential to conduct a comprehensive study on the seismic performance of buildings. In this paper, numerical simulations were conducted on specimens subjected to monotonic and cyclic loading. Subsequently, seismic analysis of mid-rise building models was also carried out to investigate the influence of the proposed shear wall on building seismic performance. The research findings indicate that this study's modeling method can effectively simulate the shear performance of the proposed shear wall under monotonic and cyclic loading. In addition, the proposed shear wall significantly enhances the structural stiffness and improves the seismic performance of the structure under seismic action.
带钢面板的冷弯型钢剪力墙因其出色的抗剪能力而越来越受欢迎。为了将该体系的适用性扩展到多层住宅，除了对剪力墙进行试验研究外，对建筑物的抗震性能进行全面研究也至关重要。本文对承受单调和循环加载的试件进行了数值模拟。随后，还对中高层建筑模型进行了地震分析，以研究所提出的剪力墙对建筑物抗震性能的影响。研究结果表明，本研究的建模方法能够有效地模拟所提出的剪力墙在单调和循环加载下的抗剪性能。此外，所提出的剪力墙显著提高了结构刚度，并改善了结构在地震作用下的抗震性能。
