Steel plate shear wall (SPSWs) have good ductility, high strength and stiffness, and considerable energy absorption capability. These advantages have been confirmed in experimental and numerical studies. However, despite these advantages, the need for huge columns surrounding the infill plates is the main limitation of SPSWs. Although the high-performance steel plate shear wall (HPSPSW) has solved this shortcoming, there are still some unknowns about this high-performance system. The HPSPSW system is expected to be more economical than other resisting systems due to ease of fabrication, the elimination of complete joint penetration field welds, the elimination of stress transfer from infill plates to main columns, the higher modification factor and no need for huge main columns. A comparison of analysis results of HPSPSW and SPSW systems revealed that the HPSPSW has desirable stiffness, ductility and energy absorption when its length to height ratio is greater than 1.5. In addition, the HPSPSW system had an ultimate lateral strength only 2–5% lower than that of the SPSW. Modification factors were calculated and average values of 6.67 and 8.64 were obtained for the SPSW and HPSPSW systems, respectively. Therefore, a modification factor of 8.5 is suggested for the HPSPSW.

高性能钢板剪力墙抗震性能研究

钢板剪力墙（SPSWs）具有良好的延性、高强度和刚度，以及相当大的能量吸收能力。这些优点已在实验和数值研究中得到证实。然而，尽管有这些优点，填充板周围需要巨大的柱子是 SPSW 的主要限制。尽管高性能钢板剪力墙（HPSPSW）解决了这个缺点，但这个高性能系统仍然存在一些未知数。预计 HPSPSW 系统将比其他抗性系统更经济，因为它易于制造、消除了完整的接头穿透现场焊缝、消除了从填充板到主柱的应力传递、更高的修改系数以及不需要巨大的主柱列。对比HPSPSW和SPSW系统的分析结果表明，HPSPSW在长高比大于1.5时具有理想的刚度、延性和吸能性能。此外，HPSPSW 系统的极限侧向强度仅比 SPSW 低 2-5%。计算了 SPSW 和 HPSPSW 系统的修正系数，平均值分别为 6.67 和 8.64。因此，建议 HPSPSW 的修正系数为 8.5。分别。因此，建议 HPSPSW 的修正系数为 8.5。分别。因此，建议 HPSPSW 的修正系数为 8.5。
