摘　　要：为验证文献[1]所提出的非加劲钢板剪力墙简化滞回分析模型的合理性,建立了2个3层单跨非加劲钢板剪力墙算例。以ABAQUS程序所建立的微观有限元模型的分析结果作为基准,采用PERFORM程序建立了2个非加劲钢板剪力墙算例的宏观简化滞回分析模型,进行了四种加载制度下的滞回性能分析,重点对比了两种分析模型在四种加载制度下所获得的滞回曲线、骨架曲线、抗侧刚度及累积滞回耗能。分析结果表明,文献[1]所提出的简化滞回分析模型可较好地预测多层非加劲钢板剪力墙的滞回性能、水平承载力、抗侧刚度及滞回耗能。In order to verify the validity of the unified hysteresis strip model of unstiffened steel plate shear wall,two three-story single-bay steel plate shear wall specimens were established. The micro finite element model analysis results built by ABAQUS were as a reference, and the results of the unified hysteresis strip model built by PERFORM were compared with former results, including the hysteresis curve, skeleton curve, stiffness curve and hysteresis energy dissipation. The results show that the unified hysteresis strip model can accurately predict the static behaviors of multi-story unstiffened steel plate shear wall.
