摘　　要：钢筋混凝土剪力墙是高层结构抗震的主要抗侧力构件之一。针对其弹塑性行为的特点,目前已发展了多种微观和宏观分析模型。基于Perforn-3D程序中的纤维墙单元,对3个典型的剪力墙试验构件进行低周反复数值模拟,并对材料的本构和建模参数进行了详细的讨论。计算结果表明,该分析方法能够较好地从宏观角度模拟剪力墙的弹塑性行为,适用于高层建筑结构的整体弹塑性分析和抗震性能评估。Reinforced concrete shear wall is one of the main components in high-rise buildings to resist lateral loads induced by earthquakes. In order to simulate the nonlinear behavior of shear walls, various analytical microscopic and macroscopic models were developed. Three shear wall specimens in low-cyclic loading tests were chosen as research objects and modeled using the fiber shear wall element in PERFORM-3D. This paper also presented some details on the setting of the nonlinear parameters of the materials. The results indicate that the fiber shear wall element can be used to simulate the macroscopic nonlinear behavior of reinforced concrete shear walls rather well and it is suitable for the global elasto-plastic analysis and the seismic performance as- sessment of high-rise buildings.
