摘　　要：采用理论分析和数值模拟相结合的方式,提出适用于波形钢板剪力墙弹性分析和弹塑性分析的等效计算模型:基于初始刚度等效原则,提出精细化模型与等效模型初始刚度比的概念,依靠初始刚度比修正等效模型的材料属性,将波形钢板剪力墙弹性等效模型的设计转化为初始刚度比计算公式的设计;结合数值模拟将波形钢板墙弹塑性等效模型的设计转化为波形钢板剪力墙弹塑性骨架曲线的设计,并拟合出骨架曲线相关参数设计公式,给出波形钢板剪力墙弹塑性等效模型的设计理论。By using the combination of theoretical analysis and numerical simulation,this paper puts forward an equivalent calculation model suitable for elastic and elastic-plastic analysis of corrugated steel plate shear wall:based on the principle of initial stiffness equivalence,the concept of initial stiffness ratio between refined model and equivalent model is proposed,and the material properties of the equivalent model are modified by the initial stiffness ratio.The design of the elastic equivalent model of corrugated steel plate shear wall is transformed into the design of the formula for calculating the initial stiffness ratio.Combined with numerical simulation,the design of elastic-plastic equivalent model of corrugated steel plate wall is transformed into the design of elastic-plastic skeleton curve of corrugated steel plate shear wall,and the design formula of relevant parameters of skeleton curve isfitted.The design theory of elastic-plastic equivalent model of corrugated steel plate shear wall is given.
