摘　　要：在前人研究成果的基础上,本文通过对6个型钢高性能混凝土剪力墙荷载-位移滞回曲线的分析,得出了简化的三折线型恢复力模型,并提出各个特征参数的计算公式,计算值与与试验值较为吻合。滞回规则采用考虑刚度退化和强度退化的剪切滞变模型,为型钢混凝土剪力墙的弹塑性分析提供了依据。Based on the previous study of other authors,the hysteresis curves of load-displacement of six steel high performance concrete shear walls （SHPCW） were analyzed,simple trilinear resilience model was obtained and reckon formularies of character parameters were proposed.The calculated value in our study shows good agreement with the testing values.The hysteretic shear model with hysteretic rules which can express stiffness degradation and strength degradation,is an essential tool for elastic-plastic analysis of SHPCW.
