【摘要】 为了用振型分解法快速分析防屈曲支撑结构(BRBS)的抗震性能,需将防屈曲支撑(BRB)的恢复力模型进行等效线性化。基于恢复力常用的速度相关型模型和位移相关型模型,以能量法和割线刚度法两种等效线性方法,给出了BRBS振型分解反应谱法的详细计算过程。更多还原

【Abstract】 In order to use the modal decomposition response spectrum method for analysis of buckling-restrained braced structure,the equivalent linearization must be used to the restoring force model of buckling-restrained brace. Based on commonly used the velocity relation model and displacement relation model in the restoring force,and used two kinds of equivalent linearization methods of the energy method and secant method,and gave the detail process of modal decomposition response method for buckling-restrained braced structure.更多还原
