摘要
为得到构件刚度折减系数,基于等能量准则,提出刚度折减系数的简化取值方法,构建该方法在等效弹性反应谱法中的迭代流程。以8度区Ⅱ类场地的RC框架结构为算例,讨论了反应谱的选取对分析结果的影响,并对比简化的等效弹性反应谱法与动力弹塑性时程分析的结果,验证了该方法对结构位移响应预测的有效性。
In order to obtain the stiffness reduction factor, a simplified value method of the stiffness reduction factor is proposed based on the equal energy criterion. Moreover, the iterative process of the method in the equivalent elastic response spectrum method is constructed. Taking the RC frame structure of class Ⅱ site in Grade 8 area as the research object, the influence of the selection of response spectrum on the analysis results is discussed, and the results of simplified equivalent elastic response spectrum method and dynamic elastic-plastic time history analysis are compared to verify the effectiveness of this method for the prediction of structural displacement response.
