摘要
在结构的整体损伤计算中,加权组合法中的权系数将直接影响加权组合法的计算准确度。为此,本文针对规则的剪切型框架结构提出了一种基于能量和损伤指数的加权组合法,并给出了其权系数的具体表达式,同时通过某工程算例将该方法与常规的加权组合法进行对比分析。结果表明:该方法能够综合考虑楼层的滞回耗能、损伤指数及薄弱层等多方面因素,其计算结果可供工程设计人员参考。
In overall damage calculation for structures,the weight coefficient of the weighted combination method will directly affect the computation accuracy.For this reason,in accordance with the shear-type frame structure,the weighted combination method is proposed on basis of energy and damage index.This method and the conventional method of weighted combination are compared in a project in this paper.The results show that this method can comprehensively consider hysteretic energy,and damage index of each floor,and unsubstantial layer and other factors,which can be used as reference for engineering designers.
