摘要
为研究钢框架内填竖缝RC墙结构(Steel frame with slit RC wall,简称"SRCW")在不同地震水平下的性态指标,结合我国现行抗震规范,对已完成的8榀SRCW试验数据进行了统计分析,基于修正的Park-Ang模型及损伤指数与性态指标的对应关系,提出了以层间位移角表征的SRCW结构的性态指标矩阵。分析结果表明:SRCW结构在显著屈服和倒塌时的层间位移角均值分别为0.63%和2.36%。SRCW结构在正常使用、基本完好、轻微破坏、中等破坏、严重破坏和倒塌状态下的层间位移角限值分别为1/170、1/130、1/100、1/70、1/50和1/40,研究成果可为SRCW结构开展基于性态的抗震设计及地震易损性分析提供参考。
In order to study the performance indexes of steel frame with RC slit wall structure(SRCW)at different earthquake levels,a total of eight SRCW specimens that have been previous finished were analyzed.According to the current seismic design specification,the modified Park-Ang damage model,and the relationship between damage index and performance index,the performance index matrix of SRCW represented by interstory drift ratio has been proposed.The analytical results show that the interstory drift ratios of SRCW at significant yielding and collapse state were 0.63%and 2.36%,respectively.The representing interstrory drift ratios of SRCW at normal occupy,immediately operational,damage control,life safety,collapse prevention,collapse state,were 1/170,1/130,1/100,1/70,1/50,and 1/40,respectively.The current results can provide some useful reference for improving the performance-based seismic design method and conducting the fragility analysis of SRCW structure.
