摘　　要：为研究地震作用下高层混凝土建筑结构的损伤评估,建立基于最大层间位移角的损伤指标,采用基于易损性曲线的地震损伤评估方法。基于增量动力分析方法得到了巨型框架结构的易损性曲线,进行地震损伤评估。研究结果表明：所采用的地震损伤评估方法能够简单有效地评估巨型框架结构在不同强度地震下的损伤程度,可为巨型框架结构的地震灾害损失评估与修复提供参考依据。To investigate the damage assessment of the high-rise RC building structures under earthquake,a method of vulnerability curves based seismic damage assessment was used,establishing the damage index which was based on the maximum inter-story drift ratios. The vulnerability curves of mega-frame structures were constructed by incremental dynamic analysis for its damage assessment. It is demonstrated that the used method of damage assessment for mega-frame structures is simple in calculation as well as effective in evaluating the damage extent for different seismic intensity indices,and could provide reference for estimating seismic fragility analysis and rehabilitation after earthquake.
