摘要:
提出了一种基于性能的巨-子结构控制体系的地震易损性分析方法。定义了巨-子结构控制体系的4个极限状态,提出了基于巨-子结构控制体系极限破坏状态确定结构抗震性能水平限值的方法。通过考虑近场与远场地震动的不确定性,采用增量动力分析(IDA)对比分析了传统巨-子结构抗震体系和巨-子结构控制体系在近、远场地震作用下的地震易损性,并得到了两者的易损性曲线,给出了巨-子结构控制体系的破坏概率。所得结果可供地震灾害的巨-子结构控制体系损伤评估参考。
Abstract:
A performance-based seismic vulnerability analysis method of mega-sub structure control system was proposed herein. Four ultimate damage state for mega-sub structure control system were defined, and based on which, a method for determining the limit values of the four performance levels was put forward. Then the performance-based seismic vulnerabilities of the traditional mega-sub anti-seismic structure and mega-sub control structure under near-fault and far-fault earthquake were compared considering the uncertainties of near-fault and far-fault ground motion characteristics using incremental dynamic analysis (IDA). The vulnerability curves of both systems are obtained, and the damage probability of the mega-sub control structure are given. The results may present a reference to seismic damage assessment of mega-sub structure control system.
