串联隔震结构体系的地震易损性分析

SEISMIC VULNERABILITY ANALYSIS OF SERIES ISOLATED STRUCTURAL SYSTEMS

  • 摘要: 根据串联隔震建筑结构体系的地震可靠度特征,推导了串联隔震结构体系的地震可靠度计算公式,并根据隔震结构的上部结构、隔震层、下部结构的概率地震需求模型,提出了串联隔震结构的地震易损性计算方法。最后,以某典型高层框架-核心筒基础隔震结构为算例,建立了高层隔震结构的有限元模型并进行地震动响应分析,利用已提出的方法对该隔震结构的地震破坏概率进行分析,获得了高层隔震结构整体处于严重破坏状态时的地震易损性曲线,结果表明隔震层的破坏是影响高层隔震结构体系整体地震可靠度的关键因素。

     

    Abstract: According to the seismic reliability characteristics of series isolated building structure systems, the calculation formula for the seismic reliability of series isolated structural systems is derived. In addition, based on the probabilistic seismic demand models of the superstructure, the isolation layer and the substructure of isolated structure, the calculation method of the seismic vulnerability of series isolated structures is put forward. Finally, taking a typical high-rise frame-core wall base-isolated structure as an example, a finite element model of the high-rise isolated structure is built and used to conduct seismic dynamic response analysis. The seismic damage probability of the isolated structure is analyzed by the proposed method, and the seismic vulnerability curves of the high-rise isolated structure are obtained in the state of severe damage. The results show that the failure of the isolation layer is the key factor that affects the integral seismic reliability of high-rise isolated structural systems.
