| 摘 要： | 以一中等跨径连续梁桥为研究对象,建立了橡胶支座的滞回特性曲线以及全桥非线性动力分析模型.从太平洋地震工程研究中心(PEER)强震数据库中选取100条地震波,进行了一系列非线性时程分析,得到了橡胶支座的位移反应.根据基于性能的抗震设计思想和地震易损性分析理论,提出了板式橡胶支座4种不同损伤状态损伤指标的确定方法,并由此拟...

| Abstract: | Taking a mid-span continuous bridge as the research subject,the restoring force model of rubber bearing and the dynamical model of nonlinear analysis were established.Also,100 earthquake wave records were chosen from PEER to conduct a series of nonlinear time-history analyses,and the relative displacement responses of rubber bearings were obtained.Based on the principle of Performance-Based Seismic Design and the theory of seismic vulnerability analysis,a method for determining four different damage indexes... |
