摘要
在地震作用下,混凝土结构的动力反应(内力和变形等)分析与其恢复力模型直接相关。因此,在试验基础上建立的恢复力模型及其参数是否合理地反应了结构真实的恢复力特性,就必将对结构地震反应分析结果产生显著影响。文章在讨论混凝土结构恢复力模型建立的基础上,运用系统识别方法对恢复力模型参数进行了估计,并用地震模拟振动台实验数据进行了识别检验。
The structures earthquake responses are coherent with their restoring force properties. It is very important to the evaluation of nonlinear structural seismic response whether the restoring model correctly measures the structures′ hysteretic characteristics of seismic action. In this paper,the construction of a restoring model and the identification of the model parameters are studied by random identification method. Based on the shaking table experiments of a 18 storey concrete shear wall model,the seismic responses are calculated with the identified restoring model by time history method and compared with the tested results.
