摘要
本文通过三组钢筋混凝土压弯构件模型的振动台主余震模拟试验和周期性抗震静力试验,初步给出了建立有损伤压弯构件恢复力骨架曲线的一般方法,并在此基础上就不同情况具体给出了随机主余震作用下结构层恢复力骨架曲线的建立步骤,从而为结构在主余震作用下的随机反应分析奠定了基础。最后,通过算例分析,得出了余震对结构破坏的影响。
By way of the cyclic static test and shaking table test of three groups of R.C.compression-flexcure members,the general method for determining the restoring force skeleton curves of damaged members is presented in this paper.In order to provide a foundation for response analysis of structures under random mainshock and aftershocks,the procedures of determining story restoring force skeleton curves after random mainshock and aftershocks have been given under different conditions.Lastly,the effect of aftershocks on the damage of structures has been obtained through the analysis of numerical examples.
