摘要
本文对相似比为1:4的三组钢筋混凝土压弯构件模型先后进行了振动台主余震模拟试验和周期性抗震静力试验,通过试验研究了钢筋混凝土压弯构件在主余震作用下的反应与损伤特性,并首次探讨了有损伤压弯构件恢复力模型的特点,在此基础上给出了建立有损伤压弯构件恢复力骨架曲线的一般方法,从而为结构在主余震作用下的随机地震反应分析和有损伤结构的抗震加固奠定了基础。
In this paper,the cyclic aseismic static test and the shaking table test that simulating a couple of mainshocks and aftershocks have been respectively made for three groups of 1/4 models of R. C. compression -flexure members. Then,based on the above experiments,the characteristics of response and damage of R. C. compression -flexure members under main-shock and aftershocks are discussed,and the restoring force properties of damaged members are studied. In the end,the general method of determining the skeleton -curve of restoring force of damaged compression -flexure member is also presented. The research of this paper provides a foundation for response analysis of structures under random mainshock and aftershocks.
