摘要

采用双线性滞回模型,对橡胶-摩擦并联基础隔震体系进行单质点的弹塑性时程分析,并对拐点的近似处理方法给予介绍,同时给出并联隔震结构的各项耗能计算公式。通过算例,绘制并联隔震结构各项耗能的时程曲线,并给出了隔震效果。
Based on the bilinear hysteretic model, the elastoplastic time_history analysis of the parallel base isolated system is carried out. In which the approximate treatment method at the inflexion point is introduced and the calculating formula of each dissipating energy for the base isolated structure is given. In the engineering example, the time-history curve of each energy component and the isolating effect of parallel base isolated system are also shown.
