摘要
本文引入机械铰概念解释了钢筋混凝土杆件在地震作用下的失效过程,继而建立了以楼层为基本单位的强梁弱柱型框架结构的倒塌分析模型。并将离散单元法的中心算法———动态松弛法运用到结构倒塌分析模型中,成功地模拟了钢筋混凝土框架结构在地震作用下的倒塌全过程反应。
The authors of this article introduce the concept of mechanic hinge to interpret the failure process of RC columns. Further more, the authors establish a collapse analysis model for structures with weak columns and strong beams. By importing the dynamic releasing method, the core algorithm of discrete element method, into the collapse anlysis model, the authors simulate the whole collapse process of a RC frame structure subjected to strong earthquakes.
