摘要
基于国内外对钢筋混凝土构件的非线性地震反应分析和破坏过程的研究,借助动力分析软件LSDYNA,针对目前直接法建立钢筋混凝土模型较为复杂的问题,采用间接法便捷地建立了分离式共节点模型;并选用汶川地震中某次余震所监测的水平方向的地震波数据作为加载波,对某典型五层框架结构受震破坏进行了有限元模拟;探讨了结构在受震破坏过程中不同构件的破坏特征及结构的整体破坏倒塌过程,得出了与实际震害情况比较符合的结果。
Based on study of damage process and analysis for nonlinear seismic response of reinforced concrete member at home and abroad,with the LS-DYNA,in order to simplify reinforced concrete model by direct method, a common node separate RC model of a typical RC frame was set up by indirect method. The horizontal directional seismic data of Wenchuan earthquake was initially loaded to investigate the damage characteristic and the failure features of different parts and collapse form of the structure by finite element simulation. The simulation result fitted practical seismic damage features well.
