摘要
基于前期研究开发的密肋复合板结构非线性数值分析模型,分别采用模态静力弹塑性分析方法(MPA方法)和弹塑性时程分析方法,对满足现行规范要求的一个密肋复合板结构进行了不同地震强度(小震、中震和大震)作用下的有限元模拟计算与数值分析。对结构基于两种方法下的层间位移、楼层侧移及层间剪力有限元计算结果进行对比分析,结果表明,模态静力弹塑性分析方法可应用于密肋复合板结构在地震作用下的位移响应分析与研究。
Based on a developed nonlinear numerical analysis model of MRSS,the calculation and analysis under small earthquakes,medium earthquakes and large earthquakes of a MRSS,which was designed according to current related codes and specifications,were completed by using MPA method and elasto-plastic time history method.The comparison and analysis between numerical results of these two methods,were shown that the MPA method can be used in seismic displacement responses predictions of large MRSS under earthquake.
