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 the non-linear numerical analysis model of the multi-ribbed composite plate structure, a multi-ribbed composite plate structure that meets the current code requirements is studied by means of the modal static elasto-plastic analysis method (MPA method) and the elasto-plastic time history analysis method respectively. The finite element simulation and numerical analysis under different earthquake intensities (small earthquakes, medium earthquakes and large earthquakes) are carried out. The results of the two structures are compared based on the results of two methods, including the layer displacement, the floor displacement and the interlaminar shear force. The results show that the modal static elasto-plastic analysis method can be applied to the seismic response of the multi- Displacement Response Analysis and Research.
