装配式混凝土剪力墙隔震结构地震反应模拟分析

通过建立带有隔震层的装配式高层混凝土剪力墙结构空间有限元模型,对青岛某装配式混凝土剪力墙结构进行隔震设计的有限元非线性分析。用SAP2000对该带有隔震层的结构模拟地震振动响应,与没建立隔震层结构进行层间剪力和剪力比对比分析,并验算隔震支座的水平位移,得出非隔震与隔震结构的层间剪力比范围为2.01~7.45。根据现行抗震规范要求,带有隔震层的装配式结构即使在8度设防烈度下,仍然具有将近2倍的安全储备,隔震技术对于装配式建筑具有良好的抗震性。

SEISMIC RESPONSE SIMULATION ANALYSIS OF PREFABRICATED CONCRETE SHEAR WALL STRUCTURE

The finite element nonlinear analysis of the structure of a prefabricated concrete shear wall in Qingdao by using the finite element model is established.The earthquake simulation vibration responses of the structure with the SAP2000 with isolation layer are done,shear forces and shear ratios are compared with the structure without the isolation layer,and checking the bearings horizontal displacements,layer shear force ratio between the structure without isolation layer and the isolated structure is in the range of 2.01 ～ 7.45.According to the current seismic code requirements,the structure with the isolation layer is in the 8 degree fortification intensity,it still has nearly 2 times safety reserves,it can be seen that the isolation technology for the prefabricated building has good shock resistance to the assembled building.
