底部两层框架—砼抗震墙,上部五层砖房模型的振动台试验

通过底部两层框架－砼抗震墙、上部五层砖房１／６比例模型的模拟地震振台试验,考察了该结构的水平地震作用下的力学性能,并分析了不同试验阶段模型的动力特性变化规律、地震反应分布规律、薄弱层部位及抗震能力。最后初步提出了这种结构的抗震设计建议。

Shaking table Experiment of Model of Seven-story brick Masonry Building with

Based on the shaking table experiment of model of seven story brick masonry building with frame concrete shear wall structure at first two stories, the mechanical behaviours of this kind of structure are studied. The changing law of the dynamic char acteristics, the distributive law of the seismic response, the location of the weak stories and the aseismic capacity of the model are analysed in different stages. Finally. some suggestions on aseismic design are initally presented.
