底层框架—抗震墙砖房抗震性能研究

Study on bottom frame-the seismic performance of earthquake-resistant brick masonry building

通过对结构进行静力弹塑性分析,研究了底层设置不同数量抗震墙对结构薄弱楼层位置和整体结构抗震能力的影响,提出了应合理设置底层抗震墙的数量,使这类结构的底层与第二层的承载力尽量均匀。

Through the analysis on structure static pushover performance,it studies the impacts of different number of shock-resistant walls at the bottom to structurally weak floor location and the overall structure seismic capacity,holds that the number of bottom shock-resistant walls should be set reasonably,so that the bearing capacity of the bottom of these structures could be as even as the bearing capacity of the second layer.
