底部两层框剪砖房的抗震性能分析

Seismic Behaviour of Multi Story Brick Building with Frame Shear Wall in the Two Botton Floors

采用剪切型串联多质点振动模型分析底部两层框剪砖房的地震反应 ,编制了相应的弹塑性分析程序。在此基础上 ,主要研究了结构频率特性 ,影响房屋抗震性能的主要因素、相邻层间侧移刚度比的合理取值及 8层底部两层框剪砖房在 7度区和 8度区是否有足够的抗震性能。

A shear vibrational model applied assemblage of multiple particles is proposed for the seismic response analysis of masonry building with R/C frame wall in the two bottom floors.On the basis of analyses,some problems are discussed,these mainly are:dynamic properties,main factors that have influence on seismic behavior,earthquake resistant reliability of this building under strong earthquake and the rational ratios of lateral rigidity.[WT5HZ]
