【摘要】 研究了剪力墙厚度对底层框剪砌体结构抗震性能的影响.采用非线性时程分析方法,对7度区某一底层框剪砌体结构底层剪力墙厚度取值不同时,该建筑在小震、中震、大震下的反应进行分析.结果表明:随着剪力墙厚度的增加,结构的地震反应明显降低.进而得出初步结论:增大剪力墙厚度实质上是提高了底层框剪层的侧向刚度,但剪力墙厚度不宜过大;过渡层易成为薄弱层.更多还原

【Abstract】 This paper studies the effects of shear-wall thickness on anti-seismic performance of masonry buildings with frame-shear walls at the first floor.Using a nonlinear time-history analysis method it analyzes the response of some masonry buildings with frame-shear walls at the first floor in 7.0 seismic zone under different earthquake scales when the shear-wall thickness varies.The results show that the seismic response of the building structure reduces as the shear-wall thickness increases.In fact the increase of the shear-wall thickness enhances the lateral stiffness of the bottom frame-shear layer,however the shear-wall thickness should not be oversize,if not the transition layer will gets weaker.更多还原
