摘　　要：将顶层空旷多层砌体结构简化为串并朕多质点分析模型 ,利用动力弹塑性时程分析方法对其进行了数值分析。系统地研究了顶层空旷多层砌体结构层数、顶层边墙与中柱刚度比和顶层横墙间距等参数变化时这种结构地震作用的一些变化规律。By resorting to the series-parallel model,a non-linear dynamic time history analysis was carried out to investigate the earthquake resistant performance of the upside-soft multi-story masonry strutures.Several parameters that have significant effects on the seismic responses were studied,such as the story number of the structure,the stiffness ratio of the side wall to the intermediate column,and the spacing interval of cross walls,and some traits of this kind of buildings were discussed.
