摘　　要：通过改变楼板数量,作极限楼板假设,建立了框架—剪力墙结构模型,并采用ABAQUS进行弹塑性时程分析,检测楼板的数量对结构位移、速度、层间位移角等方面的影响,结果表明:楼板对结构的位移影响非常大,楼板对结构的耗能有一定的影响,不宜对楼板进行全层开洞或开大洞处理。By altering the amount of floor slabs,the paper establishes the framework-shearing wall structure with the extreme floor hypothesis,undertakes the elastic-plastic time-history analysis using ABAQUS,checks the influence of the amount of the slabs on the structural displacement,speed,and interlayer displacement angle,and indicates the floor slabs have larger influence on the structural displacement,while they have certain affect on the structural energy consumption,so it can be unfavorable to undertakes the whole-layer opening hole or large hole treatment.
