摘　　要：为研究结构抗震性能因落地剪力墙布置方案不同的影响,通过有限元分析软件SATWE建立三种不同的落地剪力墙方案,运用反应谱法分析了结构自震周期、地震反应力、最大层间位移角以及结构侧向刚度。分析结果表明:在转换层设置高度相同的情况下,三种方案在转换层以下的地震反应力、最大层间位移角以及侧向刚度对比,第三方案的抗震性能最好。这是由于方案三的落地剪力墙在结构的周边布置更加的多、分布也更加均匀,这样方案三就对抗震更加有力。To study the seismic behavior of different effects due to shear wall layout programs, three different shear wall programs by FEM software SATWE are build. Natural cycle, seismic response force, the maximum story drift and the lateral stiffness of the structure are analyzed with the response spectrum method. The results showed that ： in the case of conversion layer setting the same height, through contrast of three programs below the conversion layer the seismic performance of the third scheme is the best. This is because the program has more shear wall in the surrounding arrangement, the distribution is more uniform, so that the third seismic program is more powerful.
