摘　　要：本论文通过调整某框架-剪力墙结构的剪力墙平面布置,运用Sap2000对各平面布置方案进行模态分析,并应用反应谱进行地震作用计算,探讨剪力墙的平面布置对框架-剪力墙结构地震响应的影响,分析发现,改进后的模型的抗震性能显著提高,并且剪力墙布置在离刚心远的位置,抗扭效果较好。说明,在剪力墙数量一定的情况下,合理的剪力墙平面布置可以有效提高框剪结构的抗震性能。Based on adjusting the plane layout of shear wall with a frame-shear wall structure,the modal of each plane layout scheme was analyzed by using Sap2000 and the seismic action was calculated by using response spectrum method.The influence of plane layouts of shear wall on frame-shear wall structure seismic response was investigated.It was found that the seismic performance of the improved model was significantly improved,and the longer the distance of shear walls to the center of rigidity was,the better the torsional effect will be.The reasonable shear wall layout could effectively improve the seismic performance of a frame shear structure.
