建筑平面为L形的结构,由于其几何形状的不对称性,其剪力墙的合理布置一直是工程设计中的难点,在高烈度区更是如此.本文以平面L形框架-剪力墙结构为研究对象,通过分析软件PKPM和ETABS对所设计的结构进行建模及分析,讨论剪力墙的位置、数量和长度等对结构抗震性能的影响.计算结果表明:综合考虑剪力墙对结构扭转效应和剪力墙自身内力的控制,是进行平面L型框架-剪力墙结构剪力墙布置的先决条件,对结构设计具有重要意义.%Because of asymmetric flat shapes, the proper arrangement of shear walls in building structures with L-shaped plane is always a difficulty in engineering design, especially in high intensity seismic zone. The article focuses on frame-shear wall structures with L-shaped plane. Models are set up in PKPM and ETABS to study on the influence of location, number and length of shear walls on the structural anti-seismic performance. The results show that the control of torsional effect and internal force of shear walls should be considered comprehensively, its prerequisites for layouting of shear walls in the structure with L-shaped plane, which has great significance to structural design.
