摘要：震害表明，剪力墙结构体系中，剪力墙布置不规范会导致扭转效应过大，从而加重震害。本文采用PKPM建立模型，在保证结构层间位移角基本不变的前提下，通过改变剪力墙厚度、数量以及周边梁的高度，建立不同的模型，对比分析各模型周期、振型、侧移等性能指标,确立了扭转效应小且经济效益好的剪力墙布置方案。

Abstract:The consequences of earthquakes show that the irrational layoutof shear walls would lead to excessivetorsion, thusaggravatingthedisastersin shear-wall structure systems. In the premise ofkeeping the interlayer displacement angle basically unchanged, the structural models were built by the software of PKPMunder different thickness andnumberof the shear walls, and under different height of thenearby beams of the shear walls. Then the performance indexes ofcycle, mode and sideway were compared, and the arrangement of shearwall with less torsionand better economic benefit was established.
