摘要
为研究钢板剪力墙(SPSW)对多层轻钢结构抗震性能的影响,文章通过运用有限元分析软件SAP2000建立了6层纯框架轻钢结构模型,以此为基础对结构分别布置了薄钢板剪力墙、厚钢板剪力墙、十字加劲薄钢板剪力墙,对比分析了3种结构模型在荷载作用下的自振周期、加速度及其地震响应。结果表明,在高烈度地震作用下,十字加劲薄钢板剪力墙结构综合性能最好,且具有经济性。
In order to study the SPSW affected to seismic behavior of multi layer light steel structures.By use of nonlinear finite element analysis software Sap2000,a 6-layer model of light weight steel frames is established,which are respectively arranged on thin steel plate shear wall,thick steel plate shear wall,thin steel plate shear wall with cross stiffening.The comparison of the vibration period,acceleration and seismic response of the three kinds of structure model in load is carried out.The results show that,under the action of high intensity earthquakes,cross stiffened thin steel plate shear wall structure has good comprehensive performance and economic characteristics.
