摘要

运用有限元分析软件SAP2000建立了不同层数的冷弯薄壁型钢结构住宅三维空间整体模型,分析了冷弯薄壁型钢结构住宅在抗震设防烈度为7、8度时的结构响应。结果表明,冷弯薄壁型钢结构整体性较好,层间位移角的峰值符合我国现行规范要求。在8度及以下抗震设防地区,所构建的冷弯薄壁型钢结构住宅体系可建到6层,限制高度为18m。
The three-dimensional space whole model of cold-formed thin-walled steel residential building with different floors was established by using the finite element analysis software SAP2000,the structural response of which was analyzed when the seismic fortification intensities were 7 and 8.The results indicate that the cold-formed thin-walled steel residential building has a well integral behavior and the maximum of story drift angle meets the requirement of the current national criteria;the model of cold-formed thin-walled steel residential building was appropriate to reach the six-storey and the maximum height was 18m at the 8 seismic fortification intensities and below.
