摘　　要：舒适度一直是多层冷弯薄壁型钢结构设计的重要组成部分.通过SAP2000对多层冷弯薄壁型钢结构进行舒适度分析发现:SAP建模不仅操作简单且计算耗时短,在基本风压不大于0.3 k N/m2,多层冷弯薄壁型钢结构满足舒适度不大于150 mm/s2设计;增加斜撑后结构加速度下降不明显.Comfort is always an important part in the design of multi-story cold-formed thin-walled steel structures. The analysis of the comfort degree of multi-layer cold-formed thin-walled steel structure through SAP2000 shows that the SAP modeling is not only easy to operate,but its computational time is also short. When the basic wind pressure is not more than 0. 3 k N/m2,and the comfort degree of the multi-storey cold bending thin-walled steel structure is not greater than that of the design 150 mm/s2. The decrease of acceleration is not obvious after the increase of the inclined bracing.
