| 摘 要： | 对轻钢厂房屋面檩条设计计算方法进行分析,认为轻钢厂房在台风中严重破坏的主要原因是设计中重结构轻围护.其次,在现行规范中,低层房屋围护结构的风荷载计算不够统一,以及在高风压地区的一些不合理规定,也是造成钢结构事故的原因.根据轻钢结构在台风中的特性,提出强风下在破坏围护结构的非重要部位形成导风巢的抗风思想.

| Abstract: | The calculation methods of purline in light-weight steel structure is analyzed.According to analysis results,the reasons of the structures damaged badly in typhoon are:(1) extra attention is focused to structure design,but little attention to maintenance structure;(2) in current codes,the values of wind load applying on maintenance structures in low-storied buildings are not identical,and some unreasonable rules for high wind pressure region.According to the property of the light weight steel structures in typhoon,the aerodynamic idea is put forward under the strong wind,in which the nests to lead wind are introduced in the maintenance structures. |

| Keywords: | maintenance structure cold-formed thin-walled shaped steel purline nest to lead wind wind-resist design |
