摘　　要：钢结构因其特有的自重轻、相对刚度大、受力计算分析准确、生产加工方便等优势而被广泛应用在大型建筑和重要的结构部位。钢桁架是钢结构中一个重要构件之一,特别适用于跨度或高度较大的结构,如桥梁和大跨度屋盖结构等。本工程合理地采用钢桁架做悬挑长度为12 m雨篷的受力构件,并进行两种结构方案的受力分析比较,选择了安全、受力合理的结构方案,希望能给广大设计同仁带来裨益。Steel structure with light weight, relative stiffness, mechanical calculation of accuracy, convenience and other advantages of production and processing has been widely used in large construction and major structural parts. Steel truss is an important component of steel,Especially for the larger span or a high degree of structure, Such as bridges and large span roof structures. This building reasonably made of steel truss cantilever length of 12 m awning the force components,And two structural forms of stress analysis for comparison, Select a safe, reasonable force structure plan, Colleagues hope to give benefit of the general design.
