结合工程实例，介绍了屋顶钢结构的设计荷载及设计条件，采用SAP2000钢结构设计分析软件，从结构设计应力比与节点位移两方面，进行了结构整体静力分析和构件验算，结果表明该结构侧向刚度大，受力合理，能满足正常使用要求。%Combining with the engineering example,this paper introduced the design load and design condition of roof steel structure,using the SAP2000 steel structure design analysis software,from the structure design force and joint displacement two aspects,made structure overall static analysis and component checking,the results showed that the structure had large lateral stiffness,reasonable force,could meet the requirements of normal use.
