摘要
某车站站台雨篷钢结构具有体型及跨度较大、构造复杂,结构分析难度大,存在温度变形和温度应力且结构安全性要求较高等特点。采用有限元软件ANSYS对结构进行模拟分析,模拟了大跨度钢结构雨篷的受力状况和变形,计算了主要构件和节点的稳定性,验算了结构的安全性。通过模拟分析得出结论:该大跨度钢结构雨篷受力合理,结构安全。
The steel canopy of a station platform has the problems of large scale,long span,complicated structure,temperature deformation,temperature stress,and high-level security requirements. It is very difficult to carry out structure analysis. The finite element software ANSYS was used to simulate and analyze the structure,as well as the stress state and deformation of the long-span steel canopy structure. The stability of main components and node were calculated so as to verify the safety of the structure. Through the simulation and analysis,the results showed that the long-span steel canopy had reasonable stress and safety structure.
