Simulation Analysis on Mechanics of Large-Span Enclosure Steel Structure Used in the Subway Station

This paper has carried out mechanics analysis of plane structure made of steel tube columns and the steel truss girder. Inner force analysis of steel tube column is gotten under vertical and horizontal load by adopting the theoretical calculation method. Using ANSYS software static and modal analysis of the truss girder is performed, and three order natural frequencies and vibration mode are obtained. It is verified for the rationality of the structure. At last the construction of node is given. The structure system has the advantages of simple construction and short cycle, so it can provide valuable reference for similar engineering.
