Abstract: The roof of Art&Physical Center in new campus of Suzhou Lida Middle School is a large span steel truss roof structure. The structure array of the project and the calculation comparison of the overall structure models between different design softwares were described. The key part analysis of the truss and its supporting steel reinforced concrete columns were given. Some advices of parameter selection of design software and some typical joint design of truss were given, which could be reference for similar projects.
Keywords: lage span; steel roof, steel truss, overall consolidation; joint design
