Abstract：
The Steel Roof of Yangzhong Olympic Sports Center contains many plane irregular space truss. This paper examines structure, load combination, structure analysis and calculation. The design software is Midas Gen and MSTCAD. Two software calculation results are compared with each other and complement each other. The results show that: the Roof of strength, stability and structural measures met the regulatory requirements. This paper introduce the Wind tunnel test results, the surface pressure coefficient of wind load is given, which have reference value.
