Abstract:Zhenze High School Stadium is composed of east part and west part. Span of the east part is 170.7m and its mechanical system is gird structure with angled prestressed cable. Span of the west part is 224.0m and its mechanical system is cantilever grid structure with back prestressed cable. The structure is analyzed by software 3D3S and MIDAS. The steel amount of whole structure can be reduced by adjusting the initial pretensioned value of cables. According to the requests of structural design, static and dynamic performance analysis, buckling analysis and cable break analysis are given. Structure performance of two parts are generalized.

Keywords:steel roof； prestress； grid structure； buckling analysis； cable break analysis
