Abstract:Double-layer spherical reticulated shell roof system was adopted in the main structure of Fujian Provincial Stadium project. An organic glass model in geometrical proportion of 1∶200 to the real structure was constructed to investigate the performance of the spherical reticulated shell system by wind tunnel test. The wind pressures on the inner and outer faces of the model under wind load were measured in wind tunnel to provide available data for structure design. The test results show positive pressures on part of the windward face of the roof. Based on the test results, distribution of wind load was analyzed, which provides data for structure design.

Keywords:double-layer spherical reticulated shell; wind tunnel test; wind load shape coefficient
