( Center for Engineering Design and Research Under the General Equipment Department, Beijing 100028, China)Abstract: This paper explained the torch tower's structural project and technical difficult points of of Beijing Olympic Games. The fight against wind research and design work of the torch tower in the complex wind environment on the "bird nest" roof also were presented. In this paper, the wind tunnel experiments method and result were introduced. According to three-dimensional mechanical analyse result, it presented that the harmful wind mode unit of the torch tower.
Keywords: torch tower; wind tunnel experiments; wind direction; coefficient of pressure; space shell structure
