EXPERIMENTAL STUDY ON WIND LOAD DISTRIBUTION OF OVERHANGING CANOPY OF OVAL STADIUM

A large-span stadium light-shed is often sensitive to wind loading, and wind loading is one of the control loads for such structural design. In order to meet the needs of engineering design and experimental research, a rigid model pressure test for a complex gymnasium is carried out through the calculation and analysis for the shape factor distribution under different wind angles of surface structure, considering the influence of wind directions on the wind load shape coefficient. The results show that the most areas at the top of the canopy are negative pressure, and the wave shape at the top has obvious influence on the wind pressure distribution. At the same time, the maximum wind sensitive area and the maximum wind suction value of the enclosure structure are analyzed, which provides an important basis for the wind resistant design of the structure.
