Study of Wind Load Disturbance Effect of Half-Arch Large Span Roof
Journal Title: 河南科技大学学报（自然科学版） - Year 2018, Vol 39, Issue 3
Abstract
The wind load on the upper and lower surfaces of the roof of the stadium was studied by using the wind tunnel test of rigid model and the simultaneous pressure measurement of the upper and lower surfaces with a half-moon arched long span roof stadium. By arranging the measuring points on the upper and lower surfaces of the roof, the wind pressure coefficients under different wind directions were obtained. The comprehensive wind pressure on the roof surface was analyzed when the upstream building was affected. The influence of the upstream building on the upper and lower surfaces wind pressure of the stadium was also analyzed. The results show that the wind load on the stadium roof is dominated by the upward wind suction. The positive pressure at the roof windward support is larger, and the maximum wind pressure coefficient is 1. 4. The negative pressure at the cantilever is larger with a maximum of-2. 0. The influence of the upstream building on the roof surface under different wind direction angle is different. The disturbance effect is most obvious under the 60°wind direction angle.
