Title: Wind load distribution and wind tunnel test for a curved concave long-span roof
Abstract: The wind load distribution on a quadratic concave structure was obtained through pressure measurement and wind tunnel test based on a rigid model.Variations of mean and RMS wind pressure coefficients with different wind velocities and different wind field types were compared and analyzed.The results showed that a strong negative wind pressure appears in the windward edges due to flow separation and the reattachment area are under a stable weak positive pressure;the effect of wind velocity on both wind load distribution and wind pressure coefficients can be neglected;turbulence intensity has a significant effect on wind pressure coefficients,especially,on those in windward edges,therefore,it is necessary to simulate appropriate turbulence intensity according to actual situation in wind load test of similar concave structures.
