Open publisher page 0 citations

Abstract

The wind tunnel test and computational fluid dynamics(CFD) numerical simulation are carried out to investigate the wind load on a stadium roof with long span in south Fujian.The wind tunnel test finds out the average wind pressure coefficient and the regional wind pressure coefficient on the stadium roof under the most disadvantageouse wind direction.Meanwhile,the wind load distribution is numerically simulated using shear stress transport(SST) turbulent model based on the CFX 10.0 software platform.The tested wind pressures agree well with the numerical simulation pressures,therefore the accuracy of the numerical simulation is acceptable to calculate the average wind pressure on roof with long span.
