Numerical simulation of wind pressure distribution and wind environment on the roof of National Stadium of Vietnam

The numerical simulation study of mean wind pressure on the roof of National Stadium of Vietnam was carried out in this paper.The comparison of the coefficient of mean wind pressure on the roof with the results of wind tunnel test in the 60° direction shows that they are consistent with each other.Then the result of turbulence kinetic energy of numerical simulation near the roof in the 90° direction was present,which was used to analyse the rule of distribution of fluctuating wind pressure on the cantilevered roof,and was compared with the root value of fluctuating wind pressure of wind tunnel test.Finally the model of the unilateral roof was built to compare with that with the bilateral roof.The research of wind environment was made to discuss the influence of windward building.
