Numerical and experiment research on tri-component force coefficient of bridge decks with streamlined section

TONG Pang1,YAO Yong1,YANG Jiong2,LI Xue1(1.Civil Engineering College,Southwest University of Science and Technology,Mianyang 621002,China;2.China Aerodynamics Research and Development Center,Mianyang 621000,China)  
It is able to get the distribution of pressure,velocity and various aerodynamic parameters while researching on the attribution of wind field around the bridge with Computational Fluid Dynamics method.Serevel streamlined section bridge decks with different aerodynamic configuration was used to extract the tri-component force coefficient in different attack angle by CFD method.Compare with the resule of wind tunnel test,the reliability and feasibility of the CFD method is certificated.Meanwhile,accroding to study the change of the pressure and velocity in wind field,the trend of tri-component force coefficient,which influenced by aerodynamic configuration of bridge decks,can be obtained.
