Abstract

Based on the CFD method, the numerical analysis of the box girder of Gulongshan Bridge is carried out.The static wind coefficient of the bridge box girder under different working conditions is extracted,The influence of the static wind coefficient on the wind speed, the angle of attack and the beam height is analyzed, and the variation characteristics of the flow field of the box girder under various working conditions are analyzed.The results show that the influence of wind speed, angle of attack and beam height on the lift coefficient of beam section is larger, the resistance coefficient is second, and the influence of moment coefficient is not significant. As the height of the box girder increases, the flow field becomes more complex.
