Numerical simulations for aerodynamic derivatives of trestle bridge deck

高架栈桥断面气动导数的数值识别

Using large eddy simulation method to analyze wind flow around trestle bridge deck,and with wavelet power spectrum analysis method,find that influence to the drag coefficient,the lift coefficient and the ten-sional moment coefficient will increase if wave amplitude increasing,and the last two coefficients will be influenced more acutely.

应用大涡模拟分析波浪对某型高架栈桥断面风载的影响,并结合小波功率谱分析,发现随着波浪振幅的增加,栈桥断面的三分力系数受到的影响加大,而且升力系数和扭矩系数比阻力系数对波浪振幅变化更加敏感;3个系数的振幅平均值都随波浪振幅增加而减小。
