| Abstract: | Based on 3D nonlinear flutter analysis method of long span bridges, aerodynamic stability analysis of Yichang suspension bridge over the Yangtze River with symmetrical and non symmetrical erection sequence is performed. The variation of structural aerodynamic stability during erection, the influence of various erection sequence and non linearities on structural aerodynamic stability in erection are studied. |
