摘要：	Due to the benefits of having a larger span length, a more elegant structural shape, better adaptability and financial feasibility, the use of self-anchored suspension bridges as solutions in the engineering industry has been widely adopted.Based on the theory of 3D flutter analysis, this study chose to analyze an entire bridge.The effect of initial wind attack angle and static wind loading on the flutter stability of self-anchored suspension bridge was investigated.The results show that the critical flutter wind speed varied noticeably with different initial wind attack angles, and that an angle of +3° gave the most adverse state.Moreover,when static wind loading was considered, while changes in structural vibration characteristics showed little influence on the flutter stability of self-anchored suspension bridge, the added attack angle on the main girder affected the flutter stability remarkably.
