| Abstract: | Located in Changsha City across Xiangjiang River, Sanchaji Bridge is a self-anchored suspension bridge with 5 continuous spans and main span of 328m. Being designed as a special structure with a few new features, it is necessary to study its flutter characteristics against natural wind. A detail wind-resistant study is carried out in Research Center of Wind Engineering, Hunan University. In this paper, basic design information is first described, followed by briefly introduction to section model and full aeroelastic model wind tunnel tests. Researches clearly demonstrated that this suspension bridge is of better flutter stability in completed stage. |
