Aerodynamic study on a proposed cable-stayed bridge in Shanghai, China
AbstractThis paper deals with the aerodynamic study on a proposed composite deck cable-stayed bridge alternative over the Huangpu River in Shanghai, China. The non-steady aerodynamic model is identified directly by taking the coupled vibration response (CVR method) records under initial impulse as basic information obtained from section model wind tunnel test. The 3-D flutter analysis in full-process (from construction stage to completion stage) is carried out by using the state-space method. The analysis indicates that the alternative proposed has enough wind-resistant aerodynamic stability at completion stage, but it is necessary to add some ties or guys to raise the wind-resistant capability at the construction stage. The result of 3-D flutter analysis is also verified by the full-bridge model wind tunnel test, a first attempt of such test in China.
