Aeroelastic Full Model Testing of the Santou Bay Bridge in Guangdong Province

The Santoll Bay bridge is the first long-span suspension bridge in China with a pre-stressed concreat6 deck, a center span of 452m and a side span of 154m. This bridge is located near Santou seaport, where typhoon comes often. In order to investigate the wind-resistance behavior of the bridge, an aeroelastic full bridge model test and buffeting analysis are carried out.In designing the model,(E/G) is introduced as a new variable to meet the determination of the sizes of the deck core cross section, which has a rectangular shape to satisfy the simulation of the vertical bending, lateral bending and torsional stiffness, E and G are, here, elasticity and shear elasticity of the core material respectively. The method can be spread to a greater extent. The model simulates the operation stage and two construction stages.The flutter critical wind speeds and buffeting responses from the t6st are found to agree well with the sectional model test and the calculation results.
