Wind tunnel tests and analyses of the response of the Seo Hae Grand Bridge were conducted using section model and full aeroelastic model technique. A 1/80 scale section model was used to develop the optimum section to minimize vortex shedding induced vibration without reducing the flutter speed. In order to evaluate the sensitivity of the response to changes in structural damping, a series of tests were conducted with three different values of structural damping ranging from 0.2% to 1.0% of critical. Several options to increase the critical wind speed for torsional flutter were described and solutions proposed. Comparisons of the response from the 1/250 scale full aeroelastic model test were made with those from the section model tests. The results of the Equivalent Static Analysis were also compared with the measurements made on the full aeroelastic model. Aspects of the results for the erection stages are also made.
