Wind tunnel tests and analyses of the response of the Seo Hae Grand Bridge were conducted using section model technique. A 1/80 scale section model were used to develop the optimum section to minimize vortex shedding induced vibration without reducing the flutter speed. The final configuration was comprised of a combination of the replacement of the $quot;New Jersey Barrier$quot; with a railing type traffic barrier and $quot;Flow Reattachment Vanes$quot; at the upper and lower edge surfaces of the deck and main girder. 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.
