The induced static and dynamic response of a two-span continuous composite steel curved box-girder bridge, located in Seoul, Korea, has been examined. The deformations and strains were induced by a calibrated test vehicle. The experimental results, deflections and strains have been compared to results from three analytical techniques. The comparisons show excellent agreement between tests and theory. Because of the high torsional rigidity of the bridge, basic beam theory is adequate in prediciting the response.
