Abstract
A two-step computational method performing computational fluid dynamics analysis and structural analysis step by step to solve the coupled wind-structure interaction problem is applied to predict the dynamic response of the long-span bridge structures due to vortex-induced unsteady wind load. For a practical application of the two-step computational method, a simulation method of unsteady wind loads is investigated Three-dimensional dynamic analysis of the bridge structure using the unsteady wind loads calculated through computational fluid dynamics analysis and the simulated unsteady wind loads are followed to compare the structural responses. Reasonable agreement is observed in oscillation amplitudes between the two cases
