Abstract
This study investigates a turbulent wind-induced dynamic behavior of a soundproof tunnel structure with un-symmetric shape. The combined computational fluid dynamics (CFD) and fluid-structure interaction (FSI) simulations proposed in this study may allow us not only to investigate realistic wind effects but also to provide various parameters for the structural design. The CFD and FSI simulation were verified in comparisons with a full-scale experiment of soundproof frames. Subsequent simulation results present that displacements, stresses, and shear forces induced from the FSI analysis are heavily dependent on curved shapes and the wind direction of the soundproof tunnel. From parametric results, the technique proposed in this study is computationally efficient in characterizing behaviors for complex structures such as soundproof tunnels with un-symmetric shapes.
