Three-Dimensional Numerical Modeling of a Coastal Highway Bridge under Stokes Waves

This article investigated the effect of structural flexibility on a coastal highway bridge subjected to Stokes waves through a three-dimensional numerical model. Wave-bridge interaction modeling was performed by an FSI model with the coupling of finite element and finite volume methods. An experimen...
