When an offshore streamlined box girder is close to the water surface, the aerodynamic performance is easily interfered by extreme wave boundary conditions. To investigate the aerodynamic performance of the streamlined box girder under interferences from extreme wave boundary, the extreme wave is simulated using solitary wave. Based on FLUENT software, a numerical model for the aerodynamic performance of the streamlined box girder under interferences from moving solitary wave boundary is established by layering mesh method. The model is validated and then used to study the interferences from the moving solitary wave boundary on the aerodynamic performance, including aerostatic force coefficients, vorticity magnitude field, and distributions of the mean and fluctuating pressure coefficients of the streamlined box girder, under different parameters of wave boundary moving speed, wind attack angle and bridge clearance. The analysis results show that the aerodynamic performance of the streamlined box girder under the interferences from different solitary wave boundary moving speeds is apparently different from that of no-wave case. With wave boundary moving forward, the direction of the shear layer at the windward corner changes significantly compared to that at the corner of bottom surface (8° wind attack angle) and the top corner of upper leeward surface (−8° wind attack angle). Under the interferences from the moving solitary wave boundary, the buffeting response of the girder will be strengthened with the increment of the magnitudes of wind attack angles.
