“…CFD has been applied successfully to the calculation of aerodynamic loads on trains and bridges (He et al, 2016; Wang et al, 2013; Yang et al, 2015). In this study, the aerodynamic models for the bridge and train were constructed using the CFD software FLUENT 16.0 (ANSYS, Inc., 2015a).…”

When a train crosses a bridge in a crosswind environment, the coupled vibration problem of the train-bridge system becomes prominent, and train safety and riding comfort are difficult to guarantee. Therefore, using the Pingtan Strait bridge in China as a case study, a co-simulation platform for the train-bridge system coupled vibration in crosswind environments was established based on computational fluid dynamics, finite element method, and the multi-body system dynamics. Based on this platform, dynamic response analysis of the train-bridge system was performed at different wind and train speeds. The results indicate that the dynamic response of the train and bridge under double-line conditions is greater than that under single-line conditions. With an increase in wind speed, the mid-span vertical displacement of the bridge changes little, while the lateral displacement increases significantly. Meanwhile, with increasing wind and train speeds, the train dynamic indexes obviously increase. Moreover, the dynamic index of the head car is the largest among all the train sections.

To ensure the safety of bridges, the comfort of pedestrians and vehicles on bridges, the vortexinduced forces on flat-steel-box girders need to be investigated. The total vortex-induced forces integrated on the surfaces of girders have been studied extensively. This study will be mainly focused on the characteristics of surface distributed vortex-induced force, which can be beneficial to the vortex-induced vibration (VIV) reduction with local aerodynamic optimization. Computational Fluid Dynamics (CFD) method is employed for the simulation of the VIVof a flat-steel-box girder. The simulation results are verified through the comparison with the results of corresponding wind tunnel test. A self-adaptive nonlinear fitting method is proposed to determine the vortex-induced force model. A vortex-induced force contribution factor is defined to account the contribution of the components and the surface location. Based on the surface distributed vortex-induced force analysis, several conclusions are made. The vortex-induced force presents a fairly strong multiple-frequency characteristic, and the high-order terms should be carefully considered. Most energy of the VIV comes from the linear and third-order aerodynamic damping terms. In terms of location, the roof takes most of the aerodynamic damping and the total vortex-induced force. The flow separation around the underside upstream corner, the underside downstream corner and the middle downstream comer lead to large third-order aerodynamic damping term. The flow separation around the underside upstream corner has great contribution to the linear aerodynamic stiffness term.

The performance of bridges under strong wind and traffic is of great importance to set the traveling speed limit or to make operational decisions for severe weather, such as controlling traffic or even closing the bridge. Meanwhile, the vehicle"s safety is highly concerned when it is running on bridges or highways under strong wind. During the past two decades, researchers have made significant contributions to the simulation of the wind-vehicle-bridge system and their interactive effects. This paper aims to provide a comprehensive review of the overall performance of the bridge and traffic system under strong wind, including bridge structures and vehicles, and the associated mitigation efforts.
