Effect of Crosswind Angle on the Surface Pressure Distribution of Intercity Trains on Viaducts Under Wind-Driven Rain Environment
The turbulence effect of the pulsating wind is worsened by the strong wind-driven rain environment, which intensifies its impact on the structure, making the aerodynamic safety problem of trains on viaducts un...
