Simulation for Wind Pressure of Pedestrian Bridge Induced by Main Line Train

Abstract:

Wind pressure of pedestrian bridge induced by main line train has been investigated using numerical simulation. Based on time-filtered Reynolds Averaged Navier-Stokes equations, meanwhile, the RNG k-ε turbulent model is selected to close the equations, the three-dimensional incompressible unsteady flow computational fluid dynamics model have been established by commercial software FLUENT. The distribution of wind pressure and the time histories of wind pressure on surface of the bottom of bridge are obtained, moreover, the characteristics of variation process are summarized.
