In the present study, the wind pressure acting on the platform screen door is investigated numerically by a train-induced wind and a typhoon. The dual island platform on a ground-level station was considered as a computational domain. To make a stable simulation, detailed buildings and station structures were modeled in a 2 km long, 1 km wide and 200 m hight computational domain. The high-speed train and station were modeled as detail as possible, and the actual train operation was considered to build similar analysis conditions. The overset mesh method was adopted to consider the high-speed train"s mesh displacement. The three-dimensional, unsteady, compressible flows were simulated to obtain the wind pressure effect on the platform screen door. Simulation results were within the safety standards in all train and typhoon conditions considered in this study, confirming that the platform screen door design was within a safety range. It is also observed that when the typhoon blows diagonally to the platform screen door, the highest pressure load occurs on the platform screen door. Through this study, it is possible to check and confirm the safety requirements of the designed platform screen doors.
