Simulation Research on an Airport Terminal Building from the Perspective of Roof Safety under Strong Wind

Roof insulation damage in large scale terminal buildings under strong wind happens frequently, which is not only related to the circumstance where the building located but also related to the configuration of building itself which influence the micro wind climate and the way building roof response the wind pressure. 3D models of typical layout of terminal complexes were extracted out based on key elements such as efficiency of flows organization at first; Then the models were simulated in a computational fluid dynamics (CFD) plate-form and the simulation results about distribution of wind pressure over roof surface were analyzed in order to find out the influence of building forms. The roof damage accident of Beijing T3 terminal is taken as a case in the research process. The paper ended with suggestion that the wind effluence should be considered seriously and comprehensively in form design of large-scale terminal complex.
