Numerical Simulation of Wind Loading Shape Coefficient  on a New Airport Terminal

Abstract

Abstract: Based on the project of new Kunming Airport Terminal, the wind field and wind pressure distribution of structural surface was simulated by commercial computational software with standard kε turbulent model, while parameter analysis such as coming wind angle was carried out. The investigation indicates that the numerical results of wind pressure distribution on the roof are somewhat greater than the wind tunnel experiment results and the wind loading shape coefficients vary greatly with the coming wind angles. It should be mentioned that the most unfavorable wind pressure distribution should be obtained according to local wind environment, in order to provide a reference for windresistant design of practical eningeering project.

Key words: large span roof structure, kε , turbulent model, wind loading shape coefficient, numerical simulation, wind tunnel test
