| Abstract: | Wind load on the canopy roof of a railway station was studied numerically.Finite element models were set up for the canopy roof.Time histories of wind velocity and wind pressure on the canopy roof were simulated according to wind power spectra.The dynamic behaviour of the roof structure was then obtained by time history analysis,based on which the gust effect coefficient was determined.Gust effect coefficient was determined to calculate the wind load for the design of the roof structure. |
