On the background of grandstand cantilevered roofs of two aiding foreign stadiums, the wind resistance of two large cantilevered roofs with different structure forms is compared on the basis of pressure data acquired from wind tunnel test of rigid models, according to their models, frequencies, mean wind pressure coefficients and fluctuating wind pressure power spectrum densities. A conclusion is made that the arch on the front edge of the large roof can improve the wind resistance, and is validated by calculating wind induced responses of the two kinds of the large roofs. Finally, several reasons for that the arch on the front edge is beneficial to the wind resistance of the large cantilevered roof are concluded.
