| Abstract: | Based on an actual structural project,a wind tunnel test of 26 inverted umbrella-shape structures was carried out in TJ-3 boundary layer wind tunnel in Tongji University.The wind loads on the structures(canopies)were analyzed in detail according to the test results,such as the mean and root-mean-square(rms)pressure coefficients,area shape coefficients and overturning moment coefficients in some typical wind directions.The wind pressure distribution characteristic on the upper and lower surfaces and the net ... |
