wind pressure
3.Some characteristics of the measured wind pressure field were discussed, including distributions of wind pressure, the effects of shape ratio on total wind force coefficients, auto-and cross-power spectral density (PSD) distributions of fluctuating wind pressure, characteristics of the proper orthogonal decomposition (POD) results of the measured wind pressure field, effects of Reynolds number on wind pressure distributions, etc.
8.The behavior of wind pressure distribution on the atrium with long-span roof of Shanghai North Bund Hotel under different wind directions angle was investigated through a(1∶200) model wind tunnel test. The variation situations of wind pressure on atrium structure were measured and studied under different directions wind load.
10.The spectral analysis method for a long-span flat roof structure subjected to wind excitation is established by finite element method. And the wind-induced dynamic response and wind load factor of the long-span flat roofs are evaluated using Davenport wind spectrum and the local mean wind pressure coefficients determined in wind tunnel.
