Abstract: Wind load amund long span roof is studied by means of CFD. The numerical simulation of wind induced pressure has been performed on flat roof and curved roof such as cylinder dome and saddle roof. On the basis of the research mentionedo, the numerical simulation of wind load has performed on the gymnasium mof of Daqing petmleum institute compared with wind tunnel tests. The numerical simulation of flow around Five-hundred-meter-Aperture Spherical Telescope (FAST) has been performed which can be referred in wind resistant design of the structure.
Keywords: numerical simulation; long span roof; wind load; CFD
