Wind Pressure Distribution Rules for Complicated Roof Structures with Holed Surface

摘要：

To estimate the wind load distribution on the large span flexible roof structure is a key problem for designing and monitoring.The distribution of average wind pressure on the upward and downward surface of roof structure of Shenzhen Citizen Centre is studied in this paper in body conformation changing from plane to the real roof shape.When the body conformation approach the real shape,the wind pressure coefficients of almost all the monitoring points are changed in a similar rule except for the different values.The average internal and external pressures under different wind attack angles and wind directions are also studied with different holed area ratio.Some conclusions are obtained that the total pressure of the solid surface side under arbitrary attack angles is unfavorable to the roof structural safety; however,the total pressure of holed side surface under almost all attack angles is favorable to the structure safety.
