| Abstract: | Based on data obtained from wind tunnel test on the model of the space grid above the natatorium for Guangdong Provincial University Meet,this paper makes a study of the wind pressure distribution characteristics of the structures of the two different space grids above the natatorium,with a comparison between the wind load characteristics of the curved roof above the grandstand and those of the wavy roof above the swimming pool.It has been found that the air flow sweeping over a roof with larger curvature will manifest higher negative pressure with larger lift coefficient. |
