摘要
通过对广东省大学生运动会游泳馆网壳的风洞试验 ,分析研究了网壳结构的风压分布特性 ,并对看台曲面屋盖和游泳池波浪形盖板两种不同结构形式的网壳的风荷载特性进行了比较 ,当气流在弯度较大的屋盖上流动 ,加速较充分 ,屋面呈现较大负压 ,具有较大的升力系数 .不同形式网壳的风压分布的特点为结构工程师进行网壳结构的抗风设计提供了参考和启发 .
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.
