摘　　要：深圳大运中心体育馆屋面为单层折面网格结构,平面呈圆形,但体型不规则,风场特性较复杂,有必要进行风洞试验。通过对风洞试验结果的分析研究,介绍了该大跨结构的群体建筑相互干扰增大系数、屋面不同网格处的风荷载体型系数和风振系数的分析结果。结果表明,体型系数可利用规范给出的相似体型系数通过修正得到较理想的结果,为相似结构在初步分析风荷载作用时提供参考。The roof of Shenzhen Dayun Center Gymnasium is the single-layer space fold surface grid structure with the round plane.Wind tunnel test should be done because of the irregular shape and the complex of wind field characteristics.Based on the analysis of wind tunnel tests,the mutual interference enhancement coefficient of building complex of large span structure,the approximate value of shape coefficient and wind vibration coefficient were introduced.The analysis results show that shape coefficient can be given by similar shape coefficients in load code.Some useful reference was provided for the preliminary analysis of wind load on similar structures.
