| 摘 要： | 为了给结构(含围护结构)设计提供设计依据,介绍了超大跨度屋盖结构———深圳机场T3航站楼的模型风洞试验和数值模拟的主要结果。给出了屋面在典型工况下的分块体型系数(对应法向风压)和切向风荷载体型系数等值线,清楚地显示了屋面的风压分布特征,结果表明切向风荷载相对法向风荷载较小。同时考虑到作用在围护结构上脉动风压的相关性对极值风压的折减,分析了围护结构设计风荷载的折减因子。

| Abstract: | Testing conditions and main results of wind tunnel test and numerical simulation on Terminal 3 in Shenzhen International Airport were introduced.The block shape coefficients for wind forces acting normal to the building surface and the contours of shape coefficients for wind forces acting tangent to the building surface(friction forces) were given for the typical condition,which showed clearly the characteristics of the wind pressure distribution on the large-span roof surface.It is found that the wind forc... |
