凹凸变化截面超高层建筑围护结构风荷载研究

Research on wind loading of enclosure structure of super-high-rise building with concave-convex cross section

基于一凹凸变化截面的刚性模型表面压力测量风洞试验结果,对超高层双塔建筑立面上测点的最不利风压系数进行了研究,分析了复杂截面及邻近的姊妹塔楼对建筑立面上围护结构风荷载的影响,得到了一些有用的结论。

Based on the wind tunnel test result for the superficial pressure measurement of some stiff model with the concave-convex cross section,the paper researches the most unfavorable wind pressure coefficient of the tested points of the elevation at the super-high-rise double-tower buildings,analyzes the influence of the complicated cross sections and neighboring sister towers on the wind loading of the enclosure structure of the elevation of the buildings,and achieves some beneficial conclusion.
