武汉国际证券大厦三维风荷载的风向效应
Effect of the Three Dimensional Wind Loads Considering the Direction on Wuhan International Stock Building
【摘要】 通过风洞试验,对武汉国际证券大厦模型180~°270°风向角范围内的三维风荷载谱进行了分析,得到三维风荷载谱随风向角的变化规律及其产生机理,进而做出了若干结论.此外,分析了该大厦最高居住楼层的最大加速度响应随风向角的变化,得到了风向对最大加速度响应的影响规律.
【Abstract】 The spectra of three dimensional wind loads on the model of Wuhan International Stock Building is investigated in a boundary layer wind tunnel when the wind direction varies from 180° to 270°.Based on the experiment investigation,the law varying with wind directions of three dimensional wind load spectrum and its mechanism are analyzed,and some conclusions are obtained.Wind induced maximal accelerations at the highest inhabitancy floor are analyzed as wind direction varies and the effects of wind direction to acceleration response of the building are obtained.
