摘　　要：广州良业大厦项目,塔楼2、塔楼3高度约150m,结构平面形状原为矩形,后修改为切角三角形,项目前后进行了两次风洞试验。对风洞风荷载、规范风荷载及结构响应进行了详细比较研究,指出超高层建筑中横风向风振和扭转风振等效风荷载对结构楼层位移角和构件内力的影响显著。同时总结了应用风洞试验数据和确定地面粗糙度类别的的注意事项。Guangzhou Liangye Tower project,two of the buildings are about 150 meters high.The plane shape of the building was originally a rectangle,but later it was changed into a tangential triangle,two wind-tunnel test were conducted.The equivalent wind load of wind-tunneltest,the wind load of Code,and wind-induced structural response are studied in detail.Therefore pointed out that the equivalent wind load of acorss-wind and wind-induced torsional vibration has a significant influence on the interlayer displacement angle and the internal forces of the members of the super-tall buildings.It also summarizes the matters needing attention in the application of wind tunnel test data and the determination of ground roughness category.
