高层建筑的等效设计风荷载与风振响应研究

Equivalent design wind loads and wind-induced acceleration responses of a tall building

基于某典型高层建筑详细的风洞试验结果,计算分析了该结构的基础等效静风荷载及结构顶部峰值加速度响应,与前期的风洞试验结果相对比,评估了不同风洞试验条件和周边建筑对试验结果的影响,获得的结果可以用于此结构的抗风设计以及居住者舒适度评估。

Wind tunnel test for a typical tall building was conducted in a boundary layer wind tunnel. This paper presents some selected results of the base equivalent static wind loads and wind-induced acceleration responses from the analysis of the data obtained in the wind tunnel test. In addition, the results from a previously conducted wind tunnel test were also used for comparative study, and the effects of boundary layer conditions and surrounding building conditions were investigated. The outcomes of this study were used for the structural design and serviceability evaluation of the tall building.
