对椭圆形截面和矩形截面的两栋超高层建筑进行了风洞试验,获得了作用在结构上的气动力。在此基础上计算得到了用于结构设计的顺风向、横风向的等效静力风荷载及风振位移和加速度响应。基于《建筑结构荷载规范》(GB 50009—2012)给出的方法计算了两栋高层建筑的等效静力风荷载,与风洞试验的结果进行了对比,并进一步讨论了振型的阶数对等效静力风荷载、风振位移和加速度响应的影响。
Wind tunnel tests were conducted on two super high-rise buildings with oval cross section and rectangular cross section, and the aerodynamic forces acting on the structure were obtained. On this basis, equivalent static wind loads and wind-induced vibration displacements and acceleration responses of the windward and transverse winds for structural design were calculated. The equivalent static wind load of two high-rise buildings is calculated based on the method given in “Building Structure Load Specification” (GB 50009-2012), which is compared with the result of wind tunnel test. The order of vibration mode Equivalent static wind load, wind vibration displacement and acceleration response.
