摘要
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。
Two super-tall buildings with elliptical and rectangular cross-section respectively were tested in wind tunnel and aerodynamics on buildings were measured. Along-wind and across-wind equivalent static wind loads( ESWL),windinduced displacement and acceleration response were calculated to apply to structural design on the basis of results from wind tunnel test. Based on calculation methods in Load code for the design of building structures( GB 50009—2012),ESWL of the two buildings were calculated and compared with the results of wind tunnel test. The impact of vibration mode order on ESWL and wind-induced displacement and acceleration response was discussed respectively.
