摘要 风荷载是高层建筑的控制荷载。抗风设计中必须准确得到风荷载引起的结构整体静、动态力与力矩。为此制作了一轻质刚性缩尺模型,采用高频动态天平技术在大气边界层风洞中进行测力试验,给出高220m的重庆某大夏在不同风向条件下结构总体承受的气动力与力矩系数,从而为大厦主建筑工程的结构抗风设计提供了依据。 Wind loads play the most important role in the wind-resistant design for the building with a height of 220m in Chongqing. The whole static and dynamic forces induced by wind loads must be accurately studied. Therefore, rigid model is made and high-frequency-force-balance technique is used for determining the force in the boundary layer wind tunnel. This paper gives the coefficients of aerodynamic forces under different wind direction condition and offers reference for the wind resistant design of the building.
