【摘要】 为探索圆角弧边三角形高层建筑的风致干扰效应，文中以圆角弧边三角形双塔高层建筑为对象，采用风洞试验方法，研究了双塔弧面迎风时受扰建筑脉动风荷载的干扰效应。结果表明双塔弧面对称迎风时受扰建筑层脉动阻力系数、脉动升力系数达到最大；当双塔相对间距比不超过2时，弧面不对称迎风时干扰效应会使受扰建筑基底脉动弯矩频谱在高频处出现显著共振能量。更多还原

【Abstract】 This paper adopts the wind tunnel testing method and studies the interference effects of fluctuating wind loads of rounded-corner triangular high-rise twin towers in wind directions where curved-surfaces are windward to explore the wind-induced interference effects of rounded-corner arc-edge triangular high-rise buildings. The results show that the fluctuating drag coefficient and fluctuating lift coefficient of the interfered building reach the maximum when curved surfaces of twin towers are symmetrically windward. When the relative spacing ratio of twin towers is no more than 2 and curved surfaces are asymmetrically windward, the interference effect causes significant resonance energy in the high frequency of the spectrum of fluctuating base moment of the interfered building.更多还原
