摘要
针对目前国外有锥度圆截面高耸结构横风向响应计算的复杂性和国内在此方面研究的不足,根据随机振动理论以及B.J.V ickery提出的横风向力谱,推导了计算有锥度圆截面高耸结构最大横风向响应的简化公式。在应用于工程计算方面,简化方法和基于随机振动理论的标准方法有着很好的一致性,而B.J.V ickery近似方法的预测值偏小。
Now it is complex to calculate across - wind response of tapered high - rise structures with circular section abroad and its research at home is inadequate. Based on random vibration theory and across-wind force spectrum proposed by B. J. Vickery, a simplified formula on maximum across- wind response of tapered high-rise structures with circular section is achieved in this paper. With respect to engineering calculation, the results obtained by simplified method corresponds with those obtained by standard method based on the theory of random vibration well, but the prediction values by approximate method proposed by B. J. Vickery are smaller.
