Abstract Based on wind tunnel tests, time-varying wind pressure distribution on the finite element model of a super-large hyperbolic cooling tower under group-tower environment were reconstructed by the radial basis function (RBF) method. The results were applied in time-domain calculations of wind-induced responses of the cooling tower. Then, the gust loading factor (GLF) method adopted in current engineering practice was analyzed. The results indicate that: due to some inevitable limitations, the existing GLF scheme, in which a unified amplification factor G is adopted to calculate the equivalent static wind loads, may not be applicable for super-large cooling towers.

超大型冷却塔风振响应及GLF分析

摘要 基于风洞试验，采用径向基函数（RBF）方法重建了群塔环境下超大型双曲线冷却塔有限元模型的时变风压分布。将结果应用于冷却塔风致响应的时域计算。然后，分析了当前工程实践中采用的阵风载荷因子（GLF）方法。结果表明：由于一些不可避免的局限性，采用统一放大系数G计算等效静风载荷的现有GLF方案可能不适用于超大型冷却塔。
