适用范围

ESDU 89049 provides a step-by-step calculation method for estimating the loading and response@ in both translational and torsional modes@ due to the across-wind turbulence components. The loading is derived as the sum of a mean contribution together with background and resonant fluctuating contributions. The method uses precalculated loading factors and they are provided in both graphical and equation forms@ based on the atmosphere model of the Series@ for the estimation of the fluctuating contributions. Worked examples illustrate the use of the method@ which applies to vertical or horizontal structures (or structures normal to the wind but inclined across-wind)@ cantilevered or pinned at both ends or supported remote from a ground plane. See ESDU 01008 for a program of the method presented here.
