Wind Loading: Uncertainties and Honesty Suggest Simplification Alain H. Peyrot, PhD, PE1 1 Emeritus Professor of Civil Engineering, Univ. of Wisconsin, Madison, WI, USA Past President (1992 to 2008), Power Line Systems, Madison,WI, USA ABSTRACT This paper discusses some of the recent wind loading procedures for the design of Transmission lines (NESC, ASCE, IEC, CENELEC, etc.). It provides some detailed background behind their formulas for gust factors, span factors and gust response factors. It discusses the uncertainties inherent in each one of the parameters and assumptions behind the formulas: wind storm type, reference wind, terrain roughness, profiles, gustiness, time and spatial correlations, dynamic response, wind direction, drag coefficients, etc.
2.1 Extra Tropical Cyclones/ Winter Storms These storms are characterized by circulating winds around very low pressure zones: they are also referred to as cyclonic systems with very large diameters, say between
