Original studies on gust factor, maximum response and equivalent static forces deal with alongwind displacements.

Abstract

Original studies on gust factor, maximum response and equivalent static forces deal with alongwind displacements. Researches on these topics carried out in the 90's follow two distinct lines: the first is aimed at determining the maximum effects due to the alongwind response; the second extends the original methods to crosswind and torsional vibrations. The authors have recently joined these two research lines by deriving the maximum effects associated to the 3-D wind-excited response of slender vertical structures and showing that a suitable definition of a 3-D gust effect factor provides, through one closed formula, any effect at any level. This paper applies this criterion to discuss the role of the aerodynamic admittance on structural effects and their implications in structural design.
