Abstract
Wind-induced fatigue is a crucial topic in the design of slender structures. Based on a closed-form solution proposed by one of the authors, this paper reports an engineering approach developed to evaluate the buffeting-induced fatigue life of structures and structural elements. Two classes of formulas, referred to as detailed and simplified calculations, are shown. The detailed calculation provides refined approximations of the reference target solution, while the simplified calculation provides easy solutions on the safe side. The novelty of this paper is that it completes the formulation with analytical assessment of input parameters, fully coherent with standards format. Furthermore, the method has been applied to a turbulence-sensitive structural type of sign support structures. Large-scale inspections show that many of these structures suffer for fatigue damages. The comparison between the inspection outcomes and the proposed method results shows a very good agreement, while the European standard assessment provides unreliable results of fatigue life of this kind of structures.
