Abstract: This paper analyzes the fatigue collapse of two slender structures due to wind-induced vibrations. The analysis is based on a complete procedure for the wind-induced fatigue analysis proposed by the authors. The application of the proposed method, compared with the real cases examined, leads to accurate fatigue life prediction; moreover, it gives a complete picture of the stress state and damage of the structures, furnishing useful information on the structural behavior and a key for the interpretation of collapses and damage causes. In particular, the analysis highlights the critical aspects of the aerodynamic behavior of the considered structures and suggests some remarks on the current state-of-the art on design against wind-induced actions.
