Titre : Closed-form prediction of the alongwind-induced fatigue of structures Type de document : texte imprimé Auteurs : Maria Pia Repetto, Auteur ; Giovanni Solari, Auteur Année de publication : 2012 Article en page(s) : pp.1149–1160. Note générale : Génie civil Langues : Anglais (eng) Mots-clés : Design codes Environmental effects Fatigue damage Stochastic analysis Variable amplitude fatigue Résumé : Wind-induced fatigue is a crucial topic in the design of wind-sensitive structures. Despite this, methods proposed in literature are mainly addressed to research, or they are too simplified for engineering applications. Thus, suitable engineering and standards procedures are almost totally lacking, which is a major shortcoming in structural and wind engineering. Starting from a closed-form solution (CFS) recently proposed by the authors, this paper develops a novel engineering approach to evaluate the alongwind-induced fatigue of structures and structural elements. This approach is based on a hierarchy of hypotheses that lead to a progressive simplification of the basic formulation. Two classes of formulas, referred to as Levels I and II CFSs, are obtained and critically discussed with special concern for input parameters. Level I CFS implies three further simplifications joined together by the common aim of providing refined approximations of the reference target solution. Level II CFS implies three different simplifications joined together by the common aim of providing easy solutions on the safe side. This set of CFSs is framed within a general procedure that any country, society, or engineer can easily personalize to a situation and requirement, ranging from numerical tools to manual engineering calculations and code provisions.

Titre : Double Proper Orthogonal Decomposition for Representing and Simulating Turbulence Fields Titre original : Double Décomposition Orthogonale Appropriée pour Représenter et Simuler des Champs de Turbulence Type de document : texte imprimé Auteurs : Tubino, Federica, Auteur ; Giovanni Solari, Auteur ; Schueller, Gerhart L., Éditeur scientifique Année de publication : 2006 Article en page(s) : 1302-1312 p. Note générale : Génie Mécanique Langues : Anglais (eng) Mots-clés : Turbulence Wind forces Models Simulation Forces de vent Modèles Index. décimale : 621.34 Résumé : The Modeling and simulation of the wind field along structures is a fundamental step in the analysis of their wind excited response. The Proper orthogonal decomposition (POD) provides efficients tools to formulate a model of the turbulence field based on principal components. This Paper proposes a representation of turbulence based on a double application of the proper orthogal decomposition. Considering a linear domain and generalizing an analogous previous solution concerning the classical components. Closed form expressions for the eigen values and eigen functions of the principal turbulence field are obtained. Based on this representation, a very efficient simulation scheme for the three correlated turbulence components along a linear domain is introduced.
La Simulation modelée du gisement de vent le long des structures est une étape fondamentale dans l'analyse de leur réponse passionnante par vent. La décomposition orthogonale appropriée (COSSE) fournit des outils d'efficients pour formuler un modèle du champ de turbulence basé sur les composants principaux. Cet article propose une représentation de turbulence basée sur une double application de la décomposition orthogal appropriée. Vu un domaine linéaire et généraliser une solution précédente analogue au sujet des composants classiques. Des expressions fermées de forme pour les valeurs d'eigen et les fonctions d'eigen du champ principal de turbulence sont obtenues. Basé sur cette représentation, un arrangement très efficace de simulation pour les trois composants corrélés de turbulence le long d'un domaine linéaire est présenté.
