THESE SOUTENUE DEVANT L’INSTITUT NATIONAL DES SCIENCES APPLIQUEES DE LYON

NOM : ROBERTDATE de SOUTENANCE

Prénom : Florent Jean-Claude Germain2 avril 1999

TITRE :

Contribution à l’analyse non linéaire géométrique et matérielle des ossatures spatiales en Génie civil.

Application aux ouvrages d’art.

NATURE : Doctorat Numéro d'ordre : 99ISAL0032

Formation doctorale : Génie civil : Sols, matériaux, structures, physique du bâtiment

Ecole doctorale : MECANIQUE, ENERGETIQUE, GENIE CIVIL, ACOUSTIQUE (MEGA)

Cote B.I.U. - Lyon : T 50/210/19 / et bis CLASSE :

RESUME : En Génie civil, la tendance actuelle à concevoir des structures de plus en plus élancées et le besoind’optimiser les quantités de matériau, conduisent les projeteurs à mener des calculs prenant en compte les non-linéarités du système. En

ouvrage d’art, considérer le couplage entre les non-linéarités matérielle et géométrique est impératif, d’où la nécessité de disposer d’outils

informatiques adaptés au métier et résolvant ce problème. Nous proposons une formulation basée sur les coordonnées convectées spatiales en

décomposant le mouvement d’une particule en un mouvement de corps rigide de grande amplitude et un mouvement modéré induisant les

déformations. Ceci permet de prendre en compte les grands déplacements et les grandes rotations pour des éléments de poutre

tridimensionnels alors que la non-linéarité matérielle repose sur l’hypothèse des petites déformations. On peut ainsi modéliser les ossatures

spatiales composées de métal, de béton armé ou de béton précontraint. Les effets différés, à savoir le retrait et le fluage du béton ainsi que la

relaxation des aciers de précontrainte, sont intégrés dans le schéma général de résolution. Pour simuler la construction des ouvrages d’art et

étudier leur schéma statique, nous développons la prise en compte des grands déplacements pour les articulations ainsi qu’un élément

simulant correctement le comportement d’un cible pesant, même lors des phases où il est détendu. Nous développons le calcul d’instabilité

élastique à partir de la matrice des contraintes initiales issue de notre formulation. Nous proposons l’extension possible de l’algorithme de

résolution du cas de chargement statique au cas dynamique. Nous validons notre approche en confrontant les résultats de nos calculs à des

mesures expérimentales ou à la solution théorique de cas tests représentatifs. Enfin, un exemple d’utilisation du programme sur un projet réel

est présenté : la simulation du remplacement du système de suspension du Pont de Tancarvillc..

MOTS-CLES : Constructions à ossatures, éléments finis, poutre, béton armé, béton précontraint, non-linéarité,

ouvrages d’art, grands déplacements.
