Contribution à la modélisation des stuctures en béton armé par la méthode des éléments finis

A computer program is developed for the finite element nonlinear analysis of two-dimensional reinforced concrete structures under monotonie loading. The smeared-crack approach is used and the reinforcement is considered uniformly distributed within the element. An elastic work-hardening plastic stress-strain relationship with nonassociated flow rule is assumed for the concrete in compression an...

Modélisation des massifs rocheux fissurés par la méthode des éléments distincts

The subject of this thesis forms part of a research program dealing with fractured rock masses being undertaken by the "Centre de Géologie de l'Ingénieur (CGI)" from the "Ecole Nationale Supérieure des Mines de Paris (ENSMP)" and the "Ecole Nationale des Ponts et Chaussées (ENPC)". In fractured rock masses, it is very difficult to undertake engineering works without analysing, beforehand, the f...

Propositions pour la pondération des termes et l'évaluation de la pertinence des éléments en recherche d'information structurée

Structured Information Retrieval copes with a number of open issues. One can cite the evaluation of elements relevance: the aim is to return to the user a ranked list of results. This evaluation is based on the term weighting scheme and on the model used for the matching of queries and elements. In this paper, we propose to explore some clues to answer to this problem. For example, we propose t...
