Modélisation de structures corrodées par une approche multifibre

ABSTRACT This paper deals with the rust influence on the structural behaviour of reinforced concrete structures. A constitutive model accounting for area reduction and mechanical brittleness increase is presented. This model has been implemented within a multifibre beam type finite element. The relevance of such an approach to describe the macroscopic behaviour of corroded reinforced concrete structures subject to external mechanical load is emphasised.
