Abstract:This paper proposes a model of the mechanical behavior of corroded reinforced concrete members subjected to bending under service load. The model is based on the formulation of a macro-element to be used in finite element analysis, having a length equal to the distance between two consecutive flexural cracks and a cross-section equal to the member cross-section. The mechanical formulation is based on the concept of the transfer length necessary for the transmission of tensile load from the reinforcement to tensile concrete through bond. It is thus possible to take into account the effect of reinforcement corrosion on the bond between the steel and concrete by increasing the transfer length as a function of the intensity of corrosion. The variation of the transfer length with degree of corrosion is expressed using a scalar damage parameter. Experimental validation is performed on a 17-year-old beam kept in a chloride environment under its service load.
