Study on Bond Behaviour of Corroded Reinfoced Concrete Beam – Finite Element Analysis

Abstract

Present work contains a 3-D Finite Element model created in Abaqus to examine bond behavior in controlled/non-corroded Reinforced Concrete beams. Study evaluated the compatibility between corrosion levels and beam deflections. Cohesive surface-based interaction method is applied to the Data obtained from recent studies in which corrosion was induced by accelerated corrosion technique. The cohesive surface-based interaction approach has been found to be suitable for simulating the interfacial binding between reinforcement bars and the concrete. Analysis of Control and corroded beams along with mesh sensitivity are used for the validation of the work. Study demonstrated that experimental and analytical research are in good agreement with considered level of corrosion and corresponding deflections. The modelling outcomes can be used to validate the bond behaviour of Reinforced concrete cantilever beams without considering the influence of stirrups.
