Analysis of bond behaviour in strengthened reinforced concrete beam with carbon fiber reinforced polymer lamella

Abstract

Carbon fiber reinforced polymer (CFRP) can be used to strengthen the reinforced concrete (RC) beams. The debonding is the main failure model and strengthening is limited. The paper deals with the finite element analysis of influence of CFRP strip on stress distribution in a steel reinforced concrete beam loaded by four-point bending on RC beam with and without CFRP lamella. Simulation of the delamination is modelled by a cohesion zone material model using ABAQUS and ANSYS software.
