Abstract

Abstract This paper presents a nonlinear finite element model for the flexure-shear response of reinforced concrete (RC) beams strengthened externally by epoxy bonded steel plates. The model includes a special interface element to simulate the thin epoxy adhesive layer and which allows for the metamorphosis of failure mode from plate yielding to separation as the plate thickness t p is increased. The numerical results show close correlation to experimental data available for an RC beam strengthened by plates of various thickness.
