Non-Linear Finite Element Analysis of FRP Strengthened RC Beams Using ANSYS

Abstract

Most of the reinforced concrete (RC) structures get   damaged   during   earthquakes and   they need replacements. Presently several studies have been conducted to investigate the flexural strengths of reinforced concrete members with fiber reinforced composites. This paper presents the finite element analysis of control RC beam and strengthened beams with carbon fiber reinforced polymer (CFRP) composite sheets carried out using ANSYS software. In this study, a control beam was modelled, the results were analyzed, and then strengthened beams were modelled and analyzed. The results of the control and strengthened beams were compared with the experimental results. It was observed that the results of the strengthened beams are in close agreement with the experimental results.
