Nonlinear FE Analysis of Reinforced H.S. Concrete Continuous Beam Strengthened with CFRP Sheet

Majid Mohammed Ali Kadhim

Abstract

This paper is focused on the nonlinear finite element analysis of the reinforced high strength concrete continuous beam strength with carbon fiber reinforced polymer sheet. Three full scale continuous beams are analyzed under two points load; the data of analysis are compared with the experimental data provided by Akbarzadeh and Maghsoudi [1]. ANSYS V.11 program is used in FE analysis, the results obtained from analysis give good agreement with experimental result when compared load-deflection responses, ultimate strength, and the crack patterns. The results showed that with increasing the number of layers, the ultimate strength of beams are increase by amount reached (14%) for each layer. The failure mode different by increasing number of CFRP sheet layers when the beam strengthened by one layer of CFRP sheet failed by tensile rupture of CFRP sheet, and beam strengthened by more than one layer failed by intermediate crack (IC) debonding of CFRP sheet.
