Nonlinear Analysis of R.C Beams Strengthened with CFRP
In order to study on the flexural performances of beams strengthened with external bonded carbon fiber reinforced polymer(CFRP)sheets, nonlinear analysis is carried out by using software ANSYS. The results show that a reasonable finite element model, using a reasonable solution strategy can be a good simulation of CFRP flexural performance of reinforced concrete beams, and finite element analysis results with the experimental results have good consistency .The beams reinforced by carbon fiber polymer,the capacity of flexural resistance increased with the numbers of carbon fiber paste sheets, reinforced components of flexural capacity significantly improved, but the extent of its increase is not proportional with the numbers of carbon fiber paste sheets.
