Abstract :
[en] The main objective of this study is to numerically investigate rehabilitation of corrosion-damaged reinforced concrete (RC) beams with carbon fiber reinforced polymer (CFRP). In this study, three dimensional (3D) finite element (FE) models for the RC beams, strengthened with FRP sheets, was created. The effect of repairing on corrosion damaged RC beams has been investigated using FRP on load carrying capacity, ultimate deflection and ductility. To achieve these objectives, a beam with average steel mass losses of 31.6% was strengthened with various procedures using CFRP sheet. In addition, a beam with average steel mass losses of approximately 14.2% was strengthened. Results indicate that strengthening of all procedures using FRP sheet increase load carrying capacity and reduce ultimate deflection of the beam. In addition, the effect of strengthening on ultimate load carrying capacity of the beam keeps on increasing with the increase in percentage of corrosion.
