Constitutive Laws of Corroded RC Elements Repaired by FRP Sheet %K Reinforced concrete %K Corrosion %K FRP %K Constitutive Laws %R 10.22060/ceej.2014.307 %X Corrosion of reinforcement has very serious effects on structural behavior of reinforced concrete structures. Because of damages due to corrosion, several methods of reviving of such structures have been developed. Using of FRP sheets is one of them. In this research, the compression and tension behavior of corroded RC elements strengthened with FRP sheet is surveyed through modeling of these elements by the means of COM3 and WCOMD software developed at the University of Tokyo and a written program in FORTRAN code. Fixed smeared crack approach has been used for nonlinear analysis. In this method, the average behavior of materials (including concrete, reinforcing bar and FRP sheets) is applied in the modeling. After attaining the material constitutive laws of corroded RC elements and also repaired ones by FRP sheet, the consequences are verified through a comparison with laboratory test results. %U https://ceej.aut.ac.ir/article_307_fdca8eaeef09cc2f255e0055f631a9be.pdf
