ABSTRACT
Due to damage during earthquakes, construction or design problems, reinforced concrete beams usually need to be retrofitted in order to resist shear stresses. For this retrofit, an increasingly attractive alternative is the use of carbon fiber reinforced polymers (CFRP). A computational model based on 3D non-linear finite elements was developed to simulate the behavior of reinforced concrete beams retrofitted with anchored CFRP strips. The model results were compared with experimental tests, showing good correlation in the parameters studied and proving the computational model to be a useful tool to study mechanisms hardly observed with experimental tests.
