Description

This paper describes some experimental tests carried out in the context of the evaluation of the bond behavior associated with NSM CFRP reinforcement. These results were used in the numerical simulation of the material nonlinear behavior of RC beams strengthened with NSM strips. For this purpose, an elasto-plastic multi-fixed smeared crack model was developed and implemented in the FEMIX computer code. The obtained numerical results are compared with those recorded in the experimental tests.
