This paper presents the experimental behaviour of two reinforced concrete T-beams strengthened in shear with CFRP. The beams are extracted from an important building of the mid-'30s in Rome. The goal of this research is to evaluate the shear strength of the retrofitted beams with the simultaneous occurrence of a negative bending moment. The tests are performed at the Experimental Laboratory of the Structural Department of the University "Roma Tre". In the meantime the two beams are modelled with the software ATENA in order to perform numerical simulations of the tests. The numerical results seem to be in good agreement with the experimental data in terms of load- displacement response, strain state, crack pattern and failure mode.

Abstract
This paper presents the experimental behaviour of two reinforced concrete T-beams strengthened in shear with CFRP. The beams are extracted from an important building of the mid-'30s in Rome. The goal of this research is to evaluate the shear strength of the retrofitted beams with the simultaneous occurrence of a negative bending moment. The tests are performed at the Experimental Laboratory of the Structural Department of the University "Roma Tre". In the meantime the two beams are modelled with the software ATENA in order to perform numerical simulations of the tests. The numerical results seem to be in good agreement with the experimental data in terms of load- displacement response, strain state, crack pattern and failure mode.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
