The application of FRP materials at the extrados or intrados of masonry arches sharply modifies the bearing capacity and the failure mode of the structures.

Abstract
The application of FRP materials at the extrados or intrados of masonry arches sharply modifies the bearing capacity and the failure mode of the structures. In this case the classical limit analysis theory, suitable for the collapse behavior of un-reinforced masonry structure, cannot be applied due to the FRP presence, which prevents the formation of a mechanism. The evaluation of the ultimate behavior of reinforced arches with a suitable analytical model has been already proposed by the authors. Aim of the paper is a validation of this model by means of a numerical procedure developed with a FEM program, able to account for the presence of the composite material bonded at the surface. In particular in this paper the analyses will be devoted to the collapse response of masonry arches reinforced with FRP at the intrados and subjected to vertical loads. On the basis of the comparison with numerical outcomes the effectiveness of the analytical methodology in predicting the ultimate load and the failure mode is pointed out.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
