An experimental and numerical analysis of the structural behaviour of a barrel
tuff masonry vault strengthened by a Fiber Reinforced Cementitious Matrix (FRCM)
reinforcement system it is proposed. The geometry and the materials of the vault are
representative of some historical constructions in Apulia (Italy). The vault, under the action
of the self-weight and of a distributed load representative of the infill, has been first damaged
by differential settlement of abutments, and then repaired and strengthened by FRCM
composites. Finally the structure has been subjected to a increasing concentrated load on the
extrados. A 3D heterogeneous FE Abaqus numerical model describing the above mentioned
experimental conditions is carried out in order to reproduce the response of the FRCM
reinforced vault. The obtained experimental and numerical results allows for discussing the
structural behaviour of the reinforced vault, and then the effectiveness of the employed
reinforcement
