Stress analysis of masonry vaults and static efficacy of FRP repairs

In the paper, the basic principles for the analysis of structures made by Not-Resisting-Tension (NRT) material are introduced; the theory is then applied for investigating the static behaviour of a NRT masonry arch model and to test the effect of reinforcements made by FRP strips of variable length. A wide experimental campaign is developed and numerical/ experimental comparison is provided in order to evaluate the skill of the adopted model in capturing the real behaviour of the structure with or without reinforcement
