Optimal FRP strengthening of masonry arches

When conservation of historical constructions goes beyond simple modifications or minor superficial reparations, an understanding of the structural behaviour is required. In order to assure a better performance of old buildings during its life expectancy, an original representative structural model needs to be found first, and then a different strengthened structure has to be analyzed. Semicircular unstrengthened and strengthened masonry arches were numerically modelled to evaluate the effectiveness of different FRP strengthening proposals. The paper presents results and conclusions regarding the optimal strengthening of masonry arches.Fundação para a Ciência e a Tecnologia (FCT) - POCTI-ECM-38071-2001 (“Strengthening of masonry arches with composite materials”).
