Seismic improvement of historical dry masonry building using baslt fibre ropes: the case of Lossetti Tower in Beura Cardezza (Italy)

Dry stone masonry is a construction type widely used in many alpine regions in northern Italy. especially for vernacular and military buildings, as watchtowers. This kind of` masonry, results very weak under eccentric and horizontal loads if presents the lack of elements long enough to cross the thickness of` the masonry. In this paper is presented the design process for consolidation of “Lossetti Tower" — a medieval dry stone watchtower of about I4 meters high - using the technique of continuous basalt fibre (BF] stitching. First, a preliminary phase of knowledge of the building was developed. To better understand the masonry texture a 3D laser scanner survey of the tower was executed and to evaluate the teclmique effectiveness. Diagonal compression test on dry masonry specimens (reinforced and unreinforced), was done.
