Abstract
Masonry bridge with five long span arches: computer modelling analysis of failures and repairs R. Roccati Department of Structural Engineering, Politecnico di Torino, Italy Abstract Within the framework of research on vaulted structures, this study proposes a structural analysis of a special case study: a 19* century five-arch masonry bridge (fig. 1) on the Cervo torrent near Buronzo (Vercelli) in Italy. Thanks to careful surveys and the retrieval of the original design project, it proved possible to work out a mathematical model able to take into account the different structural elements that were typical of late 19* century masonry bridges: foundations, piers, abutments, arches, tympanums and filling. A step-by-step analysis made it possible to eliminate from the masonry the zones in tension and work out a reliable model, so as to gain an understanding of the real structural behaviour of the bridge, both in its original configuration (before and after the damaging phenomena), an
