Abstract

A sequence of ground shakings occurred from October, 1831 to March, 1832 in Central Italy. Due to the high intensity and the repetition of the events, the Basilica of Santa Maria degli Angeli, Assisi was damaged severely, suffering the collapse of the vaults of central and left naves. After the first emergency interventions, engineer-architect Luigi Poletti (1792-1869) was appointed to design the retrofitting and restoration works. From an architectural point of view the works carried out by Poletti were rather respectful, but from a structural point of view they introduced interesting innovations. Contrary to the collapsed construction, Poletti rebuilt the roof over the central nave with an original raised tie beam and iron braced truss, not resting on the below vault, while the vault had now a tapered transversal section. Poletti's solution are considered from a structural point of view, performing numerical simulations by means of limit analysis and finite element models, with reference to his original drawings, to previous and following earthquake damages, and to contemporary technical literature. © 2008 Taylor & Francis Group, London.
