Abstract

Retrofitting effects on the dynamic behaviour of S.Maria di Collemaggio E. Antonacci, G.C. Beolchini, F. Di Fabio & V. Gattulli DISAT, L'Aquila University, Italy Abstract The Basilica S.Maria di Collemaggio has recently been subjected to some small- scale repair work required after a recent earthquake in Central Italy; the structure has also been moderately strengthened. As preliminary step, a numerical analysis to predict and frame the effects of the work was performed by finite element models. Experimental research was also conducted to help calibrate the parameters of numerical models and, at the same time, to verify the actual behaviour of the church before and after reinforcement. The numerical and experimental analyses compared in this paper allow us to assess the consequences of the reinforcement and to appreciate the effectiveness of dynamic tests. 1 Introduction The Basilica S.Maria di Collemaggio is one of the most beautiful churches in Central Italy
