EXPERIMENTAL SEISMIC ANALYSIS OF MONUMENTS FOR RISK MITIGATION

An experimental investigation, at the moment in progress, for the evaluation of the seismic vulnerability of a monumental structure and the effects of some reinforcement devices are presented. Referring to this monumental structure, that is a church, the authors obtained the dynamically identified analytical model and recognized that the drum-dome system was one of the macro-elements with highest risk. This result was obtained by analyzing the linear behaviour. In order to study the nonlinear behaviour, tests on reduced scale models were necessary. The models, with and without risk mitigation reinforcements, were subjected to seismic input with rising intensity in order to know the effects …
