EXPERIMENTAL SEISMIC ANALYSIS OF MONUMENTS FOR RISKMITIGATION

Research output: Contribution to conferenceOther

Abstract

An experimental investigation, at the moment in progress, for the evaluation of the seismic vulnerability of amonumental structure and the effects of some reinforcement devices are presented. Referring to thismonumental structure, that is a church, the authors obtained the dynamically identified analytical model andrecognized that the drum-dome system was one of the macro-elements with highest risk. This result wasobtained by analyzing the linear behaviour. In order to study the nonlinear behaviour, tests on reduced scalemodels were necessary. The models, with and without risk mitigation reinforcements, were subjected to seismicinput with rising intensity in order to know the effects of the reinforcements themselves. A study was alsobegun in order to determine the ultimate load and ductility resources given by the various types ofreinforcements used. Through the paper some details of the above investigation are discussed and the lastresults are presented.
