The aim of the paper is to present the structural analysis of an important historical building: the San James Theater actually used as the Municipality House in the city of Corfù. The building is made of carves stones and is located in the centre of Corfu, Greece. The study deals with the structural identification of such structure through the analysis of its ambient vibrations recorded by means of very accurate accelerometers. A full dynamic testing was developed using ambient vibrations to identify the main modal parameters and to make a non-destructive characterization of this building The results of these dynamic tests will be used for the model updating of a complex FE simulation of the structure. This analysis may present several problems and uncertainties for this stocky building. Due to the presence of wooden floors, the local modes can be highly excited and, as a consequence, the evaluation of the structural modal parameters presents some difficulties. The paper discusses the experimental tests and compares the results with those obtained from the analysis of a preliminary FE model obtained using a commercial software.

Abstract
The aim of the paper is to present the structural analysis of an important historical building: the San James Theater actually used as the Municipality House in the city of Corfù. The building is made of carves stones and is located in the centre of Corfu, Greece. The study deals with the structural identification of such structure through the analysis of its ambient vibrations recorded by means of very accurate accelerometers. A full dynamic testing was developed using ambient vibrations to identify the main modal parameters and to make a non-destructive characterization of this building The results of these dynamic tests will be used for the model updating of a complex FE simulation of the structure. This analysis may present several problems and uncertainties for this stocky building. Due to the presence of wooden floors, the local modes can be highly excited and, as a consequence, the evaluation of the structural modal parameters presents some difficulties. The paper discusses the experimental tests and compares the results with those obtained from the analysis of a preliminary FE model obtained using a commercial software.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
