The double calotte dome of the Treasure of St. Gennaro's Chapel in the Cathedral of Naples has been analyzed by means of an interdisciplinary approach regarding a detailed historical analysis, problems of surveying the dome and a detailed structural assessment. The intention of the present work is to perform a preliminary investigation, by means of a numerical refined Finite Elements Model, on the historical phases of this structure, to have a clear knowledge of its vicissitudes and to check the reliability of the model to predict the dome behavior. Looking at the various numerical phases outcomes it is clearly seen that the dome underwent effective consolidation interventions: the position of the chains were accurately identified, and the need to reduce some specific weights was rightly specified. Once a reliable model is generated, it is possible to completely simulate the behavior of historical structures after a newly designed intervention or when subjected to different and severe types of load, e.g. seismic loads.

Abstract
The double calotte dome of the Treasure of St. Gennaro's Chapel in the Cathedral of Naples has been analyzed by means of an interdisciplinary approach regarding a detailed historical analysis, problems of surveying the dome and a detailed structural assessment. The intention of the present work is to perform a preliminary investigation, by means of a numerical refined Finite Elements Model, on the historical phases of this structure, to have a clear knowledge of its vicissitudes and to check the reliability of the model to predict the dome behavior. Looking at the various numerical phases outcomes it is clearly seen that the dome underwent effective consolidation interventions: the position of the chains were accurately identified, and the need to reduce some specific weights was rightly specified. Once a reliable model is generated, it is possible to completely simulate the behavior of historical structures after a newly designed intervention or when subjected to different and severe types of load, e.g. seismic loads.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
