Abstract
The research about the Pompeian building would study in details a specific period of the city history : between the earthquake in 62 a. C. and the volcano eruption in 79 a. C. Through the analysis of a meaningful building for the public life in Pompei it intend to investigate the knowledge of Romans about strengthening and building techniques. According to this, which models or materials were used in a seismic region. The single structural element is an object studied as a part of a system whole reacting with ‘firmitas’ (strength). Successively, the restoration in the XIX century, show an example of the interpretation given to the shape of the building. The loss of ruins in this site and the absence of materials nearby, could mean that the history of the Basilica may not have had a collapse due to the earthquake. The seismic risk exposure of such an archaeological site urges studies about restoration techniques and preservation of archaeological materials. This paper presents the results of a 3D F.E.M. analysis of a single column of the basilica as it has been virtually reconstructed. A detailed analysis has been conducted involving a discrete elastic model of single blocks and mortar joints. The pattern of the column is layered, and the global response of the column is strongly dependent on the order and in plane orientation of the layers. A detailed analysis of this new practice of staggered blocks has been investigated. The result of the analysis is the numerical evaluation of the global improvement of a single column behaviour with respect to the traditional arrangements. Subsequently the seismic response of the entire basilica can be assessed only once the single column behaviour is known.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
