Experimental Seismic Behaviour of Historical Buildings: the Palazzo Marchesale in S. Giuliano Di Puglia, Italy

Abstract eng:
Identification of dynamic characteristics of historical buildings is an important step that is necessary for two basic reasons: to assess possible dynamic behavior of such complex structures during strong events and to gain experience on the dynamic behavior of historical buildings such that the experience and database can be used in future design and analyses. Actually, data on dynamic behavior of complex structures such as historical buildings are scarce. The databases are in general obtained from dynamic testing of structures (forced vibration, ambient vibration, etc), and from analyses of data from instrumented structures. With this purpose, ENEA, in accordance with the Italian Civil Protection Department and the Municipality of San Giuliano di Puglia organized a research project for seismic monitoring of relevant structures in the framework of the reconstruction of San Giuliano di Puglia, Italy. Among the monitored buildings there is the Palazzo Marchesale, an old masonry structure hosting the new City Hall. Some low-intensity seismic events have been recorded up to now, which allowed analyzing the seismic behavior under events of different magnitude and distance from the site. The experimental results have compared with those of a numerical analysis.
