ABSTRACT
ENEA, the Italian Civil Protection 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. A permanent accelerometric array has been designed and installed as part of the Seismic Observatory of the Italian Civil Protection. It was designed after a detailed study of the expected dynamic behavior of the structure and then installed and tested by recording ambient vibrations and weak motion effects also using a temporary array.The experimental results were compared with those obtained by means of a finite element model. Thus, linear and nonlinear analysis allowed to evaluate the seismic safety of the structure. All the steps of the modal identification, the model updating and the seismic analysis are shown in the paper.
