Abstract
The aim of this paper is to develop an update of the existing subsoil model for the site in San Giuliano di Puglia (Italy), where the primary school F. Jovine collapsed after the 2002 Molise earthquake. To this end, we performed a site response back-analysis using the data from seismic stations recently installed in the village to obtain a proper input motion and to validate the results of the computations. To implement a 1-D subsoil model, we scrutinized the geotechnical tests recently performed in the area as well as previous studies conducted on the same site. Then, we performed a parametric 1-D site response analyses varying shear wave velocity profiles and the depth of the bedrock. The most appropriate subsoil model, characterized by higher soil stiffness, results substantially different from the one proposed in previously published studies of the seismic response of the city.
