Data analysis finalised to the calibration of vulnerability, damage and cost and reconstruction models for residential and strategic buildings (In Italian)
Molise Region has been in charge of the post-disaster reconstruction process for the municipalities of Campobasso district, after 31 October 2002 seismic event. A Delegated Commissary has been nominated and has developed the O.C.D. n.13/2003 provisions, fixing the criteria and the guidelines for the reconstruction processes of public and strategic buildings, infrastructure systems, residential and commercial buildings. The design documents produced during the reconstruction process and the damage surveys collected during the emergency phase, represent an extremely useful source of information for the comparison, calibration and integration of the models currently used at a different level of detail and precision for the: 1) vulnerability assessment, 2) the damage estimation, 3) the cost estimation of the resources necessary for the reconstruction process. In this work, intended to be the first step of a wider analysis, data and information about damage observed and estimated reconstruction costs have been extracted from the PPS synthetic database and compared with the ones resulting by the implementation of the macroseismic vulnerability method. On one hand, PPS damage data have been used to evaluate the reliability of the damage distribution resulting from the implementation of the macroseismic method for an essentially numerical and typological characterisation of the built-environment. On the other hand, the PPS costs for reconstruction have been compared with the ones resulting from the simulated scenario by the use of cost models currently implemented in the framework of territorial scale risk analysis.
