SEISMIC RELIABILITY OF THE ABRUZZO HOSPITAL SYSTEM AND UPGRADING STRATEGIES

2 SUMMARY A model for the regional hospitals system behavior in case of a seismic event is developed. The aim is the evaluation of the vulnerability of the system as well as the selection of the best intervention strategy for the retrofitting of the hospitals so as to minimize the cost benefit ratio and to evaluate the effect of different post-earthquake emergency measures like the use of camp hospitals. The efficiency of the system is measured in terms of mean distance to be cured for persons injured by the earthquake. In a previous work by the authors (Nuti and Vanzi, 1998c) a common fragility law had been assumed for all the hospitals in Abruzzo because of lack of information. This information is now available, since the vulnerabilities of the Italian hospitals have been computed and presented (Nuti et al., 1998a) in a simplified though rather accurate way. The new results thus obtained are shown and compared with the previous ones. They allow to clearly indicate the most convenient interventions
