Development of a seismic risk mitigation methodology for public buildings applied to the hospitals of Basilicata region (Southern Italy)
Abstract This paper deals with the development of a procedure aimed at defining a seismic risk mitigation strategy for public buildings in terms of prioritization, time required and funds. The procedure is based on a global risk index involving the entire building stock under study thus facilitating an examination of risk variation over time up to its final value. Relationships between the current seismic capacity–demand ratios and the required strengthening costs (cost models) have been developed. Each of the assumed cost models has a different target in terms of capacity–demand ratio to be obtained after strengthening, basically ranging between full retrofit and upgrading. The procedure has been applied to 69 hospital buildings located in Basilicata region for which the vulnerability data was available as a result of a large assessment program set up by the regional government. Priorities have been defined on the basis of seismic capacity, local hazard and number of human beings possibly involved (exposure). The results of different strengthening strategies have been outlined with a special focus on the pros and cons of the upgrading strategy with respect to various retrofit strategies. The procedure may be applied to different categories of public buildings by properly modifying some input parameters and partially redefining criteria for prioritization.
Highlights Hospitals play a crucial role in the aftermath of a seismic event. A procedure to define a seismic risk mitigation methodology is proposed. Relationships between intervention costs and capacity–demand ratios are developed. Criteria to define priorities for seismic intervention are developed. The procedure has been applied to the hospitals of an Italian region.
