Planning seismic damage prevention in the old tows value and evaluation matters

Abstract

Only recently seismic prevention has come up in urban planning and considered as a significant part of the social capital of the urban heritage. Among the planning tools for reducing the vulnerability of urban fabrics, the Emergency Limit Condition (ELC) defines the fields which require widespread strengthening interventions in the buildings involved in resilient town units. The extent and intensity of such interventions can be graded so as to find an optimal ELC measure, taking the needs of the urban and human capital into account. In case of the old town centre of Ragusa, a model for analysing the seismic vulnerability of the built-up areas has been integrated with a model for a cost-revenue estimation in order to identify the conditions of the ELC dimensioning and to develop the relevant incentive system.
