Territorial analysis of seismic performance of ancient churches: Methods and application to case studies

In this paper two simplified methods are presented in order to assess the seismic performance of a set of Italian ancient churches. The methods applied are characterized by an increasing refinement level, requiring only some qualitative information in order to evaluate representative indexes of global seismic response. The methods considered may be applied for screening and identifying the current priorities at a territorial level and for planning, where necessary, more refined analysis for evaluating seismic response and required interventions (if necessary). Finally, applications to case studies are illustrated and compared with the aim of highlighting the limitations of the methods considered.
