Simplified seismic analysis of ancient churches at a territorial scale

An overview of some simplified methods for assessing the seismic performance of ancient churches is presented in this paper. In particular, the simplified methods proposed by the current Italian directive containing the guidelines for assessment and reduction of cultural heritage seismic risk are analyzed. These methods have an increasing precision level and they may be applied as well in sequence at a different scale for screening and identifying the present priorities and, consequently, for designing the required interventions. The work presented in this paper concludes showing the applications on some case studies, too.
