Summary

The paper discusses the static behaviour and the seismic vulnerability of the Basilica of San Francesco in Arezzo (Italy). The vulnerability assessment of the Basilica was evaluated according to the provisions of the Italian "Guidelines for the assessment and mitigation of the seismic risk of the cultural heritage" (DPCM 2011) that identifies a methodology of analysis based on three different levels of evaluation (LV1, analysis at territorial level; LV2, local analysis and LV3, global analysis), according to an increasing level of knowledge. A detailed and careful knowledge process, which included an experimental in-situ investigation, enabled the characterization of the geometric and mechanical parameters required to perform a reliable structural analysis. The finite element modelling technique was employed to perform the global analysis (LV3), where the non-linear behaviour of masonry was taken into account by proper constitutive assumptions. Discussing the capacity of the Basilica to horizontal loads (evaluated together with the seismic expected demand), the paper critically discusses the employability of pushover global analysis for the seismic assessment of Basilica-type churches.
