Comparative Seismic Risk Assessment of Basilica-type Churches

This paper discusses the seismic risk assessment of the Basilica of San Francesco in Italy according to the provisions of the Italian Guidelines (DPCM2011). A comparison between the results obtained with local and global approaches is reported, based on a knowledge process aimed to characterize the geometric and mechanical parameters required for a reliable structural analysis. To perform the global analyses the finite element technique was employed, with proper assumptions to account for the nonlinear behaviour of masonry. Illustrating a case study, the paper critically discusses about the employability of pushover analysis methods for the seismic assessment of Basilica-type churches.
