A Methodological Approach to Evaluate Seismic Vulnerability of Masonry Cathedrals

The seismic analysis of historical and monumental masonry buildings, especially churches cathedrals, is challenging expensive. These difficulties are mainly related to complex geometry the mechanical modelling historic structures. This paper aims show methodological approach evaluate vulnerability Masonry Cathedrals by analysis. numerical finite element model, modelled with solid elements, was optimised based on identifying primary dynamic properties performed in ambient excitations recorded a continuous monitoring system operation since 2015. We carried out linear analyses for model entire structure. also non-linear vaults, where damage concentrations were detected after various events. structural aimed estimate time histories acceleration at connection areas between vaults vertical results consistent maps identified actual Furthermore, procedure showed an excellent ability reproduce accurate response.
