Two Steps Procedure for the Finite Elements Seismic Analysis of the Casamari Gothic Church

The structural analysis of historic masonry churches subject to earthquakes is commonly based on two distinct approaches: that the global response seismic actions and local a priori pre-determined collapse mechanisms. This conventional decoupling problem due difficulty addressing vulnerability individual parts from modelling whole. aim this work establish link between behavior church assessment mechanisms, re-evaluating value modal be associated with non-linear assessment. With aim, steps procedure proposed, where: first step detection main vibration modes whole building identification bi-dimensional macro-elements are responsible for overall vulnerability, while second step, finite element previously identified macro-elements, evaluate failure pattern caused by earthquakes. will applied case study Casamari Gothic in Veroli (Italy).
