A comprehensive structural study of the Basilica of Pilar in Zaragoza (Spain)

摘要

The Basilica of Pilar, located in the city of Zaragoza, is one of the best known Spanish cathedrals. Several domes of this church contain frescoes authored by Francisco de Goya, and some of them have suffered damage in the past decades due to various pathologies, in particular the frescoes of dome Regina Martirum are being restored at the present time. A set of structural models was developed and validated with the aim of simulating the current structural state, their security level and the relationship between the structural behaviour and the damage observed. The numerical models have been formulated applying the FEM in linear and non-linear theory, considering the constructive process and the reinforcement works added to the structure along with their history.
