Abstract
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.
1 The building and their history
The Basilica of Pilar is one of the most important worship places in Spain. The
actual temple is a large and complex brick masonry construction, with
rectangular plan and measures about 100 m. long and 70 m. wide. Their
construction was long in the time and difficult [1]. In the current site, more than
a thousand years ago, a small Visighotic chapel had been built; later on became a
Romanesque church with cloister that will suffer posteriorly a Gothic
enlargement. Nevertheless, all the aforementioned constructions were of small
size compared with the huge extension which took place in XVII century when
the project of a baroque church was set up by the Spanish architect Ventura
Rodríguez. The central dome rises by the middle of XIX century, and the towers
of Ebro river facade are erected in 1940.
Figure 1 presents a sketch describing the position of each building along the
history, and Figure 2 shows plans and several views of the actual temple.
