Val d’Aran is located in the north side of the Spanish Pirineo, between Spain and France. There we can find a group of Romanic churches built on XIIth Century, which presents large geometrical deformations of more than 10% its initial form. The basilical churches were initially covered with timber roofs. Later these were replaced by barrel vaults supported by non-monolithic columns with circular section (Puig i Cadafalch 1908).
It is particularly interesting the church of Santa Maria d’Arties (XII-XIII), which large deformations were previously discussed by several authors as Villanueva (1974), Bassegoda (1974), Sáez (1976) and Polo (2009). The work presents the analytical assessment of the masonry structure of this Romanesque church, where the constructive materials are working to the limit. It has been performed a limit analysis by means of thrust-lines and a FEM calculation to assess the large movements of the structural elements and to determine its possible causes.
