Models Of Historical Constructions:
A Temporal Perspective

Abstract
In this paper some of the studies developed by the authors in the last twenty
years in the field of numerical analysis and restoration of historical constructions
are presented, with the objective of having a temporal perspective. In all cases
the origin of every work was the appearance of several pathologies, that led to
structural studies in order to find out the causes of these pathologies and once the
way the structure worked and the origin of its problems was understood, the
consideration of the necessary restoration. According to our experience, the best
way to take into account this difficult and complex process, complementing the
engineer’s knowledge, is the use of numerical tools like the finite element
method. In each of the cases presented, 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. Comparison of the cases analyzed allows us to obtain several general
conclusions.
1 Introduction
Three cases of study are presented; they have been selected for being in our
opinion the most interesting. In the first one, from 1987, the computer aided
repair of the Pignatelli Church was presented. This was the first work, developed
by our group, in which numerical models are used. After that one appears the
identification of structural pathologies of San Martín Tower, the first work that
we did combining 3D CAD and visualization models as a previous step to
developing a finite element model. And finally the structural study of the
Basilica of Pilar in Zaragoza (Spain) is presented.
