“…Due to a lack of maintenance, the masonries of old buildings are frequently in a poor state of conservation [10,21,44]. This masonry typology presents very different characteristics; some are made of a single leaf, while others have multi-leaf.…”

Monuments are by definition unique buildings which cannot be reduced to any standard structural scheme. In this study, we have used quasi-static loads, which is common practice in many finiteelement (FEM) analyses of masonry structures. Thus it is difficult to evaluate their reliability, because in addition to the many uncertainties that exist in all 'old' buildings, no statistics on the behaviour of similar buildings are available. In this paper we describe a study of the structure of the chapel of San Salvador de Valdediós and proposals for its restoration. The non-linear analysis is based on the application of FEM to each of the stone blocks in this ancient structure. The blocks are assembled side by side using 'contact elements' in order to reproduce the mechanical behaviour of the mortar and the surface conditions of the blocks, some of which are seriously damaged. A clear understanding of the structural behaviour, based on sophisticated analysis tools, can reduce the extent of the remedial measures necessary for the restoration of the chapel vault and portico. In this case, severe damage to the chapel vault has affected the portico, resulting in the possibility of a structural collapse. Finally, based on the numerical results obtained for different load cases and hypotheses, we propose a solution for the repair of this part of the chapel using either traditional materials or compatible substitutes.

A B S T R A C TThis paper shows the application of two innovative infrared thermography (IRT) methods for the evaluation of water transport phenomena through the outer layers of porous stone materials. An infrared camera measured: (a) the moisture stain due to the water absorption after having spilled a drop on the stone surface and (b) the "moisture ring" around the damp surface, after the contact between a soaked round sponge and the stone surface. The time of spreading and the geometric shape of the damped area depend on the porosity of the stone material and are useful to characterize the physical stone features. In addition, monitoring the evolution of the moisture ring by IRT allows implementing and optimize the data coming from protocols of water repellent products with data coming from the "contact sponge measures". Moreover, moisture ring test links IRT and laboratory tests characterizing the transport phenomena of liquid and water vapour in porous building materials. Thirty specimens of marble, calcarenite and sandstone were tested with steady methods (dry index and water absorption by capillarity), that validated the data provided by the two innovative IRT techniques.
