NSCD∗ method applied to mechanical simulation of masonry in historical buildings using MOMA∗∗

This paper introduces a new approach for the mechanical modelling of historical monuments built of blocks. The computational method, * Non Smooth Contact Dynamics (NSCD), is used to simulate masonry as a large collection of bodies under unilateral constraints and frictional contact. The computational method, NSCD, within an architectural and archeological model, MOMA, **Models and Opticals Measurements in Architecture are merged in a single tool providing a interdisciplinary approach of historical buildings. The morphology and initial deformations measures are obtained by a photogrammetrical survey monitored by an architectural and archeological knowledge. The implementation of the model and experimental techniques are presented introducing an example of case study on the Tour Saint-Laurent of the ”Palais des papes” in Avignon (France).
