Summary

Two classes of out-of-plane failure modes of a masonry system composed of a façade wall connected with two sidewalls are investigated. These involve rocking, sliding, torsion failure and combinations of them. A rigid-perfectly plastic model with dry contact interfaces governed by Coulomb failure criterion is assumed for masonry walls. The macro-block modelling approach and the solution procedure adopted for the non-standard limit analysis are based on the assumption that all the possible relative motions among micro-blocks are concentrated along the cracks. Two limiting conditions for the ultimate load factor are kinematically computed by use of minimization routines. The influence of some geometrical parameters on the global resistance and the presence of an unrestrained horizontal floor system with different orientations are also investigated.
