Summary

In this paper a comparison between two non – linear finite element models whichhave been developed for the analysis of masonry arches is presented. According to the firstmodel, the geometry of the arch is divided into a number of unilateral contact interfaces whichsimulate potential cracks. Opening or sliding for some of the interfaces indicate crack initiation.The second model initially uses two-dimensional finite elements for the simulation of the arch.When tensile stresses appear, the corresponding elements are replaced by non linear gap elementswhich represent cracks. In both models the fill over the arch is taken into account. Moreover,the ultimate load and the collapse mechanism have been calculated by using a pathfollowing(load incrementation) technique. Both models are developed and applied on a realscale masonry arch, so that the results can be compared.
