One of the crucial issues in the still open problem of seismic analyses of masonry
constructions is the study of the structural capacity for cyclic loadings; the difficulties are
even more pronounced when constructions embedding curved elements like arches, vaults and
domes have to be studied. In order to develop effective nonlinear numerical models, the latter
have to be capable of representing the relevant aspects of the experimental behavior, and the
mechanical parameters of the model have to be carefully calibrated with reference to suitable
experimental test results. In this paper the outcomes of experimental tests on a tuff masonry
arch under cyclic loading are proposed and discussed, along with the results of experimental
tests on the masonry materials (blocks and mortar) aimed at determining the compressive,
flexural and shear behavior.
