Experimental data for the calibration of a nonlinear numerical model for describing the response of masonry constructions under cyclic loading

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.
