EXPERIMENTAL EVIDENCE OF UNCERTAINTY IN SEISMIC RESPONSE OF MASONRY VAULTS

This paper is focused on the correlation between the experimental results and the theoretical results. The experimental part is relevant to dynamic experimental tests performed on some masonry arches placed on a shaking table facility at the Laboratory of the ENEA Research Center. The theoretical part consists of two elaborations, the first one sees the elaboration of a model NT of the masonry structure, by means of some calculus codes made by the researchers of the University of Naples “Federico II”, in the second part the implementation of the calculus code and of the recorded data is developed for the comparison of the theoretical model and the experimental one. The analysis puts in evidence that the static degradation of the simulacra is much faster than in the seismic response, probably thanks to kinetic energy absorption that helps the structure to resist inertia forces.
