The study of the dynamic behavior of masonry arches and vaults is of paramount importance for several reasons: the evaluation of the seismic capacity; the determination of failure modes; the determination of the ductility and of behavior factors; the design of effective strengthening interventions, like for example by employing Fiber Reinforced Cementitious Matrix (FRCM) composites. Despite this, the literature still lacks a sufficiently large number of contributions on this subject, especially for what concerns either experimental study or reinforced arches. In this context, this paper, starting from the data of full-scale dynamic tests performed on unreinforced and Glass-FRCM reinforced Apulian tuff masonry arches, proposes some interesting observations on the dynamic behavior of masonry arches
