Sažetak
This paper presents an experimental study of a strengthened pointed arch subjected to horizontal sinusoidal excitation on a shaking table. The geometry of the arch was selected to represent the geometry of typical Gothic vaults found in small single-nave village churches in Istria with preserved medieval wall paintings. The arch model was constructed from identical timber blocks with dry joints, while the reinforcement (duct tape) was applied either at extrados or at intrados of the arch. The aim of this study was to document the dynamic behaviour of pointed arches strengthened with composites, since there is a lack of experimental tests on this type of geometry. Contactless optical measuring system was used to monitor the openings between the blocks, since conventional sensors are difficult to apply. Two high-speed cameras made it possible to record the formation and closure of hinges between the blocks. Due to strengthening some hinges were hindered and consequently the seismic capacity of the arch was significantly improved.
