In this paper the effectiveness of the application of an hemp biocomposite reinforcement at the extrados of a masonry barrel vault was investigated. To this aim, two specimens of unreinforced (UV) and reinforced (RV) masonry vaults were built having the same geometry with brickwork material and subjected to shaking table seismic tests. The comparison of the dynamic behavior between the two specimens was carried out by increasing the intensity of the seismic input, which was simultaneously applied on both the structures. The evaluation of the progressive damage induced by the seismic input was observed by visual inspections and natural frequencies decay estimated by experimental dynamic identification through the application of Operational Modal Analysis (OMA) techniques.

The comparison of the dynamic behavior between the two specimens was carried out by increasing the intensity of the seismic input, which was simultaneously applied on both the structures. The evaluation of the progressive damage induced by the seismic input was observed by visual inspections and natural frequencies decay estimated by experimental dynamic identification through the application of Operational Modal Analysis (OMA) techniques.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
