UniSa - IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThis paper presents an experimental and numerical investigation on the load bearing capacity of 6.5m-long RC beams strengthened with prestressed CFRP strips with gradient anchorage. This technique eventually leaves a purely concrete-epoxy-strip connection without any remaining mechanical devices such as bolts or plates. Laboratory tests were carried out in the framework of an industry-based R&D project. Experimental testing consisted of a 6-point static loading procedure on four simply supported beams. Experimental results, such as force-deflection, force-strain curves, and failure modes, are presented. In a second step, a non-commercial finite element code is presented and applied to the previously presented testing configuration. Finally, the experimental results and the corresponding numerical simulations are compared.
