This paper presents the first results of an experimental campaign performed – at the Laboratory of Materials & Structures of the University of Salerno (Italy) – with the aim to investigate the seismic performance of RC beam-columns joints strengthened with FRP and steel systems. The complete test matrix includes eight specimens realized to be representative of existing exterior beam-column subassemblies with inadequate seismic details. Of these, six were strengthened by using different FRP systems while the remaining ones were used as reference benchmark; once damaged, some specimens were also re-tested after being retrofitted with FRP. So far, six tests have been performed of which two were carried out on repaired beam-column joints. The obtained results have allowed to draw some criticisms related to the design of the joint FRP upgrading.

Abstract
This paper presents the first results of an experimental campaign performed – at the Laboratory of Materials & Structures of the University of Salerno (Italy) – with the aim to investigate the seismic performance of RC beam-columns joints strengthened with FRP and steel systems. The complete test matrix includes eight specimens realized to be representative of existing exterior beam-column subassemblies with inadequate seismic details. Of these, six were strengthened by using different FRP systems while the remaining ones were used as reference benchmark; once damaged, some specimens were also re-tested after being retrofitted with FRP. So far, six tests have been performed of which two were carried out on repaired beam-column joints. The obtained results have allowed to draw some criticisms related to the design of the joint FRP upgrading.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
