Ductility improvement of GFRP-RC beams using precast confined concrete block in compression zone

Frontiers of Structural and Civil Engineering doi: 10.1007/s11709-023-0968-8

Abstract: However, owing to the lack of ductility in this material and the quasi-brittle behavior of concrete,FRP-reinforced concrete (FRP-RC) beams, even with flexural failure, do not fail in a ductile manner.FRP-RC beams depends on the ductility of their compression zones, the present study proposes using a precastconfined concrete block (PCCB) in the compression zone to improve the ductility of the beams.
