Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 6,   Pages 729-743 doi: 10.1007/s11709-022-0854-9

Abstract: Three-point bending tests were carried out on nineteen Reinforced Concrete (RC) beams strengthened withThe FRP contribution to strength on beams having the same strip width to spacing ratios could be affectedThe FRP contributions to strength were less on beams with stirrups in comparison to the tested beamsStrengthening RC beams using FRP could change the failure modes of the beams compared to the referencewere assessed by using a limited number of beams available in the literature.

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: ductility in this material and the quasi-brittle behavior of concrete, FRP-reinforced concrete (FRP-RC) beamsBecause the limited deformation capacity of FRP-RC beams depends on the ductility of their compressionA control beam and four beams with different PCCBs were cast and tested under four-point bending conditionsThe goal was to find an appropriate PCCB for use in the compression zone of the beams, which not onlyimproved the ductility but also changed the failure mode of the beams from shear to flexural.
