Abstract: Abstract Strengthening might be necessary for unbonded post-tensioned (UPT) concrete members to account for mistakes at the design stage or to solve construction errors. Various strengthening techniques have been developed that use carbon-fiber-reinforced polymer (CFRP)… read more here.

DOI: 10.1016/j.engstruct.2019.109927
Abstract: Abstract The neutral axis depth is adopted by many codes of practice as an indicator of flexural ductility to quantify moment redistribution in continuous prestressed concrete (PSC) beams. Moment redistribution, however, does not only depend… read more here.

DOI: 10.1061/(asce)cc.1943-5614.0000719
Abstract: AbstractBecause of the premature debonding of fiber-reinforced polymer (FRP) materials that results in a reduction in ductility, the problem of how to exploit moment redistribution (MR) in FRP-strengthened continuous reinforced concrete (RC) structures is unresolved.… read more here.

DOI: 10.1080/13287982.2021.1912518
Abstract: ABSTRACT Computing the moments in RC structures after the yield by linear elastic analysis can lead to an inaccurate assessment of the behaviour due to the nonlinear behaviour. Therefore, it can become necessary to use… read more here.

Moment Redistribution in Continuous Externally CFRP Prestressed Beams with Steel and FRP Rebars
Sign Up to like & getrecommendations! Published in 2021 at "Polymers"
DOI: 10.3390/polym13081181
Abstract: This paper assesses the impact of adopting carbon- or glass-fiber-reinforced polymer (CFRP or GFRP) instead of steel rebars on the redistribution of moments in prestressed concrete beams (PCBs) with external CFRP tendons. A numerical program… read more here.
