A parametric study on moment redistribution in FRP-strengthened continuous RC beams

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Research has shown that despite the benefits of using Fibre Reinforcement Polymer (FRP) in increasing the shear or flexural strength of Reinforced Concrete (RC) members, there are concerns about the technique in some conditions. Ductility is one of the issues that still need to be investigated further, as research has shown that the brittle nature and premature failure of FRP materials added to statically indeterminate RC beams can limit the ductility or reduce the plastic rotational deformation prior to collapse. In this paper, an analytical model is proposed for measuring Moment Redistribution in continuous RC beams. A parametric study has been carried out to examine the behaviour. The results show the ability of these structures to redistribute moments but its level strongly depends on the amount and configuration of FRP used for the strengthening of the structure.
