Studies on stress-strain behaviour of concrete mixes confined with BFRP rebars

In the present study, stress-stain behaviour of confined concrete made with basalt fibre reinforced polymer bars (BFRP) were taken up. The stress-strain was studied for mixes steel rebars and BFRP rebars. confinement given in form hoops cylinders, 3 (0.8%), 4 (1.1%), 5 (1.3%) 6 (1.6%). addition fibres along enhanced compressive strength, indicating further effect concrete. It is observed that helpful lower confinements only. Beyond 1.1% confinement, any type doesn’t show on strengths. From all types mixes, it concluded ultimate load-carrying capacity strains at peak stresses are more up to confinement. has increased ductility both unconfined states
