FLEXURAL BEHAVIOUR OF BEAMS WITH HYBRID CONFINEMENT

This study represented the experimental results of FRP strengthened HSC beams with internal confinement. The first crack load, yield load, ultimate load, deflection at first crack load, deflection at yield load, deflection at ultimate load and ductility indices were the study parameters. The test beams of cross section 150x250 and 3000 mm in length were cast and tested. The beams were subjected to two-point loading and tested up to failure. Deflections, crack width, spacing of cracks and number of cracks were measured at all stages of loading. The results revealed that the ductility performance improved considerably through the introduction of internal confinement mechanism.
