AB  - Current researches have demonstrated that the partial confining design by discrete strips is apromising and economic alternative to the full strengthening technique. In this connection, this study consists toevolve a new sustainable technique for confining concrete columns under axial compression. The proposeddesign technique consists to embed discontinuously hexagonal fibers reinforced polymer (FRP) strips andwrapped the outer concrete partially using external circular FRP strips. A detailed experimental program wasrealized on standard dimension composite-encased concrete cylinders under compressive loading until failure toevaluate the axial compressive strength and the corresponding failure mode of the reinforced concrete. Inaddition, mechanical characterization tests were performed to provide the behavior laws of used raw materials.The emphasized experimental results namely: stress versus hoop and axial strain curves and the rupture patternsof all tested samples indicate clearly an improvement on the stiffness, axial stress and strain of the reinforcedconcrete columns compared to conventional unconfined ones.
