Behaviour of Polypropylene and Steel Fibre Reinforced High Strength Concrete Exterior Beam Column Joint

Abstract

Abstract. The present work aims at studying the performance of polypropylene and steel fibre reinforced high strength concrete in exterior joint of beam-column. Individually and in combination, steel fibre with 0.25 %, 0.50 %, 0.75 %, and 1 % by volume of concrete and polypropylene fibre with 0.16 % and 0.32 % by volume of cement were induced into the concrete. The characteristics investigated are energy absorption capacity, displacement ductility and shear carrying capacity. From the obtained test results, it is concluded that 0.16% polypropylene fibre with 0.75% steel fibre in hybrid fibre composites show desired strength in all aspects of investigation.
