EXPERIMENTAL STUDY ON STEEL FIBER REINFORCED CONCRETE IN BEAM-COLUMN JOINT

An experiment is reported regarding the effect of using steel fibre reinforced concrete in exterior quarter scale corner beam column joints cast by using M20 concrete. The Beam column joint has been analysed using STADD Pro under seismic zone III. All the specimens were designed and casted according to Bureau of Indian Standards, Tested under reversed cyclic loading. All specimens were designed as per IS 456-2000 except the second specimen which was designed and casted as per IS 1893: (Part1) 2002 and detailed as per IS 13920:1993. The remaining three specimens were designed as like first one but using 0.5 % of steel fibers in different face length from beam column joint. The parameters that are to be determined from the experiment include load vs displacement cycle, energy dissipation, Load vs displacement curve, ductility, crack pattern. The beam column joint with Ld -50mm (BCM IV) FRC from face of joint have best performance considering the strength, energy dissipation capacity and ductility factor
