Beam column joints of a reinforced concrete structure need special attention due to their highly complex behavior under seismic loads, which is marked by a combination of large shear forces, diagonal tension and high bond stresses in the reinforcement bars, all brittle mode of failure. An experimental investigation of the behavior of Corner beam column joints with detailing as per IS 13920: 1993 under seismic conditions is presented in this paper. The experimental study on Corner beam column joint of a multistory reinforced concrete building (G+ 4 storey's) in Salem Zone falling under the seismic Zone – III has been analyzed using STADD.pro. The specimens were designed for seismic load according to IS 1893(Part I): 2002 & IS 13920: 1993. The test specimen is reduced to one fifth model of beam column joint from prototype specimen. Column confinement and beam stirrups are provided closely in joint region according to IS 13920: 1993. The test specimens were evaluated in terms of load displacement relation, ductility, load ratio and cracking pattern.
