BEHAVIOR OF EXTERIOR R.C BEAM COLUMN JOINT WITH STRENGTHENED CONCRETE AND DIAGONAL CROSS BRACINGS

Reinforced concrete moment resisting structures everywhere throughout the world is in necessity of quick actions for overhauling their execution level to survive the seismic loading impacts. Failure of beam column junctions are identified as the central cause of failure in moment resisting frames during seismic loads. Successful and economical techniques are required to improve joint structural properties and ductility of structures. In present work the seismic behavior of beam column joints with Diagonal cross bracings and strengthened concrete is contemplated. Performance of beam column joints with reinforcement specifications as per IS 13920:1993 and IS 456:2000 along with diagonal cross bracings, strengthening of concrete by using glass fibers and GGBS are studied in this exertion. The outcomes in this study illustrates that the provision of additional diagonal cross bracings and strengthening of concrete shows improvement in structural properties like load carrying, energy dissipation capacities and ductility which eventually improves the seismic behavior of beam column joint
