Behavior of Exterior Reinforced Concrete Beam Column Joint with Strengthened Concrete and Diagonal Cross Bracings

Abstract

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