Study on Reinforcement Detailing in RC Structures to Avoid Failure at Beam-Column Joint

Abstract

Numerical investigation on a reinforced concrete (RC) frame structure is carried out to attain a ductile failure of structure by providing an effective detailing of reinforcement. Structure is made to undergo ductile failure by inducing plastic hinge in the beams instead of beam column junctions. A two dimensional G+9 floors frame with 4 bays is analyzed using STAAD.Pro for all kinds of load combinations, which includes earthquake and wind loads. The beam having maximum bending moment is considered and the reinforcement arrangement is done in such a way that the hinges are formed in the beams instead of beam column junctions which cause the structure to fail locally and not globally.
