Abstract

— Beam column joint is an important component of a reinforced concrete moment resisting frame and should be designed and detailed properly when the frame is subjected to earthquake loading. Failure of beam column joints during earthquake is governed by bond and shear failure mechanism which are brittle in nature. Modern codes provide for reduction of seismic forces through provision of special ductility requirements. A beam column joint has been moulded to the scale of 1:1.5 and the model has been subjected to cyclic loading to find its behavior during earthquake. The earthquake resisting structure is G+11 and has been analyzed using the Seismic Coefficient Method. This paper presents a synthesis of strengthening design of reinforced concrete beam and column by replacing it with Ultra High-Performance Fibre Reinforced Concrete.
