Abstract
In the frame structure, failures in beam-column joint mainly occur due to maximum bending moment and shear force. The reasons behind the failures due to conjection provision of reinforcement in the joints and concrete behave as brittle materials. This paper investigates the mechanical behaviours of interior beam-column jointsreinforced concrete and the application of hybrid steel fibrereinforced concrete composite (SFRC).In this study, three sets of interior beam-column joints were designed as per IS 1893code procedures for two bay five-story structures and detailed as per IS 13920 recommendationsand based on IS 456 recommendations. The first specimen was made with normal concrete and reinforcement detailed as per IS 13920,the Second specimen was prepared with 1% of Steel fibre (0.5%Crimbed and % 0.5 Hooked end) and reinforcement detailed as per IS 456.The third specimen was moulded with 1%(0.5%Crimbed and % 0.5 Hooked end) fibre reinforcement detailed as per IS 13920. The model was developed by considering the 1/5thscale of the prototype and was tested under cyclic loading. Thebehaviour of the jointswas examined in terms of load carrying capacity, deflection, ductility and energy observation. The study concluded that increased of energy absorption capacity and ductility properties of the interior beam-column joint. The experimental results indicated that fibre reinforced concrete is an innovativesolution to conventional confining reinforcement.
