• Beam-column joints are the critical zones of the RC moment-resisting frame. These joints govern the ductility and strength performance of the moment-resistance structural frame, and the addition of fibres can improve these properties. This article focuses on evaluating the behaviour of beam-column joints with steel fibre-reinforced concrete subjected to reverse cyclic loading. Three types of specimens with different reinforcement detailing were provided and evaluated. Type A specimen with joint detailing as per Indian ductile detailing code (IS 13920 – 2016), Type B specimen was detailed as per IS 456 and SP 34 with steel fibres in the joint region, and Type C specimen with ductile detailing and steel fibres in the critical zone of the beam-column joints. Seismic loading at the beam end is controlled by reverse cyclic displacement. The present work aims to create a three-dimensional numerical model with the ABAQUS/CAE (6.14) software. The concrete damage plasticity (CDP) model was used to define the nonlinear properties of concrete by analysing the structure's response. The results show that 1.5% of steel fibre-reinforced concrete with ductile detailing offers better performance. The average difference between the finite element analysis and experimental testing results was lesser than 10%.
