Modelling on Reinforced Concrete Exterior Joint with Simplified Detailing Technique by Using Coupler Bar

Abstract

ṣThe present study focus on structural response of the Reinforced Concrete (RC) beam-column joint through numerical studies. For this study, totally two groups of reinforcement details are considered and named as “EJ-SFC” and “EJ-IS456”. The proposed coupler joint specimen (EJ-SFC) is compared with the standard detailed specimen that is design and detailed by IS 456-2000. To simulate each group of the specimen, a full 3D Finite Element Modelling (FEM) analysis has been carried out by using ANSYS 14.5 software. All groups of joints were tested under reverse cyclic loading. The outcome of the Finite Element Analysis (FEA) findings were presented in terms of load - deflection plot and compared with previous experimental results. The FEA and experimental results showed that the performance of the proposed coupler joint specimen was superior in ductile behaviour than that of EJ-IS456 specimen.
