The validation between experimental and modelled hysteresis loops is a preliminary work in determining the dynamic behaviour of the beam-column joints under earthquake excitations using Ruaumoko 2D program. However, this paper only focuses on accurately modelling the hysteresis loops of corner and interior beam-column joint using the HYSTERES Program. The corner and interior beam-column joints were designed using Eurocode 8 and equipped with unbonded fuse-bars which acts as passive energy dissipators. The hysteresis loops were modelled based on the input parameters obtained from the experimental hysteresis loops. From the HYSTERES program, the Pampanin Reinforced Concrete Beam-Column Joint was chosen to represent the hysteretic behaviour (load versus displacement) for overall seismic behaviour of these joints. The lateral strength capacity, stiffness, ductility and equivalent viscous damping from experimental and modelled hysteresis loops were then compared, and the percentage difference from both hysteresis loops was calculated. Based on the outcomes, there are some parameters which have shown good agreement, and this proves the effectiveness of using HYSTERES program in modelling the hysteresis loops of the beam-column joints.
