Numerical simulations of anchorage of reinforcement in RC beam-column joints are carried out using the three-dimensional Rigid Body Spring Model (RBSM). To investigate the effects of rebar clear spacing between longitudinal reinforcements in a beam-column joint, four simulations are carried out. The results show that rebar anchorage capacity decreases when the rebar clear spacing is smaller than the coarse aggregate size and when the beam’s and column’s reinforcements do not splice on the same plane. This indicates the presence of weak concrete between the closely-spaced reinforcements. Further simulations are also carried out to confirm the benefits of transverse reinforcement to enhance the anchorage of beam and column reinforcements at beam-column joints. The simulations confirm this beneficial effect and show good agreement with experimental data in terms of anchorage capacity, crack patterns, and failure modes.
