This paper presents the continuation of research considering the analysis of reinforced concrete bridge knee joints subjected to in-plane seismic loads. Strut-and-tie models incorporating rational joint force transfer mechanisms were developed to capture the non-linear inelastic response measured in four large-scale bridge knee joint tests. These models corresponded to different joint reinforcement detailing types and were analysed with Drain-2DX using non-linear truss elements. Obtained results were in satisfactory agreement with the measured displacement envelopes.
