The objective of this study is to clarify the elasto-plastic behavior of beam-column joints of RC structures by using high-strength concrete and high-strength steel fiber reinforced concrete along with high-strength steel reinforcement and diagonal reinforcement in panel zone. Seven identical 1/2 scale models of cross-sectional interior beam-column joint specimens were prepared by using these materials. Pin supported axially loaded columns of the beam-column joint specimens were subjected to repeated cyclic anti-symmetric loading at both ends of the beams. From the results of the experiments, shear stress values for the panel zone were below the calculated values according to AU Design Guidelines for Earthquake Resistant RC Buildings Based on Inelastic Displacement Concept, since all specimens attained a shear failure of the joint after the beam yielded to flexural loads. The use of diagonal reinforcement and high-strength fiber reinforced concrete in panel zone shows a remarkable improvement in shear strength and ductility of the panel zone of the beam-column joint.
