This paper presents a preliminary study on the behavior of beam-column joints designed with high ductile fiber-reinforced mortar (HDFRM). There have been a number of previous studies, which suggest that the use of high ductile material significantly enhanced ductility of structural elements even without shear reinforcements involved. The present study emphasizes increased load-carrying capacity and ductility by employing high ductile material, with which concrete in the beam-column joint was replaced. The specimens designed with HDFRM (HJSRP-with stirrups, HJRP-without stirrups) in addition to the control specimen (HJC) were cyclically tested. Test results indicated more stable hysteresis behavior, high load carrying capacity, and distributed crack pattern of specimens HJSRP and HJRP when compared to the control specimen.
