This paper discusses an innovative steel fibre reinforced concrete structural system, developed to streamline the works of reinforcing for R/C interior joints. In this system, beam longitudinal bars on opposite sides of interior joints are neither lapped nor connected within the joints, but provided with head anchors using steel fibre concrete. The headed bars are anchored around the middle section of the joints. Steel fibres are added to plain concrete to enhance joints’ shear strength and anchor load capacity of the headed bars without joint shear reinforcement. The effect of using steel fibres is investigated through two tests. Pull-out tests of single headed bars were carried out. And, seismic structural performance tests of the proposed interior joints are carried out. A design method of the novel structural system is also suggested. It provides sufficient satisfaction as to the interior joint test results.
