Mechanical anchorage has been developed as an answer to bent-anchorage problems recently, and the authors have proposed the design criteria on reinforcement detailing of R/C exterior beam-column joint. In this paper, the application of highstrength material is studied through various experiments, in which compressive strength of concrete, the effect of anchoragelength of beam reinforcement, depth of column, and the quantity of shear reinforcement in beam-column joint, are examined. Consequently, the authors clarify that proposed design formula can be applied for estimation of anchorage strength of beam reinforcement and shear strength of beam-column joint, as well as design criteria on structural performance of R/C exterior beam-column joint.
