This paper presents seismic test results of hinge isolated reinforced concrete beams with/without openings at beam-ends. At the hinge region of the beams, main bars were un-bonded in order to reduce damage of concrete and supplementary main bars were arranged to resist bending moment and shear force. The major subjects studied in this paper were as follows, which were required to establish the design guideline of this structural type of beams: structural details for enhancement of structural and constructive performance; limitation of concrete strength and shear stress level; openings located at the boundary of un-bonded hinge isolated portion; and discussion of modeling of restoring force characteristics of beams with openings.
