In this study, structural tests were performed on the specimens that contained the de-bond of longitudinal rebars at the four corners of the RC beam with a guaranteed hinge position. Through this test, it was confirmed that the de-bond of longitudinal rebars at the four corners of the RC beam does not significantly affect the structural performance of the RC beam member, including the restoring force characteristic and energy dissipation capacity. Moreover, the cracks were concentrated on the hinge-side of the de-bond area, and the number of cracks in the de-bond area was suppressed.
