In SRC column, the closed hoops are applied with the same detail of both 135° standard hooks to expect the same performance as hoops of RC columns. This standard detail is actually complicated to construct, thus, two separating rebars are connected in the form of a square shape and welded over the overlapping section. But this is also complicated in construction practice. Therefore, this study describes experimental results regarding cyclic behaviors shown with alternative hoops cramped by the steel clip type-binding device instead of welding and standard specimen. As a result of the experiment, the specimens with alternative hoops of the SRC column showed comparable performance to the specimens with closed hoops. Therefore, it can be evaluated that the alternative hoops applied with the rebar confinement clips in the SRC column can replace the closed hoop.
