Abstract

The seismic performance of existing reinforced concrete (RC) elements to which seismic design was not applied is questionable. To evaluate the behavior of existing RC columns, column specimens with widely spaced transverse reinforcement and 90-degree hoop anchor hooks as variables were designed. Experimental tests were performed by applying a fixed low axial load and increasing lateral cyclic loads to the specimens. As a result, the hoop spacing and anchor hook angle did not significantly affect the load-displacement relationship and the dissipated energy before failure.
