Abstract
Abstract
This paper presents experimental results of combined cyclic load testing on a reinforced concrete (RC) column that was retrofitted with newly designed steel rods. The steel rods were installed around the column longitudinally and then anchored. The proposed steel rods utilize simple components and installation to enhance both the strength and ductility of RC columns. One column was tested as a reference specimen, while two were tested after retrofitting using steel rods. All specimens were tested under eccentric constant axial load and incrementally increasing lateral loading cycles with eccentricity. The test parameters include the retrofitting length, a specimen that was retrofitted to the entire length of the column, and a specimen that was retrofitted to the plastic hinge length. The implementation of steel rods resulted in significant improvement in ductility and an up to 60% increase in ultimate loading capacity.
