This study investigated the seismic performance of external RC columns with concrete-filled steel tubes. Through the experiment, the behavior of strengthened column subjected to cyclic lateral load was evaluated. From the test results. the strength, ductility, energy dissipation and equivalent viscous damping ratio for seismic performance were determined and evaluated. The applicability to seismic performance prediction was verified by using the fiber model analysis and comparing it with the performance results from the experiment. As a result, the prediction of load-displacement curves were found to be quite similar to the test results.
