摘要：A method for strengthening an existing concrete column having a concrete body and a plurality of parallel longitudinal steel reinforcements includes the steps of preparing a steel wire cable that includes strands of steel filaments, winding the steel wire cable on the longitudinal steel reinforcements in a spiral manner relative to a centerline of the concrete body, fastening two opposite ends of the steel wire cable to the longitudinal steel reinforcements, and casting a structural material around the steel wire cable, the longitudinal steel reinforcements, and the concrete body.
