Four groups of specimens of damaged RC columns reinforced by winding steel wire were tested for axial compressions. One group was undamaged RC columns; the others were damaged RC columns, the width of crack developing was regarded as damage index, they were respectively 0.3mm, 1.0mm and 1.5mm, the helically-wound method was adopted for reinforcement, and winding spacing was 50mm. The testing results showed that under reinforcement the load of damaged columns improved a bit in comparison with undamaged ones, but with a little range, however, the strain of longitudinal reinforcement, stirrup and concrete could improve greatly, which indicated that it had a good effect to reinforce the damaged columns by winding steel wire, meanwhile, the ductility of damaged columns was improved apparently
