In order to increase the ductility to the RC columns under high axial load, cyclic loading experiments of RC columns covered by steel tubes ware carried out. The RC columns covered by steel tubes were ductilitiful under 0.6 axial load ratio. The parameters (the hoop ratio, the strength of hoop and the thickness of steel tube) did not influence the maximum load, but influenced the ductility: increasing the cross-tie and the strength of cross-tie was more effective than increasing the thickness of steel tube, because the steel tubes did not yield, and the columns failed in flexural compression. Next, the result of this experiment and the results of other studies were examined. The flexural strength could be evaluated by the stress-block method considering the confined effect and corrected by the axial load ratio.
