An improved reinforced method used for concrete columns strengthened with angle steel and self-compacting concrete is proposed. Static loading experiments for sixteen specimens were carried out to study the infl uences of angle steels and batten plates spacing on axial compression bearing capacity of the concrete columns reinforced by the proposed method. The results show that axial compression bearing capacity increases signifi cantly; angle steels and concrete column can be eff ectively united to resist the loads from superstructure because of self-compacting concrete; the increase of area of angle steel and the decrease of batten plates spacing can eff ectively increase axial compression bearing capacity of the reinforced columns.
