This paper presents a practical confinement system for columns using skew prestressed bars as transverse reinforcement, applied on axially loaded square cross sectional reinforced concrete columns. The sustain confines the concrete members to sustain larger loads and to improve the total behavior of the member into a more ductile one. The effect of skew prestressed bars on reinforced concrete column was investigated in five square reinforced concrete columns specimens divided into two groups. The first group consists of three specimens with transverse reinforcement Y8 spaced at 100mm,150mm and 200mm.The second group consists of two specimens with transverse prestressed reinforcement T20 spaced at 100mm and 200mm. All specimens had the dimensions of 200mm*200mm with total height of 1850mm and they were tested under concentric compression. Crack loads, crack pattern, curves of load and axial deformations for each specimen were recorded. The study showed that the strength and ductility of concrete columns are generally improved due to confinement using skew transversed prestressed bars.
