Structural performance of rectangular concrete section confined by squared spirals was investigated. Through the uni-axial compression test using concrete prisms with squared spirals and without longitudinal bars, the enhancement of strength and deformation capacity of rectangular concrete section was scrutinized. By the experimental observations on the properties of lateral expansion of concrete prism, a moment of reaching the axial peak stress in section was predicted in a good accuracy. Qualitative relationships between the structural performance (the enhancement of strength and deformation capacity) of concrete prism and confinement efficiency were studied. Also, for the effective use of normal- and high-strength lateral reinforcement, a design implication using the qualitative relationship of the tensile stress in lateral reinforcement at failure of concrete prism with parameters was proposed.
