Reinforced concrete columns are the critical members of moment-resisting structural systems and have to be designed adequately in strength and ductility. Transverse reinforcement in concrete columns plays an important role in the improvement of strength and ductility of columns, especially when they are subjected to severe ground motion. Transverse reinforcement in concrete columns can be used to delay the local buckling of longitudinal bars, resist shear forces, avoid the sudden shear failure and confine the concrete to improve the strength and ductility. The behavior of reinforced concrete members subjected to seismic loads is mainly based on the ultimate strength of concrete and its ductility. Reinforced concrete column models having different cross-section have been designed to investigate these parameters. The effects of the transverse reinforcement spacing and transverse reinforcement diameter on the behavior of column models have been analytically investigated. Previously proposed analytical models were used to investigate the behavior of the reinforced confined column models. Stress-strain relationships were obtained for the confined concrete columns and the obtained results were compared and interpreted.
