A new reinforcement system, Prefabricated Cage System (PCS), is proposed to perform the function of longitudinal and transverse steel in reinforced concrete members. PCS is made from a solid steel tube or plate acting as transverse and longitudinal steel connected monolithically. PCS reinforcement eliminates some of the weaknesses and detailing problems inherent in traditional rebar reinforced concrete construction resulting in easier, more reliable, and faster construction. The confinement provided by PCS is investigated by comparing the results from 6 small-scale column tests. The specimens were tested by axially loading the concrete core. The effects of PCS tube thickness, and the width and height of transverse and longitudinal steel on the provided confinement and displacement capacity are investigated. Test results show that PCS provides higher confinement capacity than similar rebar reinforcement.
