Flexural Behaviour of Prefabricated Cage reinforced Composite Beams

A member composed of two or more dissimilar materials joined together to act as a unit, in this a new reinforcement to be used to reinforced concrete members. This new reinforcement is patent pending and is developed and evaluated in this research. The proposed reinforcement, termed prefabricated Cage System (PCS), functions as both the longitudinal and transverse reinforcement connected and working compositely with the surrounding concrete to resist applied loads. Prefabricated cage reinforcement is fabricated by angle sections. The confinement provided by the prefabricated beams effectively improves the flexural strength and deformation characteristics of prefabricated cage. Various methods could be used to fabricate the cage reinforcement such as punching, cutting methods, welding and casting. Prefabricated cage reinforcement is prefabricated off-site and then placed .It can eliminating the time consuming and costly labor associated with cutting, bending, and tying steel bars in construction. Prefabricated cage reinforcement can be used to reinforce almost any kind of concrete member which involves reinforcement and concrete.
