Study on the behaviour of prefabricated cage reinforced concrete beams

Abstract

Construction time plays a vital role as it affects the life cycle cost of the project In reinforced concrete system time consumed to cut bend and tie the reinforcement bar is more Moreover in heavily reinforced sections it may be extremely difficult to assemble the reinforcement bars During construction of structures and bridges with very heavy traffic project completion time is more important The Prefabricated Cage eliminates these difficulties and can play a vital role in fast track construction against the time consuming conventional process The Prefabricated Cages are produced by cutting out uniform rectangular openings on a cold formed steel sheet or tube The vertical continuous strips perform the function of stirrups while the horizontal strips act as main longitudinal reinforcement Since these cages are fabricated in industries using CNC cutting better quality control can be maintained
