STRUCTURAL BEHAVIOR OF COMPOSITE REINFORCED CONCRETE DECKS WITH LIFE LINE STEEL TUBE SYSTEMS

Abstract

This study focuses on benefits to be gained by using composite beams with concrete slab attached to a circular steel tube alternative IPE section in steel beam. The experimental research program was attitude to evaluate the flexural behavior of these composite beams with circular steel tube. A total of fourteen beams divided into seven test groups with different variable, were fabricated and testing under static loading conditions to determine the ultimate load and mode of failure of composite beam with circular steel tube. It was found, that the proposed structural system proved the qualification in flexural behavior, this mean; it can be used in building and construction as structural member resisting the bending. In addition, this composite beam can be used to pass through it the service work as electrical lines, mechanical heating, ventilating, etc. without need to increase floor height and web opening making that was cause increase building cost. Also the new proposed section can be used to transport water or oil.
