Performance of Concrete Filled in Cold Form Steel Sheet with Shear Connector under Pure Bending

Abstract

This paper investigates Performance of concrete filled in cold form steel sheet with shear connector under pure bending. A model is created using <span style="mso-bidi-font-weight: bold;mso-bidi-font-style:italic">ABAQUS to predict the performance of concrete filled in cold form steel sheet with shear connector to find moment carrying capacity ultimate point. The concrete filled in cold form steel sheet<span style="mso-bidi-font-weight:bold; mso-bidi-font-style:italic"> beam investigated and compared by finite element programme ABAQUS against experimental and theoretical data<span style="mso-bidi-font-weight:bold; mso-bidi-font-style:italic">. The reinforced concrete beam shuttered with the cold formed steel sheet and stud T shaped shear connectors were welded on three sides of the beam. Bracings were provided on the top of the beam in the pure bending region. The moment capacity depends on the parameter of q, which is ratio of force in shear connectors and force in bottom reinforcement. The experiment was carried out with various spacing of shear such as 75,100,125 and 150mm, we found that beams of 75mm spacing of shear connector takes higher ultimate load. The comparison of ultimate bending moment vs. spacing of shear connector for the beams analyzed with experimental, theoretical and ABAQUS value gives 75 mm spacing attain the good ultimate strength of the beam.
