Flexural Behavior of Encased Beam Flat or Perforated steel Cold Formed Sections

다국어 초록 (Multilingual Abstract)

This paper presents an experimental study on the fl exural behavior of encased fl at cold formed steel sections FCFS and perforated cold formed steel sections PCFS. A full scale eleven specimens were prepared and tested till failure. One specimen without steel cold formed section tested as a control beam. Six specimens with fl at steel cold formed section were tested to fi gure out the enhancement eff ect of section area and position. Finally, four specimens with a new shape of perforated steel cold formed sections were tested with diff erent positions. Cold formed steel section height, fl ange width, and position are the main parameters studied and investigated. The ultimate load and vertical defl ections were recorded and investigated.
Also, modes of failure of the control and composite concrete beams were studied. From the experimental investigations, it has been observed that there is signifi cant increase in ultimate load of composite beams with a perforated steel cold formed section. A signifi cant increasing in the ultimate load was observed for specimens with perforated steel cold formed section
