Flexural Performance of a Novel Steel Cold-Formed Beam–PSSDB Slab Composite System Filled with Concrete Material

In this study, the flexural performance of a new composite beam–slab system filled with concrete material was investigated, where mainly prepared from lightweight cold-formed steel sections beam and deck slab for carrying heavy floor loads as another concept conventional lower cost impact. For purpose, seven samples profile sheet–dry board (PSSDB/PDS) carried by C-purlins (CB) were named “composite CBPDS specimen”, which tested under static bending load. Specifically, effects sheet (PSS) direction (parallel or perpendicular to span specimen) using different configurations (double connected face-to-face, double separate sections, single section) investigated. The research discussed specimens’ failure modes, behavior, capacity, strain relationships, energy absorption index specimens. Generally, specimens PSS placed in parallel achieved approximately 13–40% higher capacity compared corresponding (depending on configuration beam). Fabricating specimen (face-to-face) led more effective confinement behavior beam. related recorded 10% capacity. Finally, suggested exhibited sufficient capability load because it demonstrated high strength ductility.
