This study investigates the structural behavior and fire resistance of Shallow Steel-Beam-Concrete Composite (SSCC) decks, focusing on the influence of various Steel-Concrete (SC) bonding techniques. SSCC decks combine steel beams with concrete slabs, offering structural efficiency and durability under significant loads. The effectiveness of SC bonding methods is evaluated by comparing experimental results to Full Composite Action (FCA) simulations. Fire resistance in shallow floors, particularly SlimFlor systems, is analyzed using numerical simulations and parametric studies, highlighting their enhanced performance due to concrete’s thermal shielding of steel. Additionally, the paper explores innovative deck profiles, particularly a top-hat section with transverse corrugations, improving buckling and shear resistance. Experimental tests of various loading scenarios validate the performance of these profiles, which may prove effective in composite slim-floor systems. Design recommendations are based on Australian Standards, with a call for adjustments to accommodate these novel profiles.
