Abstract
The National Institute of Standards and Technology recently expanded its large-scale structural-fire testing capabilities in the National Fire Research Laboratory. A landmark test series is being conducted on long-span steel-concrete composite floor beams designed and constructed following U.S. building codes and standards. The test program consists of five 13 m span composite beams with one of two types of shear connections: bolted/welded double-angle connections or single plate shear connections. Two of the five specimens have slab continuity at the beam ends. This paper presents the results from a recent test on the composite beam conducted at ambient temperature. The experimentally measured behavior and flexural moment capacity will be used as a baseline to compare with the composite beams still to be tested under combined mechanical and fire load. The datasets produced are providing technical information necessary to advance performance-based design of composite floor systems in steel- framed buildings subject to fire.Proceedings Title
