The purposes of this study are 1) to evaluate the applicability of 3.5 in. and 4 in. deep trapezoidal and dovetail decks for use with composite beams and 2) to develop a novel shear test setup for headed shear studs. The new shear test setup was designed to address limitations of the traditional push-out test by eliminating undesirable limit states, more accurately capturing post-peak slip, and reducing bias in data by having only one slab. The study includes 93 tests with 31 unique combinations of steel deck, stud layout, and concrete properties that cover approximately 90% of practical design space. The results will be compared to current AISC equations and used to evaluate the strength of shear studs in composite steel beams with concrete-filled steel decks that have decks deeper than currently allowed. Further validation will be conducted through full-scale composite beam tests.
