Abstract

Results of parametric studies on steel-deck-reinforced composite slabs with end anchorages provided by welded shear stud connectors are presented. The studies are based on the analytical model described in the companion paper. Effects of the number of studs, longitudinal shear strength, deck height, steel thickness, deck yield strength, concrete cover depth, concrete compressive strength, and deck span conditions on strength of the composite slabs and the stud strength mobilization were investigated. Simplified formulas for the determination of the minimum number of welded shear studs required to achieve the full moment of the section were developed. The formulas account for deck height, slab depth, concrete cover depth, steel thickness, steel yield strength, longitudinal shear strength, and slab span length, and predict the required number of studs with reasonable accuracy.
