About this detail

Proper fastening layout for metal decking and shear studs welded to supporting steel beams. Shear studs are centered on the beam and deck flutes, maintaining a minimum spacing of twelve inches on center for beams perpendicular to the deck flutes, and six inches on center for beams parallel to the deck flutes. When required stud counts exceed a single row, extra studs are placed in pairs or rows of three starting at each end of the beam with a maximum two-foot spacing. The metal deck is secured using Hilti ENPH2-21-L15 pins fastened to base metal per manufacturer evaluation reports. Full fusion welds are applied typically as noted.
