About this detail

Headed shear studs welded through metal deck perpendicular to a supporting steel beam follow a specific layout and spacing procedure. Headed studs in a single row must be placed directly over the beam web, with up to three studs permitted per individual metal deck rib. When deck spans perpendicular to the support, studs are placed in alternating flutes for the entire length of the beam before adding second and third studs equally spaced from each end toward the center. The layout maintains a minimum 1 1/4 inch bottom dimple in the deck rib and locates studs adjacent to the dimple while considering the ceramic ferrule. Additional rules govern multi-line spacing for flange widths less than 6 inches and require shop drawings showing stud placement per specifications.

HEADED STUDS IN ONE ROW SHALL BE PLACED DIRECTLY OVER THE BEAM WEB. 3. PLACE STUDS IN A SINGLE ROW WHERE SPACING REQUIREMENTS PERMIT. STUDS SHALL BE PLACED IN TWO ROWS OR THREE ROWS ONLY WHERE REQUIRED IN ORDER TO PLACE THE TOTAL NUMBER OF STUDS. 4. MAXIMUM NUMBER OF STUDS PERMITTED PER INDIVIDUAL METAL DECK RIB IS 3. 5. STUD PLACEMENT PROCEDURE FOR DECK PERPENDICULAR TO SUPPORT: PLACE A STUD IN ALTERNATING FLUTES FOR ENTIRE LENGTH OF BEAM. PLACE REMAINING STUDS IN FLUTES WITHOUT STUDS, STARTING AT THE ENDS OF THE BEAM AND CONTINUING TO BEAM CENTER. DISTRIBUTE HEADED STUDS EQUALLY FROM EACH END. IF STUDS REMAIN, PLACE A SECOND STUD IN EACH FLUTE, EQUALLY SPACED FROM EACH END TOWARD CENTER OF BEAM. IF STUDS REMAIN, PLACE A THIRD STUD IN EACH FLUTE, EQUALLY SPACED FROM EACH END TOWARD CENTER OF BEAM. 6. USE WHERE MULTIPLE LINE SPACING IS REQUIRED AT A FLANGE WIDTH LESS THAN 6". 7.
