6.1 - Shear stud LAW (length after weld)

When installing shear studs, the length after weld should extend at least 35mm above the top of the main ribs in the deck profile. Therefore, the minimum stud height after weld should be 95mm for TR50, TR60+ and R51+ or 120mm for TR80+. The recommended minimum concrete cover to the top of the stud is 15mm, this should be increased to 20mm if the shear stud is to be protected against corrosion, as specified in BS5950-4.
