About this detail

A reinforced web penetration in a steel beam supports a composite metal deck slab. Plates designated PL #1 through PL #3 and doubler plate #4 are welded around the opening using specified weld sizes W1 through W4. Additional slab reinforcement consisting of number 4 bars at twelve inches spacing is provided centered over the opening. Shear studs are installed at two per foot minimum at composite slabs. For field-cut penetrations, all plates must be installed and welded prior to cutting the opening.
