About this detail

A steel framing connection at an exterior building popout integrates concrete and steel members. The assembly includes a 3/4-inch end plate, a 1-inch seat plate, and two 3/4-inch erection bolts per joist manufacturer specifications. An embedded plate secured by three 3/4-inch threaded rods welded all around with a 1/4-inch weld anchors the connection to the concrete wall. Additional steel plates measuring 3/4 x 9 1/4 x 34 inches, 1/2 x 7 1/2 x 34 inches, 1/2 x 15 x 34 inches, and 3/4 x 13 x 19 inches provide stiffening and bearing support. An infill blockout with concrete or non-shrink grout fills the recess around the structural members, and fillet welds are specified at various locations including 1/4-inch and 5/16-inch sizes on three sides.
