Two distinct structural steel beam conditions supporting concrete slab depressions are detailed. The upper detail features a structural tee with a web thickness of one-quarter inch minimum, matching depth 'd' as indicated on the plan, welded to the top flange of a wide flange beam per plan with a one-quarter inch fillet weld at three inches on center typical and six inches at ends. The lower detail depicts an angle condition supporting a depressed slab, reinforced with two continuous number four rebars unless noted otherwise and number four rebars at twelve inches on center extending twenty-four inches each way, with a five-inch vertical drop.
