About this detail

A structural steel beam frames into a steel column adjacent to a concrete tilt-up wall panel, functioning as a drag strut. An embed plate measuring one-half inch by twelve inches by one foot two inches is cast into the concrete wall and anchored with four three-quarter-inch diameter by five-inch head stud anchors at nine inches gauge at each column, split in half when occurring at a joint. A steel cap plate sized per the column schedule sits atop the steel column and is welded with a three-sixteenths-inch fillet weld on three sides typically. A three-inch by three-inch by one-quarter-inch angle, eight inches long, connects the column cap plate to the wall embed. The steel beam connects to the column using a bolted shear tab welded with a seven-sixteenths-inch fillet weld on three sides typically at beams designated as spray-applied fire-resistive construction on plan. Reveals or recesses in the concrete tilt-up panel are coordinated with architectural plans to a maximum of three-quarters of an inch.
