About this detail

A continuous hollow structural section framing connection at the roof level is positioned adjacent to a stud wall and curtain wall interface. The assembly incorporates a continuous hollow structural section sized per plan, with top of steel aligned at thirty-five feet and zero inches. A five-sixteenths by three-inch plate is welded to each side of the hollow structural section using five-sixteenths fillet welds, paired with five-sixteenths plates matching the width of the structural section plus two inches. Perimeter and backspan beams connect via fillet welds of one-quarter and five-sixteenths inch sizes. Field welds are executed at the contractor's option, with concrete fill on the metal deck required prior to hollow structural section installation.
