A hollow structural section trellis frame constructed from HSS5x5 members connects to supporting steel framing using L4x4x3/8 angles on each side of the hollow structural section, welded with five-sixteenths inch fillet welds typical to both the angle-to-hollow structural section and angle-to-wide flange connections. A WT shape formed from a W12x40 supports a guardrail post with a sloped web to maintain a constant top of steel, tied together with three-eighths inch plates near-side and far-side at the hollow structural section location. A base connection anchors a hollow structural section column to a concrete wall per detail 4/S4-02 using a three-quarter inch by eight inch by one foot two inch base plate welded with quarter-inch and three-sixteenths inch near-side and far-side fillet welds, secured with two one-inch diameter by one-foot-zero-inch headed studs.
