About this detail

A hollow structural section steel column connects to hollow structural section steel beams using continuous plates at the top and bottom. A complete joint penetration weld connects the hollow structural section to the continuous plate, while the continuous plate matches the greater tube thickness plus one-eighth inch with fifty KSI steel. A five-sixteenth inch partial joint penetration or effective fillet weld secures the beam where the column extends, with fillet groove and flare bevel welds interchangeable depending on member geometry. Five-sixteenth inch fillet welds are applied on each side where geometry permits.
