About this detail

A braced frame connection at a column web condition uses end stiffener plates welded to the column flanges. The incoming wide-flange beam is trimmed when dimension x is greater than or equal to one-half inch, with a one-inch typical radius clip per the typical continuity plate clip detail. Stiffener plates require top and bottom thicknesses determined per Table A, ranging from beam flange thickness plus one-quarter inch up to plus one inch depending on the beam size. Connections must develop full capacity using either a two-sided fillet weld with each leg sized at five-eighths times the connecting plate thickness or a demand-critical complete joint penetration weld. Notes specify a three-inch minimum dimension and a two-and-one-half inch dimension at the weld toe.
