This structural steel detail shows a column framing perpendicular to a beam web with a bolted bearing plate connection. The assembly incorporates a three-quarter-inch bearing plate matching the column flange width and depth plus one inch, secured with four three-quarter-inch diameter bolts at the beam gauge. A column cap plate matches the bearing plate size above, while a base plate matches it below. A three-eighth-inch partial-height stiffener plate aligns with the column web and is welded with typical quarter-inch fillet welds on two sides.
