About this detail

A structural steel beam frames into a hollow structural section or wide-flange steel column using a steel cap plate and shear plate. The steel beam connects to the steel column via a shear plate welded to the beam web with a five-sixteenths inch fillet weld on three sides and fastened with three seven-eighths inch diameter erection bolts, reduced to two bolts for W8 or W10 shapes. The top flange of the steel beam connects to a fifty KSI steel cap plate using a complete joint penetration weld with a standard weld access hole. The cap plate thickness equals the greater beam flange thickness plus one-eighth inch, and the shear plate thickness equals the beam web thickness plus one-eighth inch. Bevel cuts of three-eighths and five-sixteenths inch are specified at the column flange junction. A bolted top flange collector connection alternative is available upon contractor request during bidding.
