About this detail

A steel beam connects to a steel column using a welded shear plate and continuity stiffener plates at the top and bottom flanges. The shear plate is welded to the column web and stiffener plate on three sides and features three seven-eighths inch diameter erection bolts connecting to the steel beam web, reduced to two bolts for W8 or W10 profiles. Plate thickness equals the beam web thickness plus one-eighth inch, and stiffener plates match the greater beam flange thickness plus one-eighth inch with a minimum fifty KSI yield strength. A complete joint penetration weld secures the beam flange to the stiffener plate, supplemented by five-sixteenths inch fillet welds at the stiffener plate to column flange and column web connections. Standard weld access holes are provided at the beam web, maintaining a minimum one inch depth and two-thirds beam depth clearance.
