About this detail

A steel beam to steel column collector connection within a special force-resisting system. Steel beams frame into the steel column web utilizing a shear plate connected with three seven-eighths-inch diameter erection bolts, reduced to two bolts for W8 or W10 framing members. The shear plate thickness equals the beam web thickness plus one-eighth inch, welded to the beam web with five-sixteenths-inch fillet welds on three sides and to the column web and stiffener plates with five-sixteenths-inch fillet welds. Top and bottom beam flanges are connected to horizontal stiffener plates using complete joint penetration welds, with the stiffener plate thickness sized to the greater beam flange thickness plus one-eighth inch using 50 KSI steel. Stiffener plates are welded to the column flange with five-sixteenths-inch fillet welds, and upper and lower stiffener plates are welded to the column web. A weld access hole is provided at the beam web, and a concrete slab over metal floor deck bears atop the assembly.
