About this detail

A typical structural steel drag strut connection frames wide-flange beams into a 50 ksi steel column. A fifty ksi steel cap plate matches the greater beam flange thickness plus one-eighth inch and matches the greater width of the column or welded beam flange, connected with complete joint penetration welds to the column web. Wide-flange beams connect via shear plates featuring three seven-eighths inch erection bolts, or two bolts for W8 or W10 shapes, with plate thickness equal to the beam web thickness plus one-eighth inch. A three-quarter by six-and-one-eighth inch girder bearing plate rests beneath, supported by a one-half by five-inch by one-foot-zero-inch stiffener plate welded with five-sixteenth inch fillets on three sides. Welds are specified as five-sixteenth inch fillets on three sides, and three-eighths by five-sixteenth inch bevels at the column flange, with field welds designated for beams identified as SFRSC on plan.
