About this detail

Incoming beams frame into a supporting member with concrete on steel deck above. A typical Type C1 connection plate is bolted to the beam web with three bolts. Grade 50 stiffener plates, measuring one-half inch thick with widths matching the beam flanges, are welded to the supporting member using complete joint penetration welds at the top and bottom flanges and seven-sixteenth inch fillet welds. Additional one-quarter inch fillet welds secure the stiffener plates on three sides as specified. The supporting beam is sized per plan, and dimension X is maintained at less than twelve inches.
