About this detail

An equal depth beam connection features Grade 50 plates that are one-half inch thick or match the beam web for thicker webs, secured with the maximum number of seven-eighths inch diameter ASTM A325 bolts. Complete joint penetration welds are specified with back-up bars removed, back gouged, and reweld with five-sixteenths inch fillet welds on all complete joint penetration welds. A shallow supported beam detail utilizes similar Grade 50 connection plates with three-quarter inch diameter ASTM A325 bolts and one-quarter inch fillet welds. All complete joint penetration flange welds are made typical across the assembly.
