About this detail

This structural steel detail shows beam-to-girder connections configured for beams both greater than and less than two-thirds of the girder depth. The assembly connects a supported beam per plan to a supporting girder per plan, utilizing a plate thickness matching the beam web. Both top and bottom flanges of the beam are coped full-height with a full-height one-half-inch stiffener plate welded to the girder web. The connection incorporates two ASTM A325 slip-critical bolts and quarter-inch fillet welds securing the plate to the beam flange where required. Maximum bolt counts are provided based on beam dimensions, maintaining standard clearances and edge distances.
