These structural details show heavy built-up steel beam connections utilizing bolted shear plates and high-strength bolts. The first two details illustrate built-up steel beams framing into supporting members at Level 14 and Level 7, featuring groups of one-inch diameter A490-X bolts through web plates of varying dimensions such as PL1-5/8x18 and PL1-7/16x19-1/2. Fillet welds of seven-sixteenths or one-eighth inch tie the connection plates to the webs. The third detail indicates specific beam coping requirements, directing top and bottom flanges to be coped and stopped one-half inch before the connecting member with a three-eighths inch fillet weld or one-half inch alternate weld specified for skewed beam connections.
