Two distinct structural steel connection configurations compare a bolted-and-welded assembly with a bolted-only assembly. The first section utilizes double angles such as 2L4x4 with specified welds to the supported member governed by notes, alongside bolts matching in number and size per row. The second section applies a bolted-only connection using double angles like 2L5x5 with a minimum one-and-a-half-inch edge distance. Bolt edge distances and spacing requirements vary based on fastener grade, requiring five-eighths inch for Grade A325 bolts and seven-eighths inch for Grade A490 bolts.
