In my engineering firm we developed a set of connection standards to address a variety of steel framing conditions. I published this and repeatedly cleaned up any RFI’s that were generated. This is an example of “LEAN improvement” to an engineering process. About 90% of typical commercial building connections are covered, both welded and bolted connections.
This second sheet is a continuation from the first sheet. These two sheets work together on a project. The connection types are developed from the flow chart to ensure that the design intent is met. A full-depth single-angle connection is the philosophical starting point to simplify the number of beam types for a typical project. Using 7/8″ diameter bolts, full depth, generally matches capacity for a 100 psf floor live loading with about 50 psf dead loading. Great for commercial work. For residential projects, you can use 3/4″ bolts.
