These recommended standards need to be customized for small components and for heavily loaded members. The BCSA standards utilize a 50mm deep notch rather than the lowest notch depth specified in the property tables of steel section.In steel connection detailing process connections are assumed not to transmit any load from the target beam to another beam or column and for this to occur the connection must allow a small amount hot rolled steel coil of rotation.To reduce steel fabrication color steel sheet expenses, the BCSA (British Constructional Steelwork Association) has proposed a number of standardized angle web cleat, fin plate and end plate connections and you should follow this for building steel frames. All three of these are the most useful for steel beam/column or beam/beam connections.

With web cleats this happens from slip in the connected members and buckling of the cleats.To form beam-beam connections it is essential to notch the top and sometimes the bottom of the supported beam to clean up the flanges of the supporting beam. BCSA proposes use of fully threaded bolts or screws which are appropriate for 80-90% of connections in a typical steel frame.

Basic design routines used for steel connection detailing purposes are: flexible end plates, bolted angle cleats and fin plates. A standard bolt pitch of 70mm is applied wherever possible.When detailing steel beam connections or column connections you need to examine the CAD program output closely to make sure that the recommended design can be physically constructed and that there is sufficient room to tighten the bolts.
