Beam-to-beam connection.

Beam-to-beam connection.

RE: Beam-to-beam connection.

It would need to be slip critical if it is subject to significant load reversal or fatigue loading.

RE: Beam-to-beam connection.

Other than for specific applications, such as those that Mike mentioned, why would you want to design the connections as slip critical? Slip critical has more expensive surface prep and inspection requirements.

That said, if you really do want slip critical connections, I see no problem with that.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

RE: Beam-to-beam connection.

(OP)
Hi, and thanks for the responses.

Both beams will be carrying heavy brick walls going up two floors under separate ownership. The building is 1870s and the brickwork is not well-bonded. Once the main beam is in, I was concerned that if the secondary was supported off ordinary bolts in clearance holes, that end will drop very slightly once the props are out, and may cause cracking in the corner above.

I know it will put a moment into the main beam, but apart from that all I seem to read is that it shouldn't be done (except as mentioned above for cyclical loading).

RE: Beam-to-beam connection.

Ah.. I see. I see no reason why that would't work. It would probably be much more constructable with slotted holes as well.
