Moment Splice of Beam
Moment Splice of Beam
(OP)
I am doing a retrofit of a structure that prevents a full length beam from being brought into the building. Therefore, the beam will need to have moment splice connections in one or more locations. I was looking to have the web plate connection as a bolted connection to assist in the erection process and the flange plates be welded. Is there any restriction per AISC that prevents the use of this type of bolted and welded connection at a moment splice? Everything that I have read only discusses welding all of the flange and web plates or bolting all of the web and flange plates. The beam will be installed under an existing composite deck; therefore, through bolting the top flange of the beam is not really an option so a fully bolted connection is not possible.

Personally I don't see a big problem, but if experience shows either all welded or all bolts designs then maybe there's something there. How would you bolt the web plates on ? before final placement ? You could use CSK bolts (not preferred, I understand) ?
Why bolt the web plates, in preference to welding them ?

Maybe using angles instead of straps (to get around the flange welds impacting the web welds) ?

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.
