ISO column cap with uplift, splice condition
ISO column cap with uplift, splice condition
(OP)
In designing a beam/column connection at a covered walkway, I end up with a net uplift on my 6x12 beam. The walkway is long, so they is no possibility of using a continuous beam the entire length- there will be a splice condition with two 6x12's abutting over a column.
Naturally, I want to spec a Simpson CCQ or a USP KCCQ, but both manufacturers have identical footnotes "uplift values do not apply to splice condition". Thanks a lot, manufacturers.
I could detail some ugly, multi-strap/bucket/clip connection, with everything interfering with one another, but surely, there's a connector out there, or some simpler solution. Ideas, anyone?

RE: ISO column cap with uplift, splice condition
Usually, it involves placing the bolts higher and more outward to achieve bolt end and edge clearances, per the NDS, to allow for the uplift to be resisted.
Of course this costs more, and probably won't make you any friends, but if visual expectations outweigh the cost impact then it's the way to go.
Otherwise you could use a standard CC cap and weld an inverted CC together to hold the beam ends down. However, a CC upright and inverted will leave a bit of space for a 6x12 beam to move up, this gap will need wood infill.
