Transferring shear from column base to slab
Transferring shear from column base to slab
(OP)
I have a huge shear load (200k) at a TS6x6 braced frame column base that needs to transfer to the foundation. It's too much to take through anchor bolts into a spread footing. I'd like to transfer it to the slab on grade -- maybe thicken up the slab in this area. Any tips how to transfer the load? Maybe weld a channel perpendicular to the column just under top of slab?
Thanks.
Thanks.

If you can find the Design Guide #1, you'll be in good shape - they give worked examples. If you are an AISC member, it is free for download from their website.

Then only the shear from wind or seismic has to be transferred.

I think you would need some type of shear lug or key and transfer load directly to the footing in bearing. I would tie the two footings of the braced frame with a concrete grade beam. Provide dowels in the grade beam to transfer load to the slab on grade and then design your slab on grade to act as a diaphragm as you intended on doing.
