Tension and shear force at top of foundation wall from braced frame
Tension and shear force at top of foundation wall from braced frame
(OP)
Hello,
I'm wondering how people typically deal with large tension and shear values at the top of a foundation wall from a braced frame. It appears that following Annex D Anchorage from CSA A23.3 concrete failure will occur unless I put a pilaster in the wall. I have read the Design of Anchor Reinforcement in Concrete Pedestals LINK and that method seems promising. Does anyone have any comments or typical methods to deal with these forces?

Thanks

I'm assuming the loads are actually significant? What about providing enough reinforcement and detailing accordingly that app D doesn't apply?

I wonder if there isn't some sort of sort of additional framing that could be done to transfer the shear and uplift at the base of the brace into a longer portion of wall or into the floor diaphragm (and subsequently into a longer portion of wall).

1) Use threaded rebar or deformed bar anchors instead of anchor bolts and position the bars in the center of the wall. This is pretty much the only way that I know of to deal with anchor side face blowout in an 8" wall. This should cover you for tension.
2) If shear capacity becomes and issue. Embed a steel plate with studs in the top of the wall on the brace side of the column and connect your brace gusset plate to 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.
