Concrete anchorage under wall element
Concrete anchorage under wall element
(OP)
I have had some conversations about a concrete anchorage breakout with another engineer. The issue is (for example) you have anchorage into large footing or other large concrete mass and you have a solid concrete wall that sits on the projected failure area, how does it affect your breakout calculation. I am more inclined to ignore it myself but this has come up between us more than just a few times. I would love to hear some thoughts/references on the matter. Thank you.






RE: Concrete anchorage under wall element
The common situation that gets me wondering is base plates with moment and deeply embedded anchors. I suspect that a concrete strut connects the anchor head and the compression block under the baseplate such that tension breakout isn't nearly as bad as it would at first seem.
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.
