Embedded steel plate in concrete 2

[Alvarobg]

Hello every body!
I am designing an steel anchorage and I have one doubt. I have a bolt postensioned, which has not contact with concrete. It is joinned with a steel plate which is embedded in concrete. When calculating the steel plate: Can I consider that the embedment improve the strength of the plate? or I have to consider uniquely the plate thickness?
PD.: attached sketch.
Thank you

You'll need to design the steel plate thickness for the applied concrete bearing stresses show in your right hand sketch.

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.

I assume uniform loading over the plate area, and then design the plate for that loading as though the concrete were not there. That is, I don't assume the plate is stiffened in any way by the concrete. This will usually lead to small thick plates.

Thank you for the answers. Yes, designing the plate as though the concrete were not there is the practical way, but I need to reduce a little the thickness of the plate...

It's not just the practical way, it's the right way. Unless you're willing to FEM model the whole assembly, I don't see how you could quantify what little benefit the surrounding concrete might offer in this case.

I can't see the plate thickness being reduced significantly anyway. It's not like you'd be able to go from 2" thick to 1/2". So why bother with the advanced analysis.
