Grouted rebar connection into existing masonry abutment

Grouted rebar connection into existing masonry abutment

(OP)
Hi all,

It's been proposed on a project I'm working on to land the base plate for a new steel structure onto an existing masonry abutment and connect in to the abutment by drilling into to the masonry, grouting in a dowel connection and the tensioning the bar after the base plate is installed on it's grout bed.

What I've done is work out the worst forces these anchorages will see and checked the bar for shear, tension and combined capacity. I've also checked the cone pull out mode in the masonry.

My question is, does anything else jump out that I should consider? Does anyone have a decent resource or example for this type of connection? I've found a few things but nothing that seems great.

Thanks in advance

Maybe a non answer but important: Include a test procedure as well. Easy if you will be tensioning anyway.
