Disclaimer: this connection can experience extremely high forces under design criteria, so it should be approved or designed by an engineer.

that being said:

Here is our most common pavilion post foot connection:

HDG allthread epoxied into the concrete. Drill the post foot for allthread and mortise into a non-show face to get in there and put a plate washer and nut on it. Plug mortise if it is in a show face. This connection is pretty good for uplift and some shear.

Size of allthread, plate washer, depth of embed, relish below mortise, and epoxy spec should be determined by your engineer.

Be sure to isolate the wood from the concrete. We usually use 1/2" thick black UHMW plastic.
