Concrete Post Installed Anchor with Plate

Concrete Post Installed Anchor with Plate

Concrete Post Installed Anchor with Plate

(OP)
I have an application where I am expoxy bolting a plate to an existing concrete beam. On this plate I will be welding a shear tab to carry a beam reaction. Hilti provides a nice little program for the design of the expoxy anchors; however, I'm not so sure about how it is handling (if at all) checks on the plate being bolted to the wall. It appears that it may be treating the plate as rigid. Can anyone point me to some literature that discusses the design considerations of the plate being bolted to the beam? I know I shoud check for things such as shear tear out and the like, but I was more concerned with the proper assumptions of the compressive force distribution at the bottom of the plate. In the past, I have seen designs that assume a triangular distribution from the mid point of the plate. Any input would be appreciated. Thanks

RE: Concrete Post Installed Anchor with Plate

For the compressive force distribution, I would use the procedure for Column Base Plates with Moments outlined in AISC Design Guild Series #1.  Or, you could use the procedure shown for Column Bases in Blodgett's Design of Welded Strucures.

Thanks jmiec. I'll use the large eccentricity approach as described in Design Guide 1.
