embed plate design

I am looking for guidance on the design of steel embedment plates primarily subject to shear loads. In particular I am looking at a weld plate with anchor rods cast in a concrete column that supports a steel beam. I am unable to get the connection to work using Appendix D methodology. ACI 318 Appendix D seems to be overly conservative for calculating the capacity of the embedded anchors as it does not give significant credit for the reinforcement intersecting the failure plane.

I have had similar problems with concrete piers subject to shear and uplift loads.

Thanks in advance.
