Upon com- pleting his Ph.D., Dr. Cook joined the faculty at the University of Florida where he has conducted several research projects related to anchorage to concrete, primarily in the area of adhesive and grouted anchors. For deformed rebar, you don't need to do this as the force is transferred through friction between the rebar and concrete. For anchor bolt normally the anchor bolt holes on base plate Tension & Shear + ACI 318-08 Code, This example taken from Example 8 on page 71 of ACI 355.3R-11 Guide for Design of Anchorage to Concrete: Examples Using ACI 318 assure that the reinforcement steel yields before the concrete crushes.
