Design of Anchor Reinforcement in Concrete Pedestals

Even though the Appendix D of the ACI 318-05 permits the use of supplementary reinforcement to restrain concrete breakout, it does not provide specific guidelines in designing such reinforcement. This paper presents a method for designing anchor reinforcement in concrete pedestals, where un-reinforced concrete is insufficient to resist anchor forces. Anchor reinforcement consists of longitudinal rebar and ties to carry anchor tension forces and shear forces, respectively. The Strut-and-Tie Model is proposed to analyze shear force transfer from anchors to pedestal and to design the required amount of shear reinforcement. A proposed design procedure is illustrated in an example problem.

do you have sample problems with L or J type anchor bolts? What about using CM 66 instead of using ACI 318 Appendix D?
