thread507-314031: Headed Anchor Rod Confinement Steel per ACI
Hello, appreciate with all the information shared within this thread.
From "Design of Anchor Reinforcement in Concrete Pedestal", to be considered effective resisting anchor tension, distance from anchor head to the reinforcement shall not be more than hef/3. From civilbay reference, this distance shall not be more than 8" (200mm). However, from ACI318-11, the figure shown for Clause D5.2.9, the figure was stating this distance shall not more than hef/2. The code does not explain any further.
Please, if anyone can guide me through which of these limitation should be valid and where they were referred from? Many thanks

The 318 Appendix D approach is to have one hairpin located adjacent to each stud or set of studs.
RE: ACI 318-11 D.5.2.9 Effective rebars tensile resisting distance
If hef = 1000mm, so all rebars within 500mm (hef/2) radius can be taken into account as anchor reinforcement. But these rebars will be at a distance < 6" (150mm) as per 12.14.2.3 ...hence we shall provide hairpins as a medium in between anchor and rebars in order to make anchor reinforcement to effective?
