Strength, V: The required anchor reinforcement strength must be equal or larger than the anchor bolt steel strength,ΦVsa, if anchor design includes earthquake forces for structures assigned with Seismic Design Category is C,D,E, or F. (ACI Section D3.3) 2. Anchor Reinforcement Size: Size of steel rebar from #3 to #14. 3.
The concrete breakout strength limits the anchor design strength and make anchor bolt design not practical in many applications such as concrete pedestal, which has limited edge distances surrounding anchor bolts. In ACI 318-08 the definition for Anchor Reinforcement is introduced, and the strength of Anchor Reinforcement used to
The witnessed testing conducted by Simpson Strong-Tie was used to validate ACI 318-14, Chapter 17 design concepts for anchor reinforcement and the need to design the structural slab to meet amplified 17.2.3.4.3 (a) anchor forces for use in SDC C–F.

27/6/2019 · It seems that they are also basing their assumptions on a smooth reinforcing bar vs. typical deformed bars. I later also found a document/spreadsheet example on civil bay for anchor shear reinforcement design that appeared to be using the methods discussed in the paper and/or similar strut and tie method to design the ties.
Design of Anchorage-Zone Reinforcement in Prestressed Concrete Beams by Peter Gergely and Mete A. Sozen NOTATION The symbols as used in the text are defined as follows: p — uniform stress on cross sec-tion due to prestress c — distance to the longitudinal crack from the bottom of beam e — distance to the applied force from the bottom of beam
Anchor Reinforcement: For cast-in-place anchors, PROFIS Engineering allows the user to select anchor reinforcement in tension and/or shear to prevent concrete breakout, thus stating that the concrete breakout utilization is 0%. This feature will not be available for post-installed anchors due to the complexity of trying to properly place the ...

Effective Area of Anchor Bolts. For both design methods, the anchor bolt net area used to determine the design values presented in this TEK are taken equal to the following, which account for the reduction in area due to the presence of the anchor threading: ½ in. anchor = 0.142 in.² (91.6 mm²) ⅝ in. anchor = 0.226 in.² (145.8 mm²)
18/5/2010 · One of the major additions incorporated in Appendix D of ACI 318-08 is the definition of anchor reinforcement in addition to the previously defined supplementary reinforcement. However, ACI 318-08 does not provide the specific guidelines for designing such reinforcement. This paper presents methods for designing a typical anchorage in reinforced concrete …
The magnitude of an anchor load is governed by either: (1) the tensile capacity of the steel bar or multi-strand cable; or, (2) the pull-out resistance of the bond between the grout and surrounding soil. In some cases, design of anchor systems rely …
