Anchor Bolt Design The Complex ACI Provisions ASDIP
2020 05 12 nbsp 0183 32 The design of anchor rods has become complex and cumbersome with the development of the ACI 318 anchoring provisions originally in the Appendix D of the ACI 318 11 and earlier and in the Chapter 17 of the ACI 318 14 and later This document covers the required steps in the process of the design of cast in anchor rods normally encountered in column
Design of Headed Anchor Bolts construccionenacero com
Note The bolt embedment depth shall be greater than or equal to Lj as given in Table IB for all bolt types The rationale for this basis is that the shear force Vi causes a bearing failure near the concrete surface and translates the shear load on the anchor bolt into an effective tension load by shear friction In the absence of tension load
