Common anchor bolt configurations include a rod that is threaded on both ends with a nut and/or anchor plate welded to the embedded end of the anchor bolt. Headed anchor bolts can also have an anchor plate welded to the head of the bolt if the head itself does not provide enough pull-out resistance.

Be careful with this. Engineers often use rebar in place of anchor bolts because they think that it's a workaround for Appendix D. For the most part, it's not. The only major failure mode that rebar addresses is side face blow out. Other than that, it's just an anchor bolt. In fact, it's an anchor bolt that actually develops more slowly than a common rod with nuts or an anchor plate. If you can manage to get your pier rebar to lap directly with your rebar anchor bolts, then you can skip the anchorage voodoo. That's pretty rare though. The greatest trick that bond stress ever pulled was convincing the world it didn't exist.I got so focussed on the warning that I forgot to actually try to help. If you go with rebar anchor bolts. I'd recommend looking at it as a strut and tie joint. The end result will be long-ish rebar-bolts and some concentrated ties at the top of the drilled piers. Essentially a well thought out non-contact lap splice. The greatest trick that bond stress ever pulled was convincing the world it didn't exist.I don't see how you would breakout the concrete in tension; the rebar is developed fully into the drilled pier and is pretty close to the drilled pier rebar cage. As long as cover and development length requirements are met, you won't breakout the concrete in tension.That's the classic misunderstanding smvk3 assuming that embedding the rebar Ld means that you've achieved anchorage to the concrete. You've only got anchorage to the pier in this scenario if 1) You effectively lap the bolts with the pier cage as I've described above or; 2) You make the Appendix D style anchorage checks work (they won't). The greatest trick that bond stress ever pulled was convincing the world it didn't exist.I have often used reinforcing steel for anchor bolts, but never had to deal with "Appendix D". When using threaded deformed bars, be careful of the force used, as the outer skin which is removed in threading is the strongest part of the [email protected] 1) You didn't use app D but you did take measures to effectively lap the bolts and the pier verts, right? And that required more than Ld? Before strut and tie, we would speak of a 35 to 45 degree failure surface with bars lapped on both sides of it. Sometimes, we still do. 2) I wasn't aware of the higher strength material lost at the outer surface of the rebar. How do we account for that? The greatest trick that bond stress ever pulled was convincing the world it didn't exist.1) Yes, appropriate measures are taken in the detailing, depending on the loads involved. 2) See the last page of the attached. reinforcing.au/~/media/OneSteel%20R...I don't see how you need to lap the rebar with the drilled pier rebar cage; if you develop the rebar into the drilled pier, the load will be transferred into the drilled pier through the friction between the rebar and the concrete. What you are talking about is the method ACI appendix D uses (which they call "anchor reinforcement") where you have to lap an anchor bolt according to a a 35 degree tensile failure cone. For deformed rebar, you don't need to do this as the force is transferred through friction between the rebar and concrete. The design tensile strength of the rebar (LRFD)would be 0.75*(Ane)(Fy) where Ane is the net area of the rebar (which takes into account the area removed from the threads).For shear transfer, I use the ACI shear friction method with a coefficient of friction of 0.7, and a rebar area of Ane, where Ane is the net area of the rebar (which takes into account the area removed from the threads)[email protected] I strongly disagree with your 23:31 post. Consider this extreme situation Link . If simple anchor bolt/rebar development length got the job done, it would be fine. Clearly, however, it's not fine. The remedy is to run the vertical cage up so that the bars can be effectively lapped, as mentioned previously. Your question about the use of shear friction here is an interesting one. I'm curious to see what others have to say about that. I don't know the answer. Quote (smvk3) What you are talking about is the method ACI appendix D uses (which they call "anchor reinforcement") where you have to lap an anchor bolt according to a a 35 degree tensile failure cone. Not so. This is a long standing rational method that predates appendix D. See AISC design guide number one. The greatest trick that bond stress ever pulled was convincing the world it didn't exist.
