RE: ACI 318 Appendix D

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Instead of having the anchor rod /bolt head embedded inside the concrete member this rod is run from one side to the opposite side of the concrete member/footing and secured with an bearing plate and heavy hex nut.

I give up.  What do you mean by a through-bolt for this application?

 

 

thanks,

We also use through-bolts for fixing missing holdowns at shear wall ends.  Per Appendix D section 2.2 through bolts are not included.

In our office, we through-bolt all our concrete anchors and avoid Appendix D entirely.

 

One engineer in our office has a detail where he attaches the heads of his anchor bolts to chains which are in turn fastened to large chunks of Iron dropped in the bottom of the concrete pour, all to avoid Appendix D.

O.K., I've beaten my head against the wall long enough. I've decided that a post-installed anchor won't work in tension for anything I design.

 

I feel better now.
