Tension capacity of Anchor bolts at Wood Frame Construction
Tension capacity of Anchor bolts at Wood Frame Construction
(OP)
I am trying to find out the pull-out (tension) capacity of 1/2" dia. anchor bolt w/ 12" embedment into the concrete (I have 2x6 cont. P.T. sill plate over concrete basement wall). Where can I find this information? Does NDS manual has this information? I could not find it in NDS though. I would appreciate your help on this.
FYI: This is wood frame construction. I am designing a house for overturning.

I would rotohammer and epoxy in a separate A36 all-thread anchor though, relying more on what I know than what I don't know.
Hopefully you intend to anchor directly to the bolt and not put the sill plate in cross grain bending...

Thanks for the prompt response. For more info, the anchor bolts will be installed while pouring concrete for basement wall (8" thick). This is not post installed case. And the sill plate is on the top of the wall.
I am not sure your answer does apply in my case.
RE: Tension capacity of Anchor bolts at Wood Frame Construction
There have been some very questionable prescriptive requirements that could cause mush closer spacing than you would think. They were changed because of one type of foundation, but apply to all foundation anchor bolts. Some jurisdictions have eliminated that portion of the code until the newer version is released.

Other than trying to save hardware and money, is there another reason you have not mentioned why you do not want to use a standard holddown?
