Adhesive Anchor design

[SKJ25POL]

So please correct or confirm my understanding in this reggards.
We can either use ASD or Strength Design (SD)-aci 318 for Anchor design?
Does Profis ASD checks all the checks done by Profis SD method?
Shall I expect same results?

Also, for Profis ASD, I put the ASD loads, Am I right to multiply ASD loads by 1.48 to get correct load input for Profis SD method?

Thank you for your direction. I am stuck here.

What is your governing building code?

IBC 2012 (and earlier) had ASD design provisions. IBC 2015 appears to have deleted those provisions.

Even in states governed by IBC 2012 and earlier the state building code may have removed the ASD provisions. Even if they still have the ASD provisions they couldn't be used with any earthquake loads.

The standard in the industry in the US is now LRFD.

Now that I read the above closer, you were asking about adhesive anchors which were never covered by the IBC provisions. LRFD has been the standard for adhesive anchors for quite a while.

 

[SKJ25POL]

The location of project is in US with 2012 IBC governing.
My question is not about what method legally is allowed to be used, my question is about if Profis Anchor, ASD method checks all the edge distance, pull out, break through, etc. as well as Profis Anchor SD method?

And if you have ASD loads and decide to use Profis Anchor SD method how would you convert the available ASD load into loads that can be plug for Profis Anchor Strength Method?

 

[Lomarandil]

If you know the ratio of the load components (dead, live, wind), just apply a load combination per usual.

If you don't know, and have room to be conservative, apply a load factor of 1.6 to everything.

Otherwise, you'll have to apply some further engineering judgement.

(Sorry, I can't help with your Profis specific questions)

 

[Guastavino]

SKJ, you can easily convert the loads using the load combinations in the structural chapter of the IBC 2012. I'd recommend just going ahead and doing that. ASD is going the way of the dinosaurs. It's a slow transition, but it keeps getting harder and harder to stay in the ASD world.

And ASD for adhesive anchors isn't allowed in the IBC 2012. IBC Section 1908 (ASD) says it doesn't apply to anchors installed in hardened concrete. For those it shoves you back to ACI 318-11 Appendix D which is only strength design.
