Anchor Kwik Bolt 1

[kaffy]

Good Morning fellow engineers,
This is the first time I am working with Kwik Bolts(Anchor Bolts). I checked the allowable shear and allowable normal of the kwik bolt(Included edge and bolt spacing). What other Criteria do I need to check?
I was looking at one example where concrete and pull out was being checked as well. Also the data on Kwik bolts showing tha allowable shear and normal, is it for bolt failure/bolt coming out of concrete or concrete failure?

Thank You

Hilti has a free program, PROFIS, that does anchor bolt design. Playing with that can give you a feel for what needs to be checked and what bolts are applicable where

Is PROFIS still free? Last I checked I they wanted a license number to activate it. Coincidentally, I stopped specifying them...

It's web based now. You have to make a profile but the software is still free

phamENG,
I believe the "basic" module is still free (logged in this morning). You pay for the "Premium".

Not sure about that. But I did see that last time I recommended it to someone. We have it at the office and I don't recall ever receiving a bill for continued use. Maybe for legacy users it carried over?

kaffy: I mean, what you check for is dependent on your application. Are you designing for static or cyclic loads? Is there a particular load profile (short burst vs steady state)? What kind of concrete are you anchoring into (cracked vs uncracked, new vs old)? Tell us more about the application and we can tell you more about what might be worth considering. As it stands my answer is: everything one would check a bolt for (but if you give me more I can probably do better than that)!

Read ACI 318 Chapter 17 (or Appendix D if you have an older version). Also read the manufacturer's Evaluation Service Report...Google ESR 1917 for the Kwik Bolt TZ. Goes through all of the different capacity checks.

IIRC, this one only applies for uncracked concrete. You might want to use the Kwik Bolt TZ instead.

@271828: Kwik Bolt TZ is for seismic use. Kwik Bolt 3 is for cracked/uncracked non-seismic. From my understanding, they are the same bodies but TZ has more refined QA/QC and testing for seismic load.
