I am looking into the calculation of the brick breakout capacity and anchor pull out capacity calculated in Hilti Profis, the referenced technical guidance (ETAG 029 Annex C or TR054) do not seem to provide any equations or characteristic strengths (C.5.2.1.3 or C.5.2.1.4 in ETAG 029) needed to undertake these calculations.
E.g.: "C.5.2.1.4 Brick breakout failure
The characteristic resistances [are] ... given in the relevant approval."
Could you direct me to the 'relevant approval', be it an ETA, or alternatively does Hilts provide a manual of any kind?
Kind regards, James
Thank you for your question. You will find the latest ETA documentation online under the relevant product. I would suggest checking your local HILTI website to ensure you have the up to date information. You may also find online additional technical data that covers a wider range of masonry units outside of the ETA data.
