Concrete cone failure in accordance with ETAG 001 Annex C


We can now explain the principle of evaluation and determination of the required areas.

Concrete cone failure is evaluated in accordance with ETAG 001 Annex C.



The calculation of the areas A0c,N and A c,N takes into account the geometry of the concrete foundation (edge distance).



  1. A0c,N

A0c,N = 9 . hef2

  1. Ac,N

An area for each drawn anchor is determined (see picture below).


Subsequently, the union of the individual areas is created and is calculated one unified area Agc,N.

where n = number of tensioned anchors
