Anchor Design Software – Curious Design Results #4
If the number of tensioned anchors changes within an anchor group close to an edge due to variable loads, then there may be steps in the characteristic resistance for ‘Concrete cone failure’.
If the number of tensioned anchors changes within an anchor group close to an edge due to variable loads, then there may be steps in the characteristic resistance for ‘Concrete cone failure’.
When groups of mechanical or chemical anchors close to a component edge fail due to ‘Concrete cone failure’ then steps may occur in the characteristic resistance as soon as the axial spacing perpendicular to the edge exceeds the characteristic value…
Figure shows the characteristic resistance of a group consisting of four injection anchors M16 in a narrow component for the failure mode combined pull-out
The design of anchors in accordance with ETAG 001, Annex C or TR 029 may in certain cases lead to curious and illogical results that contradict the expectations of the users.
