In some applications it can be advantageous to arrange individual anchors in a group in slotted holes. If, for example, a fastening is loaded by a shear force in the direction of the edge of the component, the characteristic resistance for concrete edge failure is …
In December 2019, the Beton-Kalender 2020 was published by Ernst & Sohn. The yearbook contains a comprehensive essay on the design of fastenings according to the new European standard EN 1992-4.
EADs (European Assessment Documents) are the successor documents of ETAGs (European Technical Approval Guidelines). All published ETAGs will be converted into EADs…
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
