NEW: Beton-Kalender 2020
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.
Design of fastenings based on EN 1992-4
In addition to the design according to ETAG 001, Annex C, it is now possible to carry out design of mechanical and chemical fasteners based on the European standard EN 1992-4 in DesignFiX.
How to add your products in DesignFiX?
Create an Excel spreadsheet with all anchor families. Each anchor family may include different materials with multiple diameters. Anchor type: Sleeve type, bolt type, capsule system, injection system, material types, head types.
Anchor theory versus reinforced concrete theory
High-performance injection mortars are suitable for anchoring threaded rods and internally threaded sleeves as well as reinforcing bars.

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’.
EADs versus ETAGs
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…

Shear loads perpendicular to slotted holes
The European design guidelines for anchors (ETAG 001, Annex C for mechanical and ETAG 001, Technical Report TR 029 for chemical anchors) describe in section 4.2.2.1 the influence of slotted holes on the distribution of shear loads:
“Slotted holes in the direction of the shear load prevent anchors to take up shear loads. This can be favourable in case of fastenings close to an edge.”
