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 significantly increased if the anchors near the edge are positioned in slotted holes (Figure 1a). However, elongated holes can …
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.
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.
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.
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 (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
