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.
High-performance injection mortars are suitable for anchoring threaded rods and internally threaded sleeves as well as reinforcing bars.
