Thomas Holland-Letz and Ulrich Bourgund, from the Construction Fixing Europe Association, focus on the reliable design of fastenings based on ETAs, EN 1992-4 and EOTA Technical Reports.

Sound and reliable fastening solutions with anchors require proper performance data of the respective product and a suitable design methodology  in order to ensure the appropriate level of safety (Figure One). Over recent years product performance data based on ETAs and design in accordance with  Eurocode 2 , Part 4 (EN 1992-4) has been widely accepted in the engineering community for this purpose.
