Design and installation of construction fixings

Besides the assessment of the performance of construction fixings based on EADs and documented by ETAs, the design of the connection is the second pillar to guarantee reliable fixings.

Both, the intended use and performance of the selected fixing element and the design method shall take into account the base material and the load situation e. g.:

• static or dynamic load,
• cracked or uncracked concrete,
• single or redundant fixing or
• the expected service life of the fixing (50 up to 100 years).

General design rules are given in the Eurocode (EN 1992-4). Those rules are complemented by specific design rules for fixing products covered by EADs, which are defined in EOTA Technical Reports.

To enable reliable fixings, the installation of construction fixings shall strictly follow the design specification and the installation instructions of the manufacturer. Anchor installations shall be done by trained persons only.
