Classes of Anchor Bolts in RF-/JOINTS Steel - Column Base
Tips & Tricks
Table 3.1 of EN 1993‑1‑8:2010‑12 defines the nominal values of the yield strength and the ultimate limit strength of bolts. The bolt classes given here are 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 10.9. The note for this table states that the National Annex may exclude certain bolt classes. For the NA of Germany, these are the bolt classes 4.8, 5.8, and 6.8.
This regulation is implemented in RF‑/JOINTS Steel - Column Base. The selection of the bolt classes in the 1.6 Anchor window is dynamically adjusted depending on the chosen National Annex.
