EN 1993-1-8 Connection Design

FrameAI automatically classified the connections and verified component capacities per EN 1993-1-8 Β§6.2. All connections comply with the NA for NL (NEN 9990-1).

End-plate bending β€” T-stub model, row 1 (M20 10.9)
l_eff,cp = 144 mm, l_eff,nc = 176 mm, l_eff = 144 mm. M_Pl,Rd = 6.7 kNm per bolt row. 3 rows β†’ 20.1 kNm.
