The critical cross-section is verified for bending moment in accordance with EN1993-1-1 §6.2.5:
MEd / Mc,Rd ≤ 1.0
- For class 1 or 2 cross-sections the design resistance Mc,Rd for bending about one principal axis is estimated as the corresponding plastic bending resistance Mpl,Rd on the basis of the corresponding plastic section modulus Wpl:
- For the major axis y-y: Mc,y,Rd = Wpl,y ⋅ fy / γM0 = kNm
- For the minor axis z-z: Mc,z,Rd = Wpl,z ⋅ fy / γM0 = kNm
- For bending about the major axis y-y utilisation:
