Notations

W_{el, min} = Minimum elastic section modulus
W_{eff, min} = Minimum effective section modulus
W_pl = Plastic section modulus
M_Ed = Design bending moment
M_c, _Rd = Design resistance for bending about one principal axis of a cross-section
f_y = Yield strength
Y_MO = partial factor for resistance of cross-sections whatever the class is
Y_MI = partial factor for resistance of members to instability assessed by member checks
Y_M2 = partial factor for resistance of cross-sections in tension to fracture

Bending Member Definition

These are elements that are under the effect of a simple flexural moment around their principal axes. For the elements that are under the effect of the simple flexural moment, the loads should be acting in the plane parallel to the principal axis passing through the shear center or the element should be supported against torsion at the load application points and supports.

6.2.5 Bending moment

Design of bending elements is determined according to Eq. 6.12.

• Bending strength is determined according to Eq. 6.13, 6.14 and 6.15.
