Notation
Wel, min = Minimum elastic section modulus
Weff, min = Minimum effective section modulus
Wpl = Plastic section modulus
MEd = Design bending moment
Mc, Rd = Design resistance for bending about one principal axis of a cross-section
fy = Yield strength
YMO = partial factor for resistance of cross-sections whatever the class is
YMI = partial factor for resistance of members to instability assessed by member checks
YM2 = partial factor for resistance of cross-sections in tension to fracture
6.2.6 Shear
Design of shear should satisfy Eq. 6.17.
For class 1 and 2:
Av, shear area, is taken into account as follows:
For I and H sections:
for channel sections:
For class 3 and 4:
