Shear Design

Notation

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

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:
