Shear Design

Notations

V_Ed = Design value of the shear force
V_c,Rd = Design shear resistance
S = The first moment of area about the centroidal axis of that pOltion of the cross-section between the point at which the shear is required and thc boundary of the cross-section
I = Second moment of area of the whole cross section
t = Thickness at the examined point
f_y = Yield strength
Y_MO = Partial factor for resistance of cross-sections whatever the class is
τ_Ed = Design shear stresses

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:
