I) All parts are classified as non-slender<br />
β ≤ 39ε<br />
i<br />
The Shear check shall be verified using art. 6.2.6. Ref.[1]<br />
II) One or more parts are classified as slender<br />
β > 39ε<br />
i<br />
The Shear check shall be verified using art. 6.5.5. Ref.[1].<br />
For each part i the shear resistance VRd,i is calculated.<br />

ρu,HAZ Haz reduction factor of plate i<br />
α Angle of plate i to the Principal y-y axis<br />
Slender part<br />
Formula (6.88) Ref.[1] is used with properties calculated from the reduced shape for<br />
N+(ρu,HAZ) in the same way as for a non-slender part. => VRd,i,yield<br />
Formula (6.89) is used with a the member length or the distance between stiffeners<br />
(for I or U-sections)<br />
=> VRd,i,buckling<br />
=> For this slender part, the resulting VRd,i is taken as the minimum of VRd,i,yield and<br />
VRd,i,buckling<br />
For each part VRd,i is then determined.<br />
=> The VRd of the cross-section is then taken as the sum of the resistances VRd,i of all parts.<br />
