Shear<br />
The design value of the shear force VEd at each cross-section shall satisfy (Ref.[1]):<br />

Where VRd is the design shear resistance of the cross-section.<br />
• Slender and non-slender sections<br />

<strong>Scaffolding</strong><br />
The formulas to be used in the shear check are dependent on the slenderness of the cross-section<br />
parts.<br />
For each part i the slenderness β is calculated as follows:<br />
⎛ h ⎞ w ⎛ xend<br />
− x<br />
β i = ⎜ = ⎜<br />
t ⎟<br />
⎝ w ⎠ ⎝ t<br />

⎠<br />
i<br />
With: xend End position of plate i .<br />
xbeg Begin position of plate i.<br />
t Thickness of plate i.<br />
For each part i the slenderness β is then compared to the limit 39ε<br />
