Web shear design is accomplished by simply adding intermediate stiffeners between cross
frame locations until the displayed shear capacity graph exceeds the applied shear.
Shear stiffeners are displayed in yellow at the bottom of the graph with the cross
frames displayed as vertical dashed lines. Stiffeners can be specified at equal
spacing or at user specified distances.
The software performs a rigorous check of the web shear capacity at all critical
locations along the span including moment shear interaction.
