Web Panel Assignment

A web panel may consist of one element or more elements. Assign a Web Panel to the selected elements. This function is used to find the following results of the panel to check the buckling of web panels according to clause 7.4.3.4 of AS 5100.6: 2017.  

fl* : mean longitudinal in-plane stress on a cross section of the panel, but the algebraically higher of the two values on the opposites.
fb* : maximum longitudinal stress due to in-plane bending of the panel. The average values over the whole panel is used.
fv* : average design shear stress due to the applied shear force and, in a closed section, due to the applied torsional moment.
The average values over the whole panel is used.
