In most of the gable-steel-frame, column & beam have outer edge straight and inner edge slopping. Most of structure design software have tapered section property available for analysis and/or design. But, tapered section have both edges slopping.
I think it is not possible to get such frame members even with series of small line members connected and even if available we need to combine those small member to check slenderness, Lateral torsional buckling or elastic buckling and modification of forces due to such effects.
If such members are modeled with finite elements using ANSYS or other software, it will be difficult to check safety of design of such members.
If there any software where we can model, analyze and design such members truly?
