The section shapes supported by the new design are:
Rolled Channels back to back
Rolled Channels toe to toe
Doubled rolled I sections
Doubled rolled I sections with plates
The scope of design of these compound sections includes both beams and columns and auto-design. For auto-design, the user can create their own section Order Lists for compound sections once they have added these to their database.
In general, the scope of strength checks undertaken is the same as for rolled sections with the following current limitations:
The design is for non-composite sections only.
Slender Sections are beyond scope.
High Shear case with minor axis moment is beyond scope.
Design of the lacing or battening system is beyond scope.
Only parallel flange sections can be used.
