Following customer requests, a number of steel compound sections can now be designed to the Indian design code. Such sections can be user-defined using the Compound section tool in Home > Materials > Sections > Manage Sections.
-
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.
