cold formed built up closed section

[MonsieurR]

Hello everyone

I'm trying to recopilate information useful for design relating cold-formed built up closed section, for example the attached or similar types.

I'm looking for resources similar or maybe a bit more practical than AISI guides, yet a bit more complete than design tables from manufacturer, maybe something in between.

Any comments are welcomed, kind regards.

How are you fastening the pieces together?

Shop welded but it was just an example

There is a software program called "CFS" that may be of help.
