Dr Ezzeldin

There are useful guidelines, recommendations and equations in the AISC.

Nasir Shafiq

In the attached document the the last section discussed in detail about combined Beam-Column design, which may be applicable to built-up sections as well

Messaoud Saïdani

Dear Izzeldin,

The Eurocode is a good start, and the article suggested by Nassir Shafoq above is a very good one to start with.

I would just add that designing buil-in beam-column is essentially down to designing the connection beam-column, and therefore I would look into documents of steel connections design.

Best wishes with your research.
