Composite HSS Sections
Composite HSS Sections
(OP)
I'm looking for section properties of concrete-filled HSS and other steel pipes. Is AISC Design Guide 6: Load and Resistance Factor Design of W-Shapes Encased in Concrete / Griffis (1992) applicable?
Any other info is appreciated.

I suspect that things get a bit more complicated if designing to the plastic yield or ultimate limit states.

From a web search, I came across a British (I'm an American, working in the US of A) design manual, entitled "Design Manual for Concrete Columns" that has an excellent section on computing ultimate moments for concrete-filled pipes. Very interesting, indeed.
For my work, though, I started with allowable stress method, using modular ratio, etc. The British method, as explained in the manual (I think I got it off the Corus Construction web site, but alas, I can't remember nor do I have a record of the link...) is intuitive and jibes well with what I'd expect. It also, bless them, has an extensive table of ultimate moments as well as enough caclulated section property data to verify that my own calcs are correct.
I will, though, bite the bullet and pick up the AISC manual I mentioned, eventually...

The HSS chapter of the LRFD manual didn't seem to provide enough theory regarding bending of filled HSS, nor did chapter 4. Mostly it's concerned with these members as columns. Though there are design flexural strengths shown for some filled HSS - but not the one I need to use in an unusual application.

One acronym that might be helpful in your searching is CFT (concrete filled tube).
