Composite HSS Design Properties
Composite HSS Design Properties
(OP)
Does anyone know a good reference for transformed section properties of a concrete filled HSS? I know the LRFD manual gives design values for compressive loads. Any help would be greatly appreciated. Thanks in advance.

1. Look in the AISC DG on composite columns. I don't know if those are included, but they might be.
2. The AISC Manual gives tables of phiPn as you mentioned. At the bottom of the table is a value called Pe(KL)^2/10^4. I think you can use Pe=pi^2*EI/(KL)^2 to back out the moment of inertia.

Also, for rectangular, the transformed MOI calc should be borderline trivial, so I'd probably just take a shot at that if nothing else.
