Interaction curve(4-point) for filled composite columns-Any example?
Interaction curve(4-point) for filled composite columns-Any example?
(OP)

The code suggests creating interaction curve (4 points A,B,C and D)
I have trouble creating these points for a circular filled column. Should be circular
Anyone knows of a good reference or a web site.

The interaction diagram will not necessarily be circular (RC circular column diagrams are not circular). You should be able to create the unfactored diagram based on trial and error using allowable stresses, say using Excel.

for a discussion and some instructions (slides 38-50).

Thanks for the link
I didnt mean a "circular interaction" diagram. I meant interaction diagram for a "circular column". I need plastic moment and axial capacities at the 4-points mentioned in AISC'05.
The expressions is what I am looking for

A friend of mine gave me those equations.
But if you use the equation you will see that theta value comes too large. Try any column size.
Either the formula is wrong or I am missing something, probably the later.
