concrete filled steel columns
the new steel code has 115 pages of tables for axial capacity of composite concrete filled tubes, hss, pipe columns, etc. from what i can see in the tables, there doesn't seem to be a whole lot of axial advantage to doing this. does anybody use these, or is my steel code just 115 pages thicker than it needs to be?

there's not much difference in axial load capacity for short, thick-walled tubes. but there's a big difference for slender tubes.
