concrete filled tube composite section
concrete filled tube composite section
(OP)
I have a canopy for a walkway that cantilever's up from a single column, up over the sidewalk. Because of the loads I cannot get a size the architect likes for the column. Does anyone know a way to bond concrete that is filled inside a tube in order to increase the bending moment capacity?

I downloaded the design tables, and a few more. Thanks for the link. But at the top of each table states that the loads in the tables are CONCENTRIC. I have moment and axial load.

Good Luck

There is a paper by Bradford in ACI Structural Journal #93/2 March /April 1996 pp 229-235 using strain compatability approach for axial and moment strength of short rectangular CFT's. It references a paper by Tomii et al in Japan Concrete Institute proceedings on bond issues.
Unfortunately, I do not have the Tomii paper so I cannot comment on what are significant bond issues.
HTH a little.
