Rebar Requirements

Rebar Requirements

Rebar Requirements

I am designing a concrete columm to support (4) 12" x 12" timber columns that form a square with 6" space in the middle.  The Timbers have a small compressive load (3K each) and are only this large for aesthetics.  Ideally I would like a 30" x 30" x 72" column on top of a footing to support these timbers and attach stone work to.  

To meet ACI reinenforcement requirements a a large amount of rebar is needed since the column is so large even though the loading is minor.  

Is there another way to approach this problem so I don't need so much rebar?

RE: Rebar Requirements

You can still design under code for up to one-half the minimum compression steel if you use one-half the section properties (ACI 318-02 paragraph 10.8.4).

RE: Rebar Requirements

Can the conc stub be considered as a plain conc pedestal?  and then chuck some rebar in for comfort?
