Common RC Column Configurations
Common RC Column Configurations
(OP)
I'm trying to put together a matrix of the most common RC Column configurations. Here is what I have so far:

With the circular columns is it more common to weld the transverse ties into circular hoops or to just hook the tie around adjacent longitudinal bars. I don't have a lot of real world experience with RC so I'm learning.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

For your third square column, you would either need 2 crossties or none at all (assuming you don't have more shear in one direction than the other). If clear spacing between bars exceed 6", you need them to be "tied"
Same for the rectangular columns.

Must be alternate ends where there are multiple of them in one direction and their use is limited based on concrete strength and axial load in ACI318-2014.
Otherwise, 135 degree hooks are required at both ends.
