Strengthen Existing Concrete Column
Strengthen Existing Concrete Column
(OP)
I am looking for the best way to strengthen some existing concrete columns. I am working on an existing concrete piperack with 1'-10" square columns. New equipment will be added to the existing structure. The wind loads introduced by this new equipment are causing the bottom 4 ft of the columns to require more reinforcing than they currently have. Bracing cannot be added to to clearance constraints. I was thinking of adding large channels to either side of the column and through bolting them. I was just wondering if anyone had some other ideas?

On top of ductility for earthquake ( which fyfe uses glass fabrics) it could also be used to increase the axial capacity. I have done some experiments on it and well for round columns, usually you would be suprise about the strenght that it could increase.

I realize you have clearance constraints, but you'll likely have to dowel into the base or provide a supplementary steel collar as a base for your repair tie-in.
