Most efficient and minimally disruptive way to strengthen a weak RC column in a moment frame.

Most efficient and minimally disruptive way to strengthen a weak RC column in a moment frame.

Most efficient and minimally disruptive way to strengthen a weak RC column in a moment frame.

(OP)
I would like to know what is the most efficient and effective way to strengthen a weak column in a COMPLETED building without increasing the weight significantly as well as the disruptive work.
I am proposing, using steel hunches around the top where it interfaces with the beams and use FRP wraps along the length of the column. Any comments will be greatly appreciated.

RE: Most efficient and minimally disruptive way to strengthen a weak RC column in a moment frame.

Can you use FRP?

RE: Most efficient and minimally disruptive way to strengthen a weak RC column in a moment frame.

When you say its a weak column, what exactly is it short on capacity for, bending or shear or axial capacity or all three or a combination of two? Are the beam/column joints also insufficient?

FRP wraps for example might only address insufficient confinement and not improve shear or bending capacity?
