Existing Pipe Column Strengthening
Existing Pipe Column Strengthening
(OP)
I have an existing 6" Std Pipe column that needs to be strengthened. I am semi familiar with the strengthening of a wide flange column but am not sure about a pipe column and if the design method or detailing is different.
Any help or advice would be much appreciated.

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.

A simple test would be to fill a Shelby tube with grout and run a column type compression test in the concrete test lab and it will demonstrate what goes on.

a new inspection port a the top. No worries.

Depending upon the exact weakness of your 6" Std. pipe col., you might consider 4-2x2 angles, toes in, welded to the pipe. No greater in square size than the col. dia. and they can be oriented to fit within a wall or oriented to best strength advantage. Non-shrink grouting from the bottom up also adds compressive strength and improves buckling conditions.
