Corrosion repair of CHS 5

[NewGuy132]

I'm new to brownfields mining projects and one of my first tasks is dealing with some heavily corroded CHS vertical braces on a multi-storey stairtower. These braces have holes on them which I can stick my hand in. Does anyone have suggestions for the best way to repair this? Or does it need whole member replacement. I want to avoid whole member replacement as I've no experience with the methodology for removing existing braces which may or may not be under load. Thanks for any advice.

I'll have to say I have never been "accused" of under designing anything... at least not on purpose.

I can believe that. Most of your posts that I have seen have been great and I have little doubt that the length and breadth of your experience is greater than mine.

I'll accept that I underestimated the maximum axial load that the angle can resist.

And I pounced on the oversight. Sorry! This is an area that I know pretty well without calculations or tables. I regularly use SHS,CHS and EA in compression bracing so I have a decent feel of what works and what doesn't and when EA is cheaper that SHS/CHS.
