Carbon Fiber Wrapping to repair corroded steel structures
(OP)
Hi all,
I need to repair the angle steel and I-Beam which are heavily corroded plus metal loss, it is for overhead pipe rack, this is an old LNG plant where these steel structures had never been changed since the last 25 years. I'm currently looking at repairing these steel structure by using Carbon Fiber Wrap; I know this method has been widely used but I just couldn't find any calculation to support my proposal, can anyone here help?
I am familiar with PCC-2 but it is for pipes, not steel structures.

One would think that you would have to have a structural prepare the calculations for you.
The repairs outlined in PCC-2 are for non-hazardous applications. Hard to see how repairs to a piperack in a LNG plant would be considered non-hazardous. Pipe supports in plants handling flammables are generally constructed from concrete.

You might do some research into earthquake remediation, and this is common there.
This is a very labor intensive process, much more work than building steel structures.
And they will be almost impossible to repair or modify in the future.
I would see this as a last option.

Ya, it will make it unable to be opened up for repair and maintenance, even inspection I will need something intense to do so..

It is the Young's modulus (stiffness) of carbon that is significantly higher (30+ msi versus 10 msi). Matching stiffness is important to sharing load properly.
