Structural Integrity Management
Structural Integrity Management
(OP)
I am finding very little documentation when it comes to long term structural steel integrity. It seems to be an area with very little regulatory requirements. Codes specify that it is to be designed to a certain criteria with a suitable corrosion resistant coating. The coating applied will provided many years of protection but will eventually fail. The most advantageous response is to recoat the steel before any significant corrosion has occurred. Unfortunately this is difficult and has not been done in many industrial setting.
Since any corrosion will diminish the safety factor, is there any industry standard to say what amount of corrosion is acceptable without doing fitness for service calculations on every member?
Does anyone know of any good books or documentation that has proper ways to support and repair structural steel while under load?
Thanks in advance.

Also, check out "Structural Renovation of Buildings: Methods, Details, & Design Examples" by Alexander Newman. It has a ton of great info. My copy is at home or I'd give you better info now!

This is just a random image off Google but imagine this after 20-30 years of exposure to water and salt. You would have extensive paint failure and corrosion. With the amount of water exposure from the process it almost borders on submersion. I am not looking at ways to prevent the corrosion, I am trying to find an industry standard that is used to mitigate risk by replacing or repairing when members are reach a certain level of corrosion. Fitness for service calculations can be done, but they are very time consuming.
