RE: NC coastal condo building - condemned for steel corrosion
That isn't really true. If you lose half your section of a column, the buckling load would be reduced by more than half. With thinner flanges, etc. you could have way less than half capacity with localized buckling.

Depends on the loading condition. If you lose half your area mid column your buckling load can be greatly diminished... at the ends, if pinned, not so much.

Agreed... as Mike noted for rigid frame construction; the localized buckling is a bit dependent on the moment at the cross section in play.

In the 13th edition (and I'm sure other editions)of AISC Steel Construction Manual, the Corrosion Protection section under General states, "In building structures, corrosion protection is not required for steel that will be enclosed by building finish..." When is this statement not true?
Are the structural engineers / architects liable for assuming industry-accepted practice applied to their building, and coatings were not required.
Steel 0
Concrete 1

IMHO, when the "building finish" comprises stucco.

I've encountered chemical plants where birds could fly through the webs... worse than an OWSJ...

After flooding with salt water, architectural covering and coating just accelerate corrosion - year round high humidity together with the salt that remains in the coverings ensure that the steel stays both damp and salty.

How so? Wood has to be connected with steel, and wood also deteriorates with moisture, so if the same cladding system is employed, wood would suffer the same fate.

I use to visit that area decades ago and there was a large test facility (acres) for environmental exposure corrosion testing on that beach front strip. I guess the property values got to great and condos replaced it!

I would of never thought that steel encased like that, even in stucco, would corrode that badly. I can't help wonder if there's another issue causing the problem. Is the stucco of extremely poor quality?
RE: NC coastal condo building - condemned for steel corrosion
I have been looking at houses here in Houston, which is very humid and stucco I am told is not good in moist environments. People have stucco houses here because they like the look but you have to watch them. There is a townhouse complex down on montross that you can literally peal off the stucco wit your hands. There is another place we thought about bidding on and then passed when our realtor got a hold of a stucco report for the house and it looked like it needed 100k of work. Maybe, I am wrong but why would you put a stucco building on the shore?

The insurance policy got to rubbing up against that engineer's report.

The poor building has been in a collision where; unprotected steel, bad stucco, saltwater, hurricane winds, and modern paint all came together.
