how do you reduce the capacity based on corrosion?
how do you reduce the capacity based on corrosion?
(OP)
Some of the members but most importantly the Anchor bolts are corroded.
This structure is sort of abandoned for sometime where they removed all the equipments but now they now want to use it again and add another level.
Grating is actually heavily corroded but that doesnt concern me.
I am concerned with some anchor bolts.
Also there is water leaking at the upper level and this set of anchor bolts are always wet and is now corroded. The column is corroded also but not that bad.
I wanted to post pics but cannot. Company Policy is strict.

If that means that the whole structure is unable to sustain loads, that is what I would say. If it needs major repairs to get it up to code, sometimes we have to convey bad news.

Plus, I would state that whatever I can't see (below the concrete surface) is of unknown quality.

other structures in use are just as old but well maintained (minimal corrosion).

i have no experience about replacing anchor bolts. i have done adding new anchor bolts.
so how is replacing done? can i just say remove these anchor bolts then replace new hilti bolts?

How are you going to treat the corrosion at the base of the column and is the structure located in a corrosive environment.

There isn't much you can do about the part you can't see.

RE: how do you reduce the capacity based on corrosion?
it's probably because it's abandoned for sometime and it was not galvanized. also if you look at the way it was moment connected to the base plate (no plate washer) the oversize holes caused dirt and water to go inside.
anyway i'll just add more anchor bolts and have the base plate repainted.
any more inputs and advice will be appreciated.
