A quick background to the problem: A client of ours is experiencing floor heaving in their pre-manufactured steel building due to pockets of slag under the spread footings. Because of this, a few of the steel columns have deflected over the last couple years. This company hired us to perform a feasibility study on repair/monitoring options available to them. The building is only about 5 years old.
Now to the question: My boss is convinced there are AISC codes out there that specifically relate to post-construction plumbness tolerances for pre-manufactured steel buildings...and he's tasked me with finding them. The closest number I could find was L/500 for construction tolerances on rolled steel shapes. However, the columns we are dealing with are not rolled shapes; they are pre-manufactured columns with varying sections that are super-engineered to a KL/r of like 199. Can anyone point me in the right direction?
Sorry if this question is a bit dumb...I have only been in the field for about a year now. Thanks for all your help!
