Stiffened Flat Plates and AISC Code
Stiffened Flat Plates and AISC Code
(OP)
Does the AISC code contain provisions for the design of stiffened plates subjected to out of plane bending such as plate buckling and local yielding? If not, does it make recommendations on which code to adopt?

The theory shall be the same for either cold formed or hot rolled thin plates, am I wrong? Is it warp or buckle under compressive force? Just curious.
RE: Stiffened Flat Plates and AISC Code
The plate is a flat plate stiffened with longitudinal and transverse plates. The loading is applied through connections to the plate which transfer both moment and compression.
The copy of the AISC I have makes no mention of stiffened plates so I expected that this would be outwith the scope. I wondered if it had a reference to another code.
The client would like us to use AISC.
If there is no guidance in the code then it falls to me to select an appropriate code and propose this to the client. In which case I would be leaning toward EC3 or DNV RP C201.
RE: Stiffened Flat Plates and AISC Code
You're right, the theory is the same. But the cold formed steel industry uses a lot of thin plates, while AISC generally uses stockier elements. So AISI has more sophisticated plate buckling provisions. At least, that was the case 25 years ago.
