Adoption of AISC 360-05 Adoption of AISC 360-05 Ussuri (Civil/Environmental) (OP) 26 Jan 10 08:39 How widely adopted and used is the AISC Specification for structural steel (360-05, 13th edition I think) in relation to the AISC 9th edition green book? RE: Adoption of AISC 360-05 WillisV (Structural) 26 Jan 10 12:29 Every state has adopted some form of the IBC (http://www.iccsafe.org/gr/PublishingImages/Adoption_Maps/map-IBC.jpg). The vast majority (37 or so out of 50) have adopted IBC 2006 or 2009 (http://www.iccsafe.org/gr/Documents/stateadoptions.pdf)So - since the IBC 2006 and IBC 2009 reference AISC 360-05, that is the required building code in those states, and it is illegal to use the 9th Edition Green book for building design. RE: Adoption of AISC 360-05 LowLax (Structural) 2 Feb 10 22:06 Is it really illegal? Can someone put you in jail or fine you just for using an old code? I thought it was the engineers responsibility to design the structure using whatever methodology they want. I bet there are a lot of older engineers out there using old material, or maybe I'm completely wrong.

RE: Adoption of AISC 360-05 nutte (Structural) 3 Feb 10 10:05 The alternate viewpoint is that your design has to comply with the applicable code. If designing per the 9th edition gives you a result that still satisfies the requirements of the 13th edition, then you're in the clear. A better way would be to say "it is not permissible to design per the 9th edition while forsaking requirements of the 13th edition."It's definitely not up to the whim of the designer as to what code must be satisfied. RE: Adoption of AISC 360-05 ishvaaag (Structural) 3 Feb 10 11:57 In Spain it would be permissible to NOT comply with the specifics of the current documents within CTE since there is a waiver that permits the designer to use other methods as long the general (and all encompassing) goals of servicibility and safety mandated therein are met. It remains to be seen if that means as well or exactly, as measured by the elsewhere expressed requirements, and not less, but that could be a quite probable interpretation in litigation.
