Built-Up Shapes in AISC
Built-Up Shapes in AISC
(OP)
Hi Guys
I got a wierd question from our customer that where in the code of AISC that actually ALLOWES built-up shapes in the structure. In my case, the built-up shape is column and beam that welded from plates.(similar to plate girder).
Anyone knows where I can find a statement that I can use built-up shape in design?
I always think it's common sense that if rolled shape is not available, you have to use something builtup. But this customer is just strict on it.
Thanks

On the other hand, if you're the fabricator and the design calls for rolled shapes, you can't willy-nilly substitute built-up shapes on your own say-so. You need to get the client's or designer's approval. But they should give it as long as you can demonstrate that your built-up piece has the same properties, that its connections can handle the requisite shear, etc.

Chapter D, Tension Members, Section D2, "Built-Up Members"; Chapter E2, Columns and Other Compression Members, Section E4 "Built-Up Members", Chapter F, Beams and Other Flexural Members, Section F7, "Built-Up Members"... And of Course Chapter G, Plate Girders... which are BUILT-UP from PLATES connected by welding or fasteners.
If that doesn't satisfy them, get another client.
