Headed Shear Stud Length
Headed Shear Stud Length
(OP)
I've got a project where nearly all of the project is composite beams. The typical deck is 2" composite metal deck with an additional concrete coverage of 3 1/4" (5 1/4" total thickness). My headed shear studs are 4" long and 3/4" diameter.
But,
I have a portion of the building where I needed more mass, so, I thickened the composite slab to 8" thick. So I have 2" metal deck with an additional concrete coverage of 6" (8" total deck thickness).
I have designed the thicker slab area also using 4" studs, but then I started thinking, should I use a 6" long stud? Is there any reason to go to a longer stud?
I can't think of a reason to use 6" headed studs, but this has been bugging my mind. What do you guys think?

RE: Headed Shear Stud Length
For the maximum length studs, see "Concrete Cover for Steel Headed Stud Anchors", in the May 2013 issue of AISC's "Modern Steel Construction" magazine.
For minimum length, see "Short-Headed Stud Anchors", in January 2017, "Modern Steel Construction".
