Tube to Tube Connection
Tube to Tube Connection
(OP)
I have an unusual detail where I have a HSS 16x8 vertical member sitting on top of a 16x4x1/2 horizontal member.
The load in the vertical member is small, at only 27 Kips max.
I am trying to be sure I'm comfortable with the vertical sitting on top of the horizontal. I don't think its likely that the 16 x 4 walls would buckle, given the short 4" dimension, wall thickness, and the continuous 16x4 member, but I am unsure how I could check that numerically if I wanted to.
The horizontal member is 20' long. There is only one 16 x 8 sitting on top of the 16 x 4, and that's at the mid-length of the 16x4. The 16x4 is continuously supported by the W21x93, and, has a W16 x 26 at the centerline of the 16x8/16x4 to aid in supporting the 16x8 and to prohibit the 16x4 from rotating.
I'm I over thinking this....and am concerned over the 4" tall wall for nothing.....given the small load?
Thanks for everybody's input.

As best I can determine, Chapter K does not address this situation.

The actual b/t is 4/0.5 = 8; 8 < 25 OK. Appendix K of the 9th edition deals with determining if web stiffeners are needed and how to size them.
