crushing load on hss
i am reviewing an application that uses a hss8x4x1/4 as dunnage to distribute a 38 kip load across a solid mat of 6x6 timbers on a slab on grade.
can someone point me to a reference for checking the "crushing" effect of this load on the hss?
the load is applied by a shore leg with a 5-7/8 square, 3/8 thick end plate.

check out our whitepaper library.
excellent book, "hollow structural sections connections and trusses" by packer and henderson and available through the cisc in canada.

a concentrated load on a tube won't take too much. if you want to analyze it (by yield line) refer to blodgett "design of welded structures".
personnally, i would just weld a thick face plate on the tube to adequately transfer the load to the walls.
aisc 13th chapter k and the commentary may be a little help.
