Re: HSS column splice

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Fellow engineers,
        I'm the last person anyone should take critical welding advice from; but, if the weld is that critical and you absolutely must provide a solution, why don't you put in a full diaphragm 4x4x(say 0.5"thick) inside one of the HSS and protruding into the other HSS, assemble the components, then do the weld?
        Just a thought.  If it's a really bad idea one of you can let me know.

Why not just use an HSS 6x6 sleeve instead?

I'm doing a column splice detail.  I'm told that lengths over 20' in a 5x5 tube steel aren't available around here.  The splice will be just above a floor diaphragm, and I will be able to block the column into the floor framing pretty well.  I'm considering using a sleeve from a section of HSS that is larger than the column section.


Anyway, will an HSS 5x5 fit inside an HSS 5.5x5.5x1/4 sleeve?  Has anybody else out there done this?
