W-section base plates for a small Metal Building
W-section base plates for a small Metal Building
(OP)
A few questions in my base plate analysis. I know that you can design a structure with a pinned reaction in a structural modeling software. However, does an engineer test to see how much moment COULD be transferred to the base plate, or does he just assume if fully braced, use an inside four bolt plate reaction? I originally started my design with a large moment resisting baseplate, then found out that my 16 inch grade isn't large enough to support a large moment baseplate. So do they not typically design small metal buildings with a large moment baseplate on a W-section column?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

The article itself smells a bit fishy to me (wondering what you opinion is Kootk?) but you get the gist of the method which I think is good.
I myself dont use it yet, for now its just nice to know it exists, as an ace up the sleeve, if I find myself cornered-in...

Just got around to reading this article. Thanks for sharing it. Two interesting takeaways:
1) Base plate stiffenening seems to not greatly affect base connection flexibilty.
2) Apparently a two bolt pattern does reduce base connection stiffness to the point that a pinned assumption makes sense. That's contrary to a long held view of mine.
At least, these are the analytical conclusions of the author. I'm not really in a position to comment on any potential "fishy-ness".
