The "Newman Lug"

[bones206]

Has anyone ever used this approach for column baseplates (particularly for PEMB's)?

If you've read the book you know what I'm talking about. Basically a leveling plate with a shear lug. I can see the pros but wondering what cons may be lurking...

I didn't realise the base plate was welded to the insert plate with the lug... first time I've seen that.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

The issue with using a welded plate washer in this application (a PEMB), is that now you're messing with the PEMB manufacturer's stuff. It's one thing if you're the EOR and specifying the PEMB. Then you can tell them to give you oversized holes and welded washers. If you're just the foundation engineer brought on after somebody already bought the building (common for agricultural buildings and oversized garages), it's hard to do that. And I the last thing I want is a problem with the building performance to be blamed on my telling them to weld something, which I'm sure voids a warranty for a lot of the smaller outfits. Then again, I'm not sure how welding the base plate to the lug plate would work in that regard.
