galvanized tube column base plate
galvanized tube column base plate
(OP)
Has anyone done a check on the base plate for a galvanized tube column? The shop drawings for the base plate showed a solid plate, but the entire inside are of the tube is removed from the base plate to allow for galvanizing (which was not shown on the shops). I would imagine there is more concern than just the bearing area left, but am unsure exactly what that check may be.

I agree with BA. Furthermore, on the compressive side of the column, the base pl. bending will pry on the root of the fillet weld btwn. the base pl. and the HSS, it will cause tensile stresses across the root of that weld, never a good thing. On the tension side of the column you do not have the continuity of the base pl. beyond to help distribute the bending moment into the HSS and the base pl. beyond. They should have drilled a drain hole in the base pl., not cut the whole thing out inside of the HSS. Is there a significant bending moment on the column? Does the base pl. bearing check? What are the member sizes, weld sizes, loads and moments?

At first look I thought some lateral columns came into the mix but that wasn't the case. If it were I can imagine many more issues, but in the situation I think I am ok.

Wouldn't a couple of small weeps take care of the galvanizing issue? Why cut out the whole plate?
