Checking Baseplate connections
Checking Baseplate connections
(OP)
Hi guys,
As you will see in the attached picture, the SHS column is in line with the bolts of the right side of the plate, I am checking this design and I don't think it is right to place the column like that, so to solve this issue I was wondering if it is possible to add 2 additional bolts in the centre line of the plate? .
the axial load is about 12 kN moment is 0.75 kN.m.
Any advice would be appreciated

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 plate thickness is 10 mm.
Please if you could provide me with hand calcus illustrating your thought

If the load is reversible, the bolts could be in tension. (Not considering the vertical load because I don't know whether that is a uplift or down load (or both).)
I'm not sure I follow what your objection is to the column placement. Yes it is eccentric.....but I doubt it was done just for the sake of having a odd looking connection. And there is nothing in code that forbids it (as far as I know). I'd just run the numbers on it and be sure it works as far as strength goes. (Be sure you have enough space on that edge to get your weld in. That caught my eye.)

Please if you got any worked example similar to this case, provide me with it that will be very helpful

Why not do a hand (or FEA) solution? You could make a fairly conservative assumption as to the width of the plate that resists the applied moment (maybe the width of the column) and superimpose that stress on the stress caused by the axial load.
RE: Checking Baseplate connections
you have P and M = M +/- P*e, e is distance from center of column to center of plate. Critical bending in the plate may be from the long side at the face of the column.
