Dear Friends,
Apologies if you know about this but if you don't than..
I have found a new concept of designing Suppor Leg.
The best way of using the pipe as a leg is to cut or notch out the pipe wall - removing half of the width of the pipe - and lay the pipe up the side of the vessel shell.

But Does This means that the line of action of the weight from the vessel coincides with the centroid of the pipe leg and so there is no bending moment transmitted into the leg and baseplate ????

Bending moment of half round

B = My/I , taking I/y =section modulus=z
B = M/z


Can this simplify the calculation to only for shear in the attachment weld and buckling in the pipe leg ??

Any further, pleae let me know.

Hello tseco123,
Do you mean a vessel support like this:

I agree that it´s a clever way of attaching the legs to the vessel wall, although the commonly used design rules do not consider the part of the pipe which has been removed. I would appreciate if someone has an idea how to include this "weakening" in a calculation.
