Estimation of tensil force on a ring beam
Estimation of tensil force on a ring beam
(OP)
Hello everybody
My question is quite simple but I want to be sure. Thanks in advance
i have a ring beam supporting a circular equipment. The equipment is connected to the beam by bolts.
a horizontal force on the equipment vessel generates a moment.
i want to know what is the linear force distribution (of course compression and tension) on this beam due to the moment.
Many many thanks

If your question is about finding a closed form solution for moment and outwards force at some point of a ring, there may be for your kind of support in the mechanical handbooks. A sketch would help us to find it if we try.

I want to know the distribution of forces on a ring beam .
I know there is a formula but I m not sure and I do not want an approximative methode.
Let s call:
M : Moment applied on the beam
D : Diameter
R : Radius ( D/2)
So what is the linear forces applied on the ring beam regardless the material .
i attached a sketch to make it clear
Many thanks
RE: Estimation of tensil force on a ring beam
if the ring is very stiff (well supported to the rest of the world, egbolted down to a contrete base, big bolts, close pitched) and if the circular equipment in also stiff then the moment will be distributed around the perimeter, yes?. a reasonable assumption would be "plane sections remain plane", so that the individual foces would be proportional to the distance from the diameter they're bending about.
clear as mud ?

That should be enough (codes permitting) but there's much info about bolt connections with bolts in circular arrangements out there and you can search it in the internet to suit even more the case.

Actually, the formula I was looking for is in page 7 of your document
So perfect
Thank you so much thanks everybody

Since the system is apparently indeterminate, the stresses in the ring beam are a function of the relative stiffnesses of the equipment, beam, fasteners, and support. If the formula you are using doesn't consider this then you still have only an "approximate" solution.
just sayin...

Everyone knows this is approximate. If you want "exact", then you're forced to account for soil stiffness, foundation stiffness, and a lot of other factors, all of which are approximate at best, so you don't necessarily gain anything but complexity.

the problem you are dealing with has been addressed in "Pressure Vessel Design Manual" By Dennis R Moss
