Bending moment calculation
Bending moment calculation
(OP)
I want to manual claculate the bending moment ( in-plane , Out-plane) of piping isometric consist of vertical pipe attched with flange and horizontal pipe with elbow which atached to previoud pipe ,what eqyations are used for calculation

also how to calculate moment loading range to calculate stress due to displacement range
RE: Bending moment calculation
Kellogg's or LC Peng's books will help with something of this nature.
The isometric gives no indication of what the flange at the one end or the valve at the other end is connected to. You will need to establish the boundary conditions there.
I am amused to some degree by the statement on the right hand side of the isometric:
"DESIGN DATA - COOLING AND EXPANSION EFFECT: NONE".
Looks like someone's already decided that there is not a problem here.
Light-heartedness aside, this would be just like an example problem straight out of Kellogg. See Stanier's post for the link. Good for you to want to do some hand-calculation-verification of computer output. That will ultimately separate you from a lot of other engineers.

so , what is the bending moment at each node

Spend the 18 bucks get the book and calculate it. We are not here to do your work for you!

Use the English units and convert to whatever you want.
Structural analysis discusses many hand methods, a number of which are the same used for computer pipe stress analysis.

Computer programs (CAESAR II, CAEPIPE, etc.) do a good job of setting up and solving the matrices and so forth, but the methods still work.

Its far easier to convert dimensions and parameters to Imperial units than find the information you seek in SI units.

Alternatively you could invest in Caesar II, Autopipe, Triflex etc or pay someone who does know how to use the software.

RE: Bending moment calculation
The main subject is how to calculate piping stress analysis manually then check it using Software such as caesar II , to give you same result
what the equation used in calculation of forces and moments in caesar ?
