UG-44(b) RESOLVE MOMENT VALUE CALCULATION BASIS REQUIRED 1

[staticmh]

Hi Folks!

I'm calculating the UG-44(b) flange external load calculation manually. So pls refer to attached link and red color mark.

I just need to know that how "Me" resolve moment value is PV elite calculating. Since the Nozzle load for the available nozzle sizes are below:

2"

Fx = 1 KN
Fy = 1 KN
Fz = 1 KN
Mx = 0.380 KN-m
My = 0.380 KN-m
Mz = 0.380 KN-m

6"

Fx = 3.8 KN
Fy = 3.8 KN
Fz = 3.8 KN
Mx = 3.7 KN-m
My = 3.7 KN-m
Mz = 3.7 KN-m

The resolved moment is the resultant flector moment: 0.38k N.m = 0.38*1000*1000 N.mm*sqrt(2) = 537401 N.mm.

When you purchase a program such as PV Elite, isn't a operator's manual explaining the program provided by the seller?

@Morcuse, Thank you for give an fantastic quick calculation basis of PV elite resultant moment.

But what is the formula and any book reference from which they are considering.. ?

As per my understanding the formula of resultant forces and moment is something different.

But as you quoted "0.38k N.m = 0.38*1000*1000 N.mm*sqrt(2) = 537401 N.mm " is quite accurate but i'm unable to understand the formula basis and reference.

Could you please refer the formula basis / reference of this resultant moment calculation..

Thanks in advance.

@Chicopee

Unfortunately, this information is not available in operating manual or any help forum nor on some other areas..

If you know any reference, please share with me.. i shall be go through it to understand the basis.

The resultant flector moment is sqrt[(My^2)+(Mz^2)], when My=Mz, the formula just becomes M*sqrt(2) - everything else is unit conversion factors. On the other hand, no resultant force calculation is needed for "F", because the 2019 Edition UG-44(b) method only considers the external axial force.
