VERTICAL DUMMY LEG ON BEND

I'd like to know your opinion about modeling vertical dummy leg on bend among three ways explained in Caesar II Application Guide:

- Near point method
- On curvature method
- Offset element method

I usually model vertical dummy on curvature method. I do it because during assembly I believe it is impossible dummy leg is perfectly lined up with centerline of vertical pipe (near point method) and then I consider this "ghost" moment in my analysis but taking care if a nozzle pump is particularly near. Only in this case "ghost" moment coul be unreal.

Thanks

Can you give me your opinion?

Thanks

The three methods as you have listed vary from:

"easiest to model but less accurate"

to

"most involved to model but most accurate".


For most systems, the "on curvature method" should be sufficient.

Thanks Richard

Dear Mr. Richard,

sorry if I ask this (maybe a stupid question).

I already read that c2ap.pdf,

i saw: when Near Point Method DY= 8ft 6.000 in

but when On Curvature Method DY= 7ft 7.390 in

where that DY= 7ft 7.390 in came from???

please help...
