Hi everybody,

I have created a model in Caesar of an existing pipework.
There are two hanger in this model.
I know that Caesar can design the hangers, but the results do not match the information that I have about the Hangers. Hence, I thought to pre-design the hangers in order to obtain a model that is more similar to the reality.

I found the catalogue of the variable spring hangers so the data that I have are reliable.

Caesar ask me 2 things to pre-design the hangers:
- Spring rate (and I have it)
- Theoretical cold (Installation) load.

I imagine that this last parameter correspond to the load that the hanger see when only the weight of the structure is considered.

So I thought to run a simulation and read the reaction of the restrain in the node of the hanger when only W is considered and use this data as input to pre-design the hanger.

Is this process correct?

(Hope to have explained myself)
Regards,
Ilario
