hi there,

Some questions for the execution of Earthquake Spectrum Analysis...
Should I include the Nodes of the Equipments Models or ONLY the Piping Nodes ?

What happens when Gussets exist on equipment model ?

thx

That depends on the type of equipment and how you model it (the equipment). Remember that CAESAR II models are composed of 3D beam elements only. If you model the equipment (pumps, etc), you typically use a series of rigid elements with an anchor at the base, and the your piping to the nozzle node. This model should be good for both static and dynamic analysis.

If you don't model the equipment, then it is up to you to provide (static) nozzle displacements. The dynamic model should be acceptable as well.

CAESAR II is unaware of gussets, but these won't affect the (CAESAR II) equipment model, assuming you have used rigid elements.

Its time Caesar include in Static/dynamic load case combination
S1+D1 ; S1-D1 for the restraint loads and find the max values from both!
I must allways this do with Excell !

A reasonable request. I will make note of it.
Thank you.

If possible make also a note for this:
We have most 2 dyn. load cases XY and ZY an must find the max values
over this 2 load cases.
