Regarding spring element

Regarding spring element

Regarding spring element

(OP)
Anyone has modelled spring element is SAP to get a vertical mode shape in Up and down direction? If yes, How to model those elements?

RE: Regarding spring element

What is a spring other than just a beam/column element? If it has equal stiffness in tension and compression, you can just make a custom material/section properties combo that gives you the correct stiffness of the spring. Add a mass and supports then you can do the modal analysis.

If your talking about foundation springs or something like that than perhaps I haven't understood your question properly.

RE: Regarding spring element

(OP)
Thanks for your explanation. Not foundation springs. I am modelling a cooling tower like structure. For that spring elements are needed
