Nonlinear analysis for compression-only soil spring
Nonlinear analysis for compression-only soil spring
(OP)
If a sap model has involved compressioin-only soil spring, does it need to run non-linear analysis for every primary load case and all load-combination cases as well?
I have modeled an underground tunnel in SAP, and there are quite a lot of soil spring (compression-only) defined. I appreciate if any comments.
Thanks.

You should be able to easily see this in the output of the model (the compression-only springs will be taking tension if you don't run non-linear).
