SAP2000 - modelling springs 1

[MDSAP2000]

Hello

I have two questions :
-the first one
I'm working with SAP2000, I'm modeling a deep foundation, the soil is modeled by springs. the stiffness of the spring, changes as the case of load. how can it be done in a one model?
-the second one
How we can display moving loads (statiques loads)

thank you for your answer

First Q:
I believe you need to define a separate spring for each level of soil with different stiffness at each level.

Second Q:
To show your moving load, I believe you can look at your vehicle load, and how you have defined that.
The loading doesn't show on your model as it's a moving load. You can look at the Moment and Shear as a result which is an envelope of your moving load effect on the structure.
