soil-structure interaction in sap2000

[samira155]

Hi Dears
I want to model soil with solid elements in sap2000, I am confused
in my model I have a rigid block on layerd halfspace
how to connect the soil elements and the structural element in sap2000?
how to model block elements same as a rigid body?
how to define soil material in order to it's mass not considered in analysis and only its stiffness considered? if I put mass density per voulume equal zero... its ok?

I have many QUESTIONS

These sound like perfect questions to be asking the Bentley support staff. I have found that our structural software support team to be very helpful and informative when it comes to direct modeling questions.
