Foundation Stiffness matrices

[novs]

I am designing the foundation for a 9 span structure, where I am required to provide foundation stiffness matrices for each pier.

This is my first job utilizing foundation stiffness matrices. I am looking for a recommended method or reference to complete foundation stiffness matrices, from anyone with experence in this area.

Thank you for your assistance.
