Stiffness matrix

[ansysfreak]

Hi,

I have a question about the stiffness matrix?

I am trying to model a beam, and this beam is fixed supported,so this gives a rotation angle of zero. But nou I want to model an elastic fixed rupport, so the rotation angle isn't zero.

Where and how is this definied in the stiffness matrix, or how solve this problem?

Hi,

you can use the Combin7 element as a revolute joint whith defined stifness.
