frictional fixity

[Rubinsa]

Hi,
Is there a way to define a frictional fixity in opensees? I want to model a roller that is not completely free and follow coulomb friction law.

Thanks

You can use a zero length element with coulomb friction material.

Thank you! You mean zeroLengthContact2D ? or simple zeroLength with frictional material assigned to that?

[lestoter]

same for me!color by number

use zeroLength element of length zero with coulomb, friction material happy wheels
