frictional fixity

Post by Rubinsa » Tue Feb 28, 2023 1:30 pm

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?
