Documentation on FlatSlider(friction) & Elastomeric Bear

filipov1 · Post by **filipov1** » Tue Mar 02, 2010 2:48 pm

I have been trying to use the new OpenSees 2.2.0 element models:
1 FlatSlider2D and 3D - (particularly interested in the different friction models)
2 ElastomericBearing
3 FrictionPendelum

So far I have been using the source code as reference, but I have not been able to obtain realistic behavior/results from these elements. Does anyone know if there is any documentation available on how these models work and what the basic assumptions behind the models are?

Thanks in advance

i have been bugging the author almost daily for his documentation.

occumnaponi,
Thanks for your reply, I have looked at the documentation on the wiki that was uploaded some time ago, and it is quite comprehensive of the bearing behaviors and use in OpenSees. I have also worked on creating my own bearing element models and I am now using these, as I get more reasonable and appropriate results.
Thanks,
EF

how about contributing your models to the source code.

Yes, I am certainly planning to contribute these models to the source code. I am working on a paper with their formulation and will try to get bug free versions of these bearing element models later this year.
Thanks,
EF
