The OpenSees Community

I tried building an earlier version of Opensees 10 times but failed. I was referring to http://nees.org/resources/2697/download ... co_Kim.pdf

I'll wait for the OpenFresco v2.7. Hope it releases soon.

Thanks for your quick reply Vesna. I'll wait for the new OpenFresco version.
I have no idea how to do it, but I'll try to build the earlier version in the mean time.

I am trying to use OpenFresco with Opensees to run Hybrid simulation examples, but as it turns out, the current version of OpenSees(v2.3.2) is not compatible with the current version of OpenFresco(v2.6) .
Is there any way to download any older version of OpenSees that is compatible with current version of OpenFresco?
Looking forward to a reply.
Thanks.

Thanks for the reply Vesna!

I have been trying to model a single friction pendulum bearing element applied at the base of a simple frame ( inverted U) . Compared to fixed, I am getting larger displacements and much smaller member forces, which I think make sense. I have a doubt though. On this webpage for FPS:

http://opensees.berkeley.edu/wiki/index ... ng_Element

What is the member for which we need to define these:

-P $matTag tag associated with previously-defined UniaxialMaterial in axial direction
-T $matTag tag associated with previously-defined UniaxialMaterial in torsional direction

Is this for the material of the FPS? or the frame member? Wonder why it's required when it already asks to define a friction model (I used coulomb) for the FPS.

Here is the code:

Hello,
I am trying to get the force deformation behavior of an inelastic material to get a bilinear curve. I am essentially trying to get this curve http://opensees.berkeley.edu/wiki/index ... 1_Material

I have been trying but I various errors like ForceBeamColumn2d..failed to get compatible forces and deformations and also convergence and integrator issues. This is what I am doing:

wipe;

Can someone tell me whats wrong with this? I tried changing the algorithm type etc. It doesn't run. I'd appreciate any help.
Thanks

I can't download buildingtcl.....the download page does'nt open. Is there any other way to download it?
