What is the best software for truss buckling analysis?

[Enthalpy]

Hello everybody!

From time to time, I'd like to compute the minimum force that buckles a truss, and hand computations get quickly too complicated.

So: could you recommend me a piece of software for that?

What I need:
- Quickly learned and installed, for Windows, free of nearly (I know that's incompatible)
- Something like 30 nodes and 60 beams
- Input as a text file would be just fine

Thank you!

I just recently downloaded "Framework" from http://members.ziggo.nl/wolsink/
I haven't even installed it, so I can't give any opinion on its usefulness, but the feature set is impressive, and it's free.
