Software for Truss Buckling?

  1. Nov 11, 2011 #1
    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.
