A problem discovered in using Autodesk force effect to analyze the tru

  1. Sep 11, 2013 #1
    The Fink truss is my model. In analyzing this structure, autodesk doesn't give me the desired result. Look at point F, it doesn't reach equilibrium. I don't know why, but shall we continue to use this app in analyzing truss structures?

    It's kind of hard to follow your problem, since you jump right into the middle of it.

    There are free truss analyzers which can be downloaded off the net. I would check you truss with one of these.
    This is a pretty good package: http://www.grapesoftware.mb.ca/

    Thanks for your advice. Just by lookijg at point F, it doesnt reach equilibrium. But maybe I am wrong, so I wanna verify it
