Analysis Buckling

 

Can you help me, I have trouble solving buckling analysis, can you help me to provide references / examples of solving buckling analysis steps on a space truss structure.
thanks

You may want to start here, http://people.wallawalla.edu/~louie.yaw/Co-rotational_docs/2Dcorot_truss...

see references at the end.

I want to implement a 3d corotational truss program in the future, I just haven't had time yet.  I have derived the formulas for a 3d corotational truss program, but I have not implemented it yet.  I followed the basic approach of Crisfield, which is different in some respects to the derivation shown for the 2d case in the pdf file link given above.

You may also want to look at http://www.colorado.edu/engineering/CAS/courses.d/NFEM.d/Home.html

good luck

Louie

Do you have examples in the manual solution for buckling analysis of space truss manually

A 3D corotational truss analysis formulation is available at the following location:

I hope this is helpful to those who may be interested.
