Hello,
I'm modelling simply supported shell element I-beam.
In my previous analysis I have used *IMPERFECTION command with results of linear buckling analysis(eigenvector). The result of this type of analysis was distorsional buckling(torsion and translation of my I-beam cross-section).
Now I need to use simplified approach. As the imperfection I want to use only bow shape of my beam with translation WITHOUT torsion of my cross-section with magnitude L/1000.
How to include this type of imperfections?
Thank You!
