Hi,
I'm at my first non-linear analysis with Robot and I feel a bit lost. I've watched P-Delta Analysis tutorial here http://www.robotoffice.com/rsa/ but didn't help much.
Just for starting off, I'm trying to compute the non-linear collapse factor for a column. I've then set up a model of a column slightly non-vertical (see the file attached) in order to let the non-linearity kick off. Then I've set up a P-Delta analysis imposing, among the "Additoinal criterions to stop analysis", a huge load factor so that the analysis runs until divergence.
From the result diagrams I see the column has buckled, but I cannot find in any way what I'm looking for:
- collapse factor;
- load-deflection diagram.
Could you please help me to find them out.
Thank you very much,
Davide
