I have conducted buckling analysis in order to obtain the critical load and the initial imperfection shape for the next step, which is Static, Riks. After the analysis, as a result i get that the Load Proportionality Factor shows that the maximum load is greater than critical load from buckling step. I am modeling a beam (channel tube) and i am using shell elements. Can anybody help me with this?

Why is my LPF in Riks method greater than the critical load factor in Buckling analysis?
