Hi everyone, I have this nonlinear column with a harmonic load on the top and is working using a linear analysis. However, I am not sure why the nonlinear analysis is not working good. It seems that the system cross the elastic limit but after a couple of cycles come back to the linear range. # colu...

Dr. Scott,
Thank you very much. Could you please tell me where could I find an example with this type of load ?

Hi everyone,
I am try to put load as an harmonic signal applied on the top of the structure. At the moment the information available is focus on ground motion.
