Hi dear Vesna

Hi,
I want to do nonlinear time history analysis in Opensees and i need period time history as a result for my structure model .
If opensees give us period time history as an output ? In other word, how can i get period time history as an output in opensees during linear and nonlinear time history analysis.
Thank u so much
