Converge problem

[arash1985us]

Dear Dr.Silvia:
I did a pushover analysis on a 2D concrete frame.At the end of analysis the following warnings were emerged,but it is written that my analysis is done.What is my problem?What should I change?I used nonlinear beam-column with fiber section.Thanks dear Dr.Silvia.
Regards

the convergence script has worked, right?

Dear Dr. Silvia:
I doubled the fiber numbers from 20 to 40 and also increased displacement increment.Now it works without any convergence problems.Thank you so much
