1) Yes, thanks to Peter in the previous discussion, I was able to generate the cracking of the beam. But I realized that I was not able to identify the ultimate load because the load is increasing together with the deflection. Theoretically, the load will start to decrease after reach the failure mode as shown in below figure.
2) Thank you for your suggestion using the eigenvalue analysis. If not mistaken, in this analysis, a gradually increasing load is applied to seek the load level at which the structure becomes unstable. May I know how to identify the unstable structure?
Thank you in advance and very sorry for the inconvenience.

I'm faced with the same situation. I applied my load using in load steps and using the program controlled option. With the load steps option the graph is not what I'm expecting and with the program controlled option, I'm getting a linear elastic curve.
Did you get a solution to this problem?

I’m struggling with the same problem. I’m m a RC concrete slab. I applied displacement instead of force. But the load keep increasing! (No negative slope). I’m wondering if you figured out how to solve this problem?
Kind regards Emad
