Hi Naik,


  Softening behavior refers to the damage that occurs in the stress-strain behavior of a concrete material. Please go through this article for some additional description.


  Now, when you have this behavior included you would see a load vs deflection as discussed in this paper, which helps you determine the ultimate load vs deflection.


  Hope this helps.


Regards,


Sandeep
