Why does the static part of the solution ignors damage when adding creep behavior to R.c material?

      The static results becomes linear ignoring damage in concrete how ever the model without creep step gives verified resultsn

      Please reply with a far more detailed description of your model, the loads, supports, materials and results. What you expected and what you got.n
