UNL PARAMETER BS5950

  1. Dear Experts,

I got a different UR result between assigning UNL and not assigning UNL and it give me a confusion which model is true. Hereby I attached separate model with UNL parameter and no UNL parameter. Which model is more accurate to design?

Thanks for your support.
