Long Term Factor from NDS 3.5.2 (Changes 29-33, 34)

The interpretation of NDS 3.5.2 has changed to accord better with the design code. Previously, you could choose whether to design for total deflection, and if you did, you would apply a factor to the dead load, which defaults to 1.5, corresponding to the long term creep factor in NDS 3.5.2. Now, the program always designs for long term deflection, and you choose whether to apply a creep factor, which defaults to 1.5 if it is included.

The input for this has been moved to the load input view, where related controls for load combinations for design criteria are also located. The terminology has changed to include the terms Kcr and creep, rather than just “total deflection”.
