Why do linear and nonlinear long-term cracked-analysis results differ?

...

  • Use the Draw > Draw Slab Rebar option to model the reinforcement as required. Use the User-Specified Rebar option to analyze slab deflection.

What slab reinforcement is used in nonlinear analysis?

Answer: Cracked analysis uses rebars as defined in reinforcing source via run>cracking analysis options. One of the following three reinforcement sources may be selected:

a) User specified, user needs to add rebar in both tension and compression regions as applicable to the entire slab as program will not use design reinforcement along with user specified reinforcement.

b) FEM based, design rebars will be used as reinforcing source

c) Quick top and bottom tension reinforcing is self-explanatory.

Minimum reinforcing ratio used for cracking analysis applies regardless of the option selected for reinforcement source. The program uses the largest ratio between minimum and any of the options selected above a), b) or c). 

To what demand does SAFE design the reinforcement?
