The linear deflection analysis calculates with the stiffness of ideal cross-section (without crack influence) and without the rheological effects.
The nonlinear deflection analysis involves the construction stages, the stiffness of the cracked cross-section, influence of the creep and shrinkage in each construction stage.

The result from the nonlinear analysis is at the bottom of the picture and the values are almost doubled compared to the linear result at the top of the picture.
