Why does the deformation at time infinite differ from the deformation calculated in time?

Overview of the differences

The deformation at time infinite	The deformation over time
The result of this calculation is on deformation at time t = ∞.	The result of this calculation is the deformation at different times and at time t = ∞.
The cracked stiffness is determined using a SLS RC enveloppe.	The cracked stiffness is determined using the combinations imposed by the user. Usually you pick a SLS QP for dead loads and an SLS RC for variable loads).
Non-linearities (no tension at top walls, support that cannot bear tension, …) are taken into account	Non-linearities are neglected.
It is suppost that all loads cause creep.	It is supposed that all permanent loads (self weight and dead loads) + the quasi permanent part of the variable loads cause creep.

The deformation at time t = ∞ calculated with , is usally larger then the deformation at time t = ∞calcualted with .

How to obtain approximately the same result for both

The settings for this  calculation cannot be changed by the user, so will change the setting of this  calculation so the results approach those of this calculation.

1. Remove all non-linearities from the model.
2. Select SLS RC 1 as the combination for cracking for all load groups .
3. Add an additional combination in to in which all loads cause creep.
