Plausible Deformations at Time

I am calculating deformations at time 0 and at time infinite. The deformations at time infinite seem plausible. The deformations at time 0 seem significantly smaller and thus implausible. What can be the cause?

Answer:

Please check to see if the structure cracks due to the pure load. It is possible that the increase in deformations is caused mainly by creeping and shrinkage, which are not active at time 0. The nonlinear calculation considers the shrinkage as a strain load, which may cause additional stresses.
