Construction deflection


When working with construction steps and activating one span (deformed) after a previous one has been active, there is a jump in the deflections even with "Initial Displacement for C.S." is active. How to avoid the jumps in deflection values in the same girder?  


The jump in deflections in same girder can be avoided by viewing the results by checking on "stage/step real displacements" option as described below with help of an example.
I modeled the 2 span girder activated in 2 construction stages as shown below.

Construction stage analysis was performed where only dead load due to self weight was applied.

After analyzing the model, displacement contour due self-weight for construction stage 2 is observed . The jump in result is observed.

But now, when the results for displacement contour are viewed by checking on the Stage/Step real Disp. option, the jump disappears as shown below
