Deflection on adjoining slabs

We have a problem where the deflections for adjoining slabs (i.e. two panels) are not maintaining continuity through their connection (i.e. one panel has relatively low deflections along the join and the other has excessive deflections).


We have removed the applied loads and remodelled the panels but to no effect.


Please find the link to the model (and screen print) for clarification.


What has caused this error and what is the solution?

The equivalent stiffness method is the simplified approach based on average stiffness reduction factor which is calculated for each of the panels separately. Try to run the verification of the deflection using  the stiffness update method for the selection of the panels from the screen shoot.
