RC Continuity slabs

[benholland82]

Hi all, I am designing a two span simply support bridge deck... over the pier the will be a RC continuity slab (see link below). My question is how do I model the slab in by grillage? I have tried to model the flexural stiffness of the continuity slab as spring rotation supports within the main deck grillage but not having much luck. Does anyone have any good ideas or done something like this before?

Any help would be much appreciated.

Thanks, Ben
