Slab Design for Concrete apron between walls

Slab Design for Concrete apron between walls

Slab Design for Concrete apron between walls

(OP)
I am designing a reinforced concrete spillway structure that will be configured with 4 50-foot wide bays.  Each bay will be separated by a wall, which will act as a retaining wall if one of the bays actually overtops and starts to spill.  

What is the best way to consider design of thickness for the 50-foot floor span between each wall?  Will there be much load transfer from the walls to the slab causing upward moments in the slab?  Is it best to use a different thickness for the floors near the walls to act essentially as footings to provide all the load transfer and shear thickness required?

Because the span is so long, it seems that by structurally separating them from the wall and wall footing with a construction joint will help them to be thinner.

Any other thoughts or ways to think about this?

4 BAYS @ 50' = 200' CONSIDER JOINTS ALSO.
WILL EACH BAY BE OPEN-ENDED? A 3 SIDED SHOEBOX WITH ONE END GONE?

I WOULD CHECK THE SLAB AREA AT THE WALL AS A CANTILEVERED RETAINING WALL TO DETERMINE ITS PROPERTIES, LENGTH, THICKNESS ETC.  THE AREAS OUTSIDE THAT REQUIRED FOR THE RETAINING WALL COULD HAVE A LESSER THICKNESS.

I HAVE ALSO DESIGNED SIMILAR TYPE WALLS USING AN ELASTIC BEAM ANALYSIS WITH GOOD RESULTS.

BEST, TINCAN
