Hi everyone,

Looking to get advise/comments on the following.

In the attached image, inside the green thick line is a 800mm slab and on the outside is a 300mm slab. The orange represents the moment capacity of a 800mm slab. As you can see some parts of the 300mm slab technically are required to be 800mm due to the moments 'spilling'. When I increase the extent of the 800mm slab to capture this, the moments 'run away' and the slab extent is required to get bigger and bigger. The question is, is there a way to justify the moments spilling and parts of the 300mm slab being over the moment capacity? Otherwise the extent of the slab gets excessive.
 
Although some FEM resources are beneficial for visualizing behavior - I consider them to be a secondary tool.

Can you provide us with some further context? Locations of columns above and columns below. Lengths between supports. Magnitude of loads.
 
I expect that you'll have to accept some degree of moment redistribution at the boundary. Mesh refinement might also help mitigate the impact.
