I need to lay slabs on the foundation surrounded by floodplains and on the earth fill in between, but I could not find how to define it, but I think it would be wrong to define it as normal slab, because there will be no deflection problem like normal slab because it is full and there will not be a maximum moment at the midpoint of the slab. In practice, the wicker reinforcement fi8/30 or even fi8/40 is sufficient on the filling, but when I throw it in the program, the pile comes out and the reinforcement comes out too much. Is there anyone have an idea?
