Comment:-
I think that you are using a code other than BS or the EUROCODE. For BS or EUROCODE, span/effective depth ratio =7 (not 10). Well, that is a code issue as such we may not have to deliberate on that.

Could you please indicate the span of the cantilever slab that you are using a thickness of 115mm to design? I believe that that should be a very short cantilever indeed as such will have nothing to do with the issue in discuss.
