the cheaper option to mitigate excess deflections in the right side of the slab might be to extend a continuous beam from the row of columns or to place a column under the stressed region, however architectural plans might prohibit that, forcing the less efficient option of either increasing tension reinforcement or thickening the slab, is what id think
Structurally this is a great option, unfortunately this isn't usually a good one as this beam will typically have to pass through the window line which will mess up the look of the building. Normally this kind of situation will happen on a typical floor and forming a beam on every floor to deal with a long cantilever isn't efficient in reality nor does it look good. The most efficient way is to convince the architect to decrease the cantilever length from the get go. If it isn't a possibility locally thickening the slab in that bay is a possibility, but again it comes at the cost of changing the window detail where the slab is thicker. It's not a big deal in terms of forming, it's mainly a pain architecturally to play with slab thicknesses on typical residential floors near windows. If this isn't a typical floor though and it's a one off solution it could be an option for sure. Good comment!
it was very nice to see how you can change the geometry of the slab and get an almost real time response to the new deflections, with a 'topographic map' of the displacements across the entire slab. do you know of any free sotware that is easy-ish to learn ?
Good comment...this is a useful function of SAFE IMO to size raft or mat footings in order to achieve relatively even pressure and settlement distributions. Resize and iterate manually....especially when the geometry is complicated. I am not aware of free software that is easy to learn no. SAFE isn't my favorite program and it gives funny values sometimes but it has its uses, this is one of them.

thank you, will have a look this evening when im relaxing.
Thanks Sage for the comment, you're the man! Hope you enjoy!

Which codes did you follow for this video?
Is there any way to show the flexural stresses in the slab? Thank you
