Required reinf on top slab edge of simply supported slab?

Afternoon All,

I have a bit of a strange result with the following slab. The slab has linear pinned edges for full perimeter, and just two vertical downward UDL's.


Apparently even with a fully pinned perimeter the required reinforcement is fairly high on the top slab surface at some angles corners. Please refer to screenshot and RTD file attached. Is this a glitch from a coarse mesh? Feedback from any experts is appreciated!

This is the minimal reinforcement. You can lower it setting the minimal reinforcement to none in the reinforcement label assigned to the panel. You can also decide to use W&A method for reinforcement calculations instead of the analytical one. Mind that you will have some top reinforcement in the corners anyway due to Mxy moment.
