Fault of laying hollow on the balcony (rib)

[TheBEaST]

Hello everyone, take it easy. I just want to lay the balcony with hollow blocks, but in the geometry control (the console flooring cannot be designed as a single rib or cassette flooring), I get the error. When I make the flooring behind the balcony ribbed, there is no problem. but I just want to make the balcony hollow floor tiles. How can we fix this error, because I have seen many buildings that only have balconies or closed tops on the ground floor. thanks

Thank you, but as it is written in the link, we need to put reinforcement on the top because it carries a negative moment, but the program sees it as a simple support, we need to fix it in the drawings, is it true?

Even if the program solves the system in balance, it is a single console in terms of reinforcement the rib does not work statically.You have to reinforce it like beams.In practice, butt beams are made at the end of the ribs.You can also surround the end of the cantilevers with slanted beams or rotate the rib directions so that they are continuous with the inner ribs.
