Hello, In the project we have done for a municipality, we have drawn flat reinforcement in two directions at the bottom and an addition on the supports for the slab flooring. However, the reporter says that the top additions cannot stay in the air, so that the crimped addition used in pleated floors should be discarded. I couldn't find it in a source, I would appreciate it if you could help with this. I wish everyone a good work. The flat ones in the pictures below are the crimped ones if the program output is requested from us.
