First of all, thank you, I solved the same project in the same way before, no problem. I'm adding it as well.."YasinTezel":27a66m2v" said:Hi, In your project, all beams on the roof floor were leveled and low slab was made. Therefore, slab analyzes cannot be performed on the attic floor. My suggestion is to define +38 elevation for low slabs and bring them to the upper level of the beam. When you analyze again, reinforcement calculations can be made and You can take a drawing. I take this problem in our notes.
