Re: Stairs Intermediate Shelf Supportless Beam and Floor Level Line Hello Mr. Levent, first of all thank you for your feedback. When I went to this old building place, there is no main beam in the empty parts (like on the floor level), I checked the cantilever stud beam to the column and I couldn't see it (coring, stripping was already done, I broke it a little for this place, but I didn't want to cause much damage) He started the cm tooth from scratch and was already supported on the 20/50 deep beam, where the hollow main beam on the stair landing is connected to the floor. There are no details for the staircase part in the project. For the beams, no studs or other defined beams are shown in the plan. Is the only solution at this stage to throw stud beams there as you stated? (Even if I make a closed system as you indicated in the attached picture and discard these beams, when I want to delete the empty beams at the top, they want to detect and delete them defined with the lower ones)
