Hello. In my attached project, there is a gap of about 7.5 meters between two columns, there is no problem by solving the hollow floor slab. ( 1/20 beam thickness turns out to be 40 cm ) The amount of deflection in the beams is not too high . This is the first time I'm solving such a wide opening. I would be glad if you tell me what mistakes and deficiencies you would recommend in the project, if any.

In my project, in the raft basic additional reinforcement tab, one of the design moments is 120 tm (60 cm2 reinforcement area is obtained Q30/10 It saves), what should I do to reduce it. I can't do adjacent ampatment.
 
Hi, Model all tiles as cassettes for Continuity. Continuities will be ignored when you use cassette and rib flooring together. Model as 1 tie beam for slabs exceeding 4 m. General rules about rib flooring are explained in the link below.

If the ribs are continuous in hollow blocks, 1/25 of the net opening can be taken as the slab thickness Sent via iPhone using Tapatalk
