Mr. coskun3561, First of all, I would like to comment on the system in general. If we install the structural system properly, the errors in details will become less important. 1- 70% of the horizontal load carries the curtains in the Y direction, but only 177 tons of the 361t floor shear The curtain takes P93. This is not balanced. Distribute the curtains more evenly in the Y direction. You can reduce P93. 2- 25/50 column A column size that can be used in 3-5-storey buildings. I use it in places that are very light even in 5-6-storey structures. Min 30/70 Use columns in a 10-storey building 3- 25/50 beams are too weak Don't use 25/60 beams below. Where necessary (you can use 30 beams in places where shear and torsion are high. 4- You can't get R=8 in a curtain wall structure, max. 7 Germans) Receiving R=7 means accepting a highly ductile structure and the structure must meet all of the high ductile requirements.If it doesn't meet even one, you should take the structure as normal ductile TDY 3.3, 3.4, 3.5, 3.6, but with 25 column in your structure You can't provide them with s, especially 3.5i. For this reason, first of all, do not use a column of less than 30. 5- Beam connections between D-Aj axes are weak. Add a beam connection to complete the Y-direction frames of the architecturally appropriate structure. 6- You can use partial hollow block, this is a method I use a lot, but in the main carrier frames, tilt the normal beams and their frames, only use hollow blocks where necessary. I would not recommend cork flooring at all, it is a structure with a high risk of brittle fracture and is dangerous. If you carry 75% of the horizontal load to the curtains (with a balanced distribution of curtains), your system will be relieved as there will be no excess load on the frames.
