question 1 there is no information about cassette flooring in the new regulation. Is the ductility level of cassette flooring limited or high and can dts 1 and dts 2 also be used without curtains? Question 2 In item A33, can the SDS FRAME + SDS SCREEN system be used in DTS 1.2? In the regulation, only dts 1,2 said that the ductile level limited frame cannot be used, I could not find any information about it.
 
Hello, First of all, please read the 4th part of the regulation again and carefully. Cassette is subject to the same rules as slab with floor joists. You can solve high, mixed or limited. Question 1: Can it be used fretless for DTS=1 or 2? Answer: When you look at Table 4.1, you will see that you need to use either the A11 or the A31 system for a curtainless structure. As long as BYS >=3, you can design it as A11 system. A31 system DTS=3 or 4 is allowed in limited systems. See: Item 4.3.4.3 Question 2: Can the A33 system be used for DTS= 1 or 2? Answer: A33 system can be used in buildings other than BKS=1, that is, DTS =1a, 2a, 3a or 4a. See: Article 4.3.4.1 a
 
Thank you very much, Mr. Erhan, I mean, the new regulation really creates a lot of question marks, such as puzzle items, which are always left open.
 
erhan bey, there is an expression in article 4.34.3 that systems with limited ductility level will only be used in dts 3 and dts 4, as if item A33 cannot be applied in dts 1,2, or am I wrong?

This is exactly what I'm talking about when I say read it in your mind! What do you understand by the sentence "carrier systems that meet all the earthquake effects with reinforced concrete frames with limited moment transferring ductility level"? Moreover, A31 is also mentioned in parentheses. Pay attention to what kind of system A33 is.
 
ductility level in the sentence will be classified as limited load-bearing systems and will only be used in buildings with DTS=3 and DTS=4. confused me. because A33 material enters carrier systems with limited ductility level
