Earthquake Regulation article 4.3.4.6

Mr. Muhammed, the explanation mentioned is wrong. If Mdev>0.75*M0 is not provided, the indicated system is A33. In other words, since your regulation curtain is not enough, it makes you buy smaller R and D and increases your earthquake strength. Normally, it only allows you to construct a columnar hollow block building only if DTS=3 or DTS=4. But even if there is only one curtain in your building, it allows you to solve in DTS=1, 2, 3 or 4 (A23, A24), it punishes you if Mdev>0.75*M0 is not provided and says follow the R, D and BYS rule in A33. . I hope it's clear this time.
 
Hello. I think that the most discussed items of this regulation for us are 4.3.2.4. and 4.3.4.6. it will be. 4.3.4.6. If the item does not meet the Mdev>=0.75 condition, it directs us to the A31 system. Mr. Mirza, the reason why the A31 is not active in your project is that you have exceeded the height limit. Because A31 BYS>=7 allows. It is a fact that if we are laying unidirectional gears in DTS=1 and DTS=2 earthquake zones, we have to meet the condition Mdev>=0.75. If this condition cannot be met, I recommend you to install cassette. But when we meet the condition of Mdev>=0.75, also article 4.3.2.4. I am one of those who think that there is no need to check. The regulation has already reduced the R coefficient to 5. I discussed this issue with the authorities at the IMO Bakırköy branch. They are also 4.3.2.4. They said there is no need to check. In addition, the mixed system solution is made in this way in the handbook of IMO.
 
In addition, 4.3.4.3 of the regulation. must be interpreted well. It is stated here that hollow floor slabs will be considered limited ductile if they do not contain curtains and can only be used in buildings with DTS=3 and DTS=4. What is meant by including curtains? Putting a 25*160 size curtain anywhere in our system? Or is it to meet the 0.75*M0 condition specified in 4.3.4.6? Undoubtedly, I believe that it is necessary to meet the 0.75*M0 condition. If this condition is not met, our system will be limited ductile.

Muhammed Bey, The explanation mentioned is incorrect. If Mdev>0.75*M0 is not provided, the indicated system is A33. That is, since your regulation curtain is not sufficient, it makes you take smaller R and D and increases your earthquake strength. Normally it only allows you to build a columnar hollow block building only if DTS=3 or DTS=4. But if your building has even one curtain, it allows you to make a solution in DTS=1, 2, 3 or 4 (A23, A24), if Mdev If >0.75*M0 is not provided, he punishes you and says follow the R, D and BYS rule in A33. I hope this time it is understood.

Erhan Bey, I understand exactly as you said. Nuray Hoca's explanation is problematic.
 
A33 contains frames with limited ductility and curtains with limited ductility level . 4.3.4.3. article states that hollow blocks can be mixed with high ductile curtains.
 
Mr. Erhan, I will make a correction to your comment. If we write A31 instead of
, the system indicated is A33

. In other words, R/D and BYS of A31 will be used. If you check the second paragraph of 4.3.4.6, you will agree. good work, best regards...

What we call the regulation is up to our comments, although it should be precise and clear, they cannot even explain the sentences they wrote with confidence, it is so obvious that we are an original regulation. It's just a show off, like many things happening in this country

Exactly, we're looking for a needle in a haystack when the items should be clear. Nothing is clear, it's a fiasco
 
I think the regulation is very good. We can say that he wanted a technical staff member who likes to analyze, not an engineer who believes in program outputs and is condemned to analysis outputs, but who sees analysis not as a result but as a source of inspiration that gives him ideas, who knows the limits and balances security and economy.
