Turkish In the earthquake zone in the 4th creek, the r coefficient and the ductility level should be chosen in the building where the basement floor has a partial basement shear. Thanks in advance for your help, I am attaching the project. Also, the number of rigid basement floors was taken as -2. Is it correct?

R coefficient and choice of ductility

The R coefficient is directly related to whether there is a curtain or not in the project. The rigid basement floor number is also related to the perimeter curtains that do not continue on all floors. The only way to say anything in detail about both is to add the project. Otherwise, nothing is said as it is. If you read the regulation on the R coefficient, it will be very helpful for you to decide. You can submit your project via an upload site. Good work.
As Nedim said, it is not possible to answer your question as it is. Because the answer to the question lies in your carrier system. If your curtains are sufficient and if they meet the alpha s condition, we can say that if your curtains are high ductile and if your frame is normal ductile, you can get r= 6, and you can not make strong column and joint shear safety controls. If you do not have a shear wall, you will get r=8, your earthquake load affecting your system will decrease, but the ductility controls we mentioned come into play. If you do not have a shear because you are in the 4th degree earthquake zone, you can take r=4 and solve for a normal system with ductility level, provided that the building importance factor is <1.4 and Hn<25m(floor system; Hn<13m if it is geared, cassette and beamless). So as you can see, we have plenty of R. You can choose according to your system. anyway the program will guide you about the selection of the R coefficient. Mr. Nedim, please correct me if I am wrong... good work... KEMAL YALVAÇ
I mentioned it briefly, you can add some more information. You supported the issue. Thank you. Our regulation is written in a way that is difficult to understand. However, it becomes clear after reading it a few times. I advise all young friends to keep the regulation on their desks. Of course, it is not cute enough to read like a novel, but if we open it and look at every issue that comes to our mind, more things will remain in our minds.

So you can understand that we can choose according to your R abundant system. The program will guide you about the selection of the R coefficient anyway. Mr. Nedim, I'm wrong. If there is, please correct it... good work... KEMAL YALVAÇ
