Hello friends, I interpreted the earthquake region selection of a region (abroad) with a 3.8 magnitude earthquake 40 years ago as the 3rd degree. I entered the floor type as Z3. building ground +4 floors. I have a design with 5 curtains on the ground floor and curtains around the stairs on normal floors. My question is, what are your suggestions about choosing the R coefficient?
 
Thank you for your answer. I interpreted it as a normal selection as it is a 3rd degree earthquake zone. When I re-examined the regulation, I saw that the right solution was R=7 and High ductility level. My solution was these principles.
 
According to the earthquake regulation; High ductility level should be selected for 1st and 2nd degree earthquake zones, but you can choose high ductility level for 3rd and 4th degree earthquake zones at your discretion.
 
While determining the ductility level of the building carrier system, the regulation imposes certain restrictions. such as building height or earthquake zone. However, the same regulation also says that we may not consider these restrictions. when you say we can ignore it, it will be when we use curtains. in this way, the regulation leaves the designer alone. The desired ductility can be selected in any earthquake zone. I recommend that you examine the 2.5.3 and 2.5.4 headings of the regulation.
