Can the R coefficient be taken with fault?

[Medeniyetmuhendisi]

Due to the curtain shear force, alpha s is greater than 0.75. According to TDY 2.5.1 it says that R = 10 - 4*alpha is calculated as s. My alpha s 0.78 R coefficient is 6.88. Can I get R 6.88 in analysis? Or should I get 6.

Re: CAN I GET THE R COEFFICIENT AS DIFFERENT? Can I also get different R coefficients in the X and Y directions, with alpha s greater than 0.75 only in the Y direction?

Alpha s is greater than 0.75 due to the curtain shear force. It says R = 10 - 4*alpha s according to TDY 2.5.1. Alpha s is 0.78 R coefficient is 6, It turns out 88. In the analysis, can I take R as 6.88? Or should I take 6.

Hello, the coefficient of R can be taken as 6.88. It can also be taken as R=6 (In this case, more earthquake force will be applied to the structure.)

Can I get different R coefficients in X and Y directions with alpha s greater than 0.75 only in Y direction?

According to TDY 2007 article 2.5.1.3, different R coefficients can be used in two directions. Good work

Thank you very much for your information.
