IN THE BUILDING WITH R COEFFICIENT 7, R COEFFICIENT 6.57 IS SELECTED ACCORDING TO THE SYSTEM BY THE PROGRAM, BUT I EXPLAIN THIS TO MY FRIENDS IN THE MUNICIPALITY BUT THEY ARE NOT CONVINCED HOW CAN I EXPLAIN IT?
Re: The program chooses the R Coefficient as 6.57, but I enter 7 When you read and understand tdy 2007 item 2.5.2.1 and item 2.5.2.2, you will find the reason for choosing it.
According to the earthquake regulations, the coefficient of 7 you entered has been reduced by 1.25cmmin. In the screenshot you added, ncmin=0.75, the R coefficient you entered is 7. R=7*1.25*0.75=6.57, which was chosen accordingly.
