Earthquake load stiffness reduction factor

have a nice day; I couldn't correct the B error in a column with dimensions, then I reduced the earthquake load stiffness of the column from 1 to 0.8, and when I reduced the vertical load stiffness of a beam to which it is attached from 1 to 0.8, the B error was corrected. Does it comply with earthquake regulations?
 
Re: earthquake load stiffness reduction factor! Hello, According to the Article 3.2.3 of the Earthquake Code 2007, you cannot reduce the stiffness of sections, except for beams and tie beams embedded in the shear walls in their own plane.
 
I don't understand where you are looking. See the file below. What you are looking at is the draft text of the new regulation that is planned to be published. As far as I know, it hasn't come into effect yet. Let us know if it did.
 
The new (you're looking at) regulation mentions effective section stiffness. You can refer to the article 4.5.4 for the shear walls, to the article 4.5.8 for the effective section stiffness
 
I hurriedly looked at the draft on gov.tr and couldn't see it there, I understood, thanks, but when we reduce the stiffness reduction factor in the column or beam, where can we examine it in the ide report?

Right click on the perspective screen-- You can see it on the perspective screen as >Analysis System Display Options -->Reinforced Concrete Design-->Data-->Rigidity Reductions Stiffness reduction values are not available in the report.
