I have a question. After we choose the R coefficient, the program can change the coefficient we chose. Can we prevent this? Can I use the coefficient I got. I would be very happy if friends who know help me.

Hi, the R coefficient is automatically reduced by multiplying the value of ncmin between 0.60 and 0.80 and the value of 1.25ncmim depending on the B1 irregularity, according to TDY item 2.3.2.3. In order for this not to happen, the value of ncmin must be greater than 0.8. , ncmin value can be large, it is related to the ratio of the sum of the shear area between the floors and the vertical carrier effective shear area.For details, see 2.3.2.3.
