Hello, I wonder if the Fs and F1 coefficients can be entered manually without defining a new spectrum. I would like to point out some of the things I encountered in the program... Column max purst. It remained 0.03 and became 0.04 in the new regulation. When we lower the Columns or Curtains from the upper level to the lower level, no sprouts are formed on the foundation. Likewise, no sprouts are formed in the columns that are on the beam and curtain. Good work...
