Do we make a negative change when we make a reduction by interfering with the Stiffness Reduction factors other than the program's automatic control on the beams connected to the shear wall or from the shear to the column on the model? How will the general behavior of the beam and the structure be affected? Also, if we make this reduction under both earthquake and vertical loads, we will be entering wrong data. I couldn't find any clear information on this topic in the forum.
