If deflection-based shear distribution to segments is selected in the Design Settings, the force on the force-transfer shear wall in a shear line is determined by equalizing the deflection of the entire wall with other force-transfer walls and with other non-force-transfer shear resisting elements on the line. In other words, the segment-averaging process within a force force-transfer wall is incorporated into the iterations that equalize shear wall deflections on the entire line.
The distribution of the force to sheathing on either side of each segment in a two-sided shear wall is determined by equalizing the nail slip plus shear components of the deflection equation, as it is for all other wall types.
