For segmented shear walls, each wall segment between openings or between an opening and the end of the wall is considered a separate shear wall, and where an SDPWS provision refers to a "shear wall", it is applied to the wall segment. Narrow shear wall segments are subject to capacity adjustments given in 4.3.3.2 for deflection-based force distribution and 4.3.5.5.1 for capacity-based distribution.
When designing for unknown materials, the program uses the critical segment on the line in terms of force on the segment vs. segment capacity. The materials are then applied to all segments on the wall.
