A clarification in SDPWS 2015 Commentary C4.3.3.4 of the "same materials and construction" requirement in 4.3.3.3 interprets it to mean that classes of materials such as wood structural panels, gypsum wallboard, fiberboard must be the same, but details such as the sheathing thickness and nailing patterns do not have to be identical. A Design Setting allows you to force all walls to have identical materials, otherwise construction details can be different on each wall. If the design setting is set, if you change a material item on one of the shear walls, the same property changes on all the rest.
Non-shear walls:
If you specify that all walls on a line must have the same materials, the non-shear walls on the same shear line and on the same building level must have the same materials as other non-shear walls, but they can be different from the shear walls on the shear line.
Different shear strengths and rigidity:
Regardless of the identical materials and construction setting, shear walls along a shear line can be of different types (perforated or segmented) and therefore have different perforation factors so they have different shear capacities. DIfferent shear capacities can also arise due to segment aspect ratio factors .
Segmented shear wall segments, or entire perforated or force-transfer walls will have different rigidities if deflection-based distribution is selected in the Design Settings. Even for capacity-based distribution, rigidities can differ if the capacities do for the above mentioned reasons.
