SDPWS 4.3.5.5 limits walls in the same shear line to be composed of the same "materials". This is explained in C4.3.5.5 to mean walls with the same "sheathed wood frame shear wall systems".
The sheathing systems are as follows:
According to C4.3.5.5 wall still has the same shear wall system if there are different sheathing thickness, fastener sizes or spacing on different walls on the line, if some walls are blocked and some are unblocked, if the walls are of different types (segmented, perforated, OSB). The same reasoning would allow OSB sheathing on the same wall line as plywood sheathing, and discussions with AWC confirmed that it is acceptable to have some walls with wood structural panels on one side and gypsum wallboard on the other, and others with both sides WSP or WSP on one side and nothing on the other.
Accordingly, Shearwalls enforces 4.3.5.5 by ensuring all walls on the line have the same primary sheathing system, but allowing any other variations. If you change a wall on a line such that it has a different system than the other walls on the line, all walls on the line will change to the material selected.
Other changes will apply only to the selected wall, unless "Design in Group" is selected, and the change will apply to all walls in the structure with the same Standard Wall with "Design in Group" selected, as described in Standard Walls. As described in that topic, if you change a wall to have a different material type, and that wall or other walls on the line are part of a Standard Wall group with "Design in Group" selected, the change can reverberate through the structure recursively with walls on many different lines changing in an unpredictable way.
If you inadvertently change a standard wall group on your line by changing the material type of one of the walls, just revert your change using Undo. It will also revert any changes to other walls in the structure that came about because of your change.
Refer to Force Distribution within Shear Line and Force Distribution to Equalize Deflections about the required distribution of forces and deflections within a shear line from 4.3.5.5.1, and to Aspect Ratio Limits and Factors for the affect on shear capacity of narrow segments of the choice of shear distribution methods, given in the Exceptions in 4.3.5.5.1.
