I am working through a reinforced running-bond masonry wall design for wing pressure coupled with a vertical load component and I am having trouble understanding one aspect of the MSJC codes.
In section 2.3.3.3.1, it specifies a width of compression area used in stress calculations. Is this the "b" term used when determining Axial, Shear, and Flexural Compression? If so, then you are not supposed to design the wall based on a 12" section?
If you design for the "b" term width, then I am guessing you would use the pressure over that width in determining your forces and/or moments?
If you design for 12", then I am assuming you have to ensure you use a proportionate area of steel reinforcing in that section?
To me, it seems as though these would result in the same stresses...one based on a larger section with larger loads and consequently larger area of steel...the other on a smaller section with smaller loads and a percentage of the reinforcment area.
Am I correct?

For in-plane flexure and shear of a partially grouted wall, you need to determine your effective width of the wall "b" based on the effective section properties.

For in-plane loading, the equations are similar, but b= wall thickness. b=full wall thickness if grouted solid, average wall thickness if partially grouted.

as b.

StructuralEIT, I see your responses everywhere on this board and you are usually spot on...how come your still an EIT?!
