A wall can be defined as a shear wall or a non-shearwall using the Hold-down configuration drop-down in the Wall and Shear Line Input form. These types refer to the design methodology employed and do not reflect physical characteristics of the wall itself aside from the placement of hold-downs .
For walls defined as shear walls, refer to hold-downs and anchorages for a description of the choices regarding configuration of hold-downs and/or anchorages along the wall, and their implications regarding shear wall design.
Non-shear walls are a portion of the shear line that is not intended to resist shear load. The program ignores non-shear walls when distributing shear loads to the shear lines. Exterior non-shear walls are, however, designed for suction loads. If all walls on a shear line are non-shear walls, then no shear loads are distributed to that shear line. Vertical loads that bear on non-shear walls are ignored, as they do not enter into holddown calculations. A drag strut is required across non-shear walls.
Non-shear walls appear hollow on the screen. All shear walls appear solid on the screen, regardless of hold-down setting.
