Shearwalls determines the axial collector forces that accumulate across openings, non-shearwalls, or gaps in a shear line that must to be resisted by drag strut elements. Shearwalls calculates these forces but does not specify the resisting elements; it is the responsibility of the designer to design these elements and connections within them, such as occur at splices.
The double top plate of a wall is typically used as the drag strut element so drag strut forces are shown as an arrow emanating from a small circle just below the top of the wall in Elevation view. Arrows in the direction of the shear line force represent tension forces, arrows opposed to that direction show compression forces.
Collector forces are not visible in Plan View.
These forces are listed in the Collector Forces table of the Design Results. Negative numbers represent compression forces; positive numbers are tension forces.
