According to all design codes, this component is calculated as the product of the shear line design shear and wall height. It it is constant along a shear line in the case that shear is distributed according to wall capacity and the walls are all constructed from similar materials; otherwise forces can be different along the shear line.
Separate shear overturning components and separate combined holddown forces are generated for wind loads and seismic loads,in each direction, and for the rigid and flexible methods, so that eight different hold-down design cases are calculated.
Applied Shear vs Shear Capacity
A Design Setting permits you to specify which shear value to use, the induced shear v or the shear wall's capacity.
