Hold-down Force Components

The holddown force may consist of these components -

• the factored overturning moment due to the shear force in the adjacent full height segment;
• the resisting dead load component that is carried at that location;
• the wind uplift force that is applied to the building element at that location.

These components are combined by multiplying the dead load component by its load combination factor in the Design Settings before subtracting it from the shear overturning component. For wind forces, the wind uplift component is then added to create the combined hold-down force.

Only the combined force is displayed in plan view. Either the combined force or the separate components can be displayed in elevation view. The Design Results show the components and the combined force.
