Anchorage Deflection
If anchorages are used instead of hold-downs, the equation for vertical displacement from O86 11.7.1.2
where
- dF is the nail diameter
- Km is the service creep factor from O86 table A.23 for short-term loads, which is non-unity only for wet fabrication conditions
- v is the unit shear force in the wall segment
- Hs is the wall height
- Pij is dead load counteracting force at the hold-down location
- Sn is nail spacing
- Ls is
- nu is lateral nail resistance per nail from O86 12.9.3.
Linearization
If you have chosen to use the linearized 3-term equation, this equation is linearized in a similar fashion as for combined shear and nail slip:
where vcap is defined in Combined Shear and Nail Slip Deflection.
