The overturning component of the hold-down force is calculated by
F = Vh/ L
where
V is the factored shear force on the wall segment,
h is the height of the shear wall plus the joist depth, as shown in O86 Figure 11.7. Refer also to wall heights at gable ends.
L is the length of the shear wall minus twice the hold down offset entered in the Hold-down settings, and the wall length minus 300 mm for anchorages, to comply with CSA O86 11.6.4.1.
