5.6.5 Narrow Shear Walls
Narrow wood shear walls with an aspect ratio greater than 2 to 1 do not resist forces developed in the building.
For conforming buildings, the evaluator may consider this condition as mitigated, and no calculations are necessary. The deficiency is in the strength of the narrow walls. Determine the shear capacity of the wall and related overturning demand. This shear capacity and related overturning must be transferred to the foundation within allowable stresses.
