Perforated Shear Wall Design

Perforated shear walls require hold-downs at the wall ends only, but a shear capacity reduction factor Co based on the size of the openings is applied. So although perforated walls have a lower shear capacity than segmented walls, they have the advantage of requiring fewer hold-downs.

An adjustment for narrow segments within the wall is also applied to the capacity, and the Co factor and narrow segment adjustment are also applied in creating the uplift anchorage force t and lateral anchorage shear force, and in calculating the Deflection of Perforated Shear Walls, Perforated Shear Wall Hold-down Forces and Drag Strut Forces in Perforated Walls.
