5. The shear walls must have a maximum height-to-width aspect ratio of 2:1. 6. ZIP System R-sheathing used as the lateral resistance system in seismic zones D 0 , D 1 , D 2 and E should be designed in accordance to ER-482. 7. This panel and fastening configuration is applicable to the prescriptive bracing requirements under the 2021 IRC.
For SI: Inch = 25.4mm; 1 pound per foot (ppf) = 14.59 N/m. * Structural design values can be found in ESR-3373. 1. Prescriptive bracing requirements under the 2021 IRC. 2. Not approved for use as prescriptive wall bracing where wind design is required by R301.2.1.1. 3. Engineered shear wall requirements with Douglas Fir-Larch Framing under the 2021 IBC. 4. Fasteners must be common nails or equivalent, or staples, of a type generally used to attach wood sheathing.
