66 Shearwall STRONG-WALL SHEARWALL The building designer shall verify that these details are consistent with the complete load path requirements of the structure. GARAGE PORTAL SYSTEMS 1. The height of the garage curb above the garage slab is critical for rough header opening on portal walls. 2. One 1/2" shim is provided with Garage Portal walls. 22" Garage Portal Model No. W (in) H (in) T (in) Number of Fasteners in Top of Wall Allow. Shear V Load (lb) for Portal System 5 Drift at Allow.

For plywood shear panel, add P to model name (e.g. SW24x8P), and multiply the table loads by 0.88. 2. For two-pour bolted applications, use the SSTB34. 3. Recommended header moisture content is 19% or less at time of installation. 4. A double wall garage portal system consists of 2 walls with a header spanning over the top and connected as shown. 5. SW16 and SW22 walls may be combined. The capacity of the combined system shall be the sum of the Single Wall Garage Portal capacities. 6. Recommended minimum 5/8"x12" mudsill anchor. 7. The minimum header sizes listed are the minimum required for lateral rigidity of the portal system. Larger headers may be required due to vertical loading. 8. Portal walls may be installed with sheathing facing inside or outside. 9. Maximum shim height between Strong-Wall Portal Walls and header is ". Shims of greater thickness will result in load reductions. 10. See allowable vertical load table on page 64 for Strong-Wall maximum compression and tension capacities. 11.Capacities must be reduced as limited by anchor bolt capacities for installations on CMU. DOUBLE WALL GARAGE PORTAL 4 16" Garage Portal Alternate Exterior Installation For easy electrical installation position wall with sheathing inside garage. Garage Portal systems provide increased lateral resistance over site-built shearwalls in locations where space is at a premium. Portal walls shall be installed with a minimum 12" nominal deep header for adequate shear nailing. Because the portal walls and header are tested as a system, the resulting portal frame offers superior engineered performance over site-built walls. CODES: See page 12 for Code Listing Key Chart.

NOTE FOR GARAGE PORTAL WALLS: Cripple walls over the garage header shall be designed by Engineer of Record. Drilling or cutting holes in Strong-Wall Shearwalls is not allowed except as shown in the Allowable Hole Chart attached to each wall.
