67 Shearwall STRONG-WALL SHEARWALL The building designer shall verify that these details are consistent with the complete load path requirements of the structure. 1. For plywood shear panel, add P to model name (e.g. SW24x8P), and multiply loads by 0.88. 2. For two-pour applications, use the SSTB34. 3. Recommended header moisture content is 19% or less at time of installation. 4. A single wall garage portal system consists of 1 wall with a header spanning over the top and connected as shown. 5. Recommended minimum 5/8"x12" mudsill anchor. 6. 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. 7. Portal walls may be installed with sheathing facing inside or outside. 8. Maximum shim height between Strong-Wall Portal Walls and header is ". Shims of greater thickness will result in load reductions. 9. See allowable vertical load table on page 64 for Strong-Wall maximum compression and tension capacities. 10.Capacities must be reduced as limited by anchor bolt capacities for installations on CMU.

Beam to support post and support post to foundation uplift connectors may be reduced where justified by calculations. 2. This detail reflects lateral load requirements of a Single and Double Wall Portal system. It is the designers responsibility to provide a complete load path for all loads in accordance with the governing codes. 3. System rating equals the sum of the Single and Double Wall Portal values. 4. Alternate Installation: A single piece header (no camber) may be substituted for the two headers shown. The design rating for this condition may then be evaluated as the sum of the individual wall (pier) ratings. Individual wall (pier) ratings for this condition may be taken as half of their Double Wall Portal values. 5. Longer header spans can be accommodated if larger headers are used such that equivalent stiffness is equal to or greater than that provided by the minimum header and maximum length indicated. 6. LTP4 and LSTA24 (design by others) are minimum requirements to achieve the allowable loads. CODES: See page 12 for Code Listing Key Chart. Detail 1 Single Wall Garage Portal 1.
