The bearing plates are available from Simpson Strong-Tie and must be ordered separately.
4.0 DESIGN AND INSTALLATION 4.1 Design: 4.1.1 General: The tabulated allowable stress design (ASD) in-plane shear values provided in Tables 2 and 3 for standard and portal applications respectively, apply to WSW panels supported directly on normal weight concrete foundations with minimum specified compressive strengths as listed in the applicable table. In-plane ASD shear values for two-story stacked Strong-Wall wood shear panels are provided in Table 4 of this report. Maximum ASD in-plane shear values for Standard and Portal Frame System Strong-Wall SB panels are provided in Tables A1 and A3, respectively; and in-plane shear values for various concrete strengths and support conditions for Standard and Portal Frame System Strong-Wall SB applications are provided in Tables A2 and A4, respectively. ASD in-plane shear values for Stacked Strong-Wall SB panels are shown in Tables A5 and A6. A supplemental concrete bearing plate as described in Section 3.2.2.14 of this report must be specified under each hold-down when required by Tables A2, A4, and A6 of this report. Concrete must be normalweight with minimum specified compressive strength, f′c, of 2,500 psi (17.2 MPa) or as required in accordance with the applicable code, or as noted in the footnotes to the tables in this report. The top-of-panel drifts noted in Tables 2 through 4 and Tables A1 through A5 correspond to the tabulated ASD in-plane shear loads.
The tabulated ASD out-of-plane lateral strength values are provided in Table 5 for the WSW panels and Table A7 for SWSB panels. The ASD axial strength values of the WSW panels supported on normal weight concrete foundations are noted in Table 6 of this report. The maximum secondary bending moment, shear, and axial forces induced in the beam/header member in Portal Frame System SWSB applications are shown in Table A8.
Allowable ASD in-plane shear values provided in Tables 2 through 4 and Tables A1 through A6 of this report are applicable to both ASD basic load combinations in IBC Section 1605.3.1 and the alternative basic load combinations in IBC Section 1605.3.2. Strong-Wall panels may be used as components within a seismic-force-resisting system consisting of light-framed load-bearing or non-load-bearing wood walls with wood structural panels, provided the following seismic design coefficients and factors are used in design:
PARAMETER IBC
Response Modification Coefficient R = 6½
System Overstrength Factor Ω0 = 31
Deflection Amplification Factor Cd = 4 1Where Strong-Wall panels are installed in structures with flexible diaphragms, as determined in accordance with Section 12.3.1 of ASCE/SEI 7, the tabulated value of Ω0 may be reduced in accordance with Footnote g, Table 12.2-1 of ASCE/SEI 7.
Analysis and design of structures incorporating Strong-Wall panels must comply with the applicable code,
including IBC Section 1604.4. Where Strong-Wall panels of the same height but different widths are placed in a wall and/or combined with other shear-resisting elements, the applied loads must be proportioned based on relative lateral stiffness of the vertical resisting elements in accordance with ASCE/SEI 7 Section 12.8.4. Any combination with other lateral-force-resisting elements for which the stiffness cannot be determined by a rational engineering analysis as required by IBC Section 1604.4 is prohibited.
Installation on masonry walls or foundations or steel beams may be permitted, subject to the approval of the code official, provided calculations and construction details substantiating the connection to and adequacy of the supporting masonry or steel member supporting the Strong-Wall panel are prepared by a registered design professional. Where Strong-Wall panels are supported directly on steel beams, the additional top-of-panel drift contributed by beam deflection and the connection between panel and the beam, as applicable, must be added to the overall top-of-panel drift. Welding or modification of the hold-down is not permitted.
Strong-Wall panels may be stacked up to two stories provided the allowable values indicated in Tables 4, A5 and A6 of this report, as applicable, are not exceeded, and the anchorage force must include evaluation of cumulative overturning effect.
The foundation must be designed to resist all loads transferred, including overturning moment induced by the Strong-Wall panel. 4.1.2 Garage Portal Strong-Wall Panel Systems: Beams for garage portal systems must be designed for the load combinations specified in Section 1605.3 of the IBC. For all load combinations, gravity loads must be considered to induce only simple span moments in the beam. For load combinations that include lateral load, a concentrated end moment equal to the top of wall moment, noted in this section, must be placed at the end of the beam that is connected to the Strong-Wall panel according to the following: For 12-inch-wide (305 mm) panels with a height of 93¼ inches (2369 mm) or less, the moment induced into the header of the portal frame system must be taken as 20 percent of the total moment due to the in-plane lateral load; and for 18-inch-wide (457 mm) panels with a height of 93¼-inches (2369 mm) or less, the moment induced into the header of the portal frame system must be taken as 10 percent of the total moment due to the in-plane lateral load. Allowable values for panel models described above when using the portal straps described in Section 3.2.2.4 are provided in Table 3 of this report. For all other panel models, the total moment due to the in-plane lateral load is resisted at the base of the Strong-Wall panel and allowable values for standard application Strong-Wall panels shown in Table 2 of this report shall apply. The total moment due to the in-plane lateral load for the applicable panels is calculated as the design lateral shear times the panel height as defined in Table 1 of this report. 4.1.3 Braced Wall Panels: Each 12-inch-wide Strong-Wall panel, 9 feet (2740 mm) or less in height, and each 18- or 24-inch-wide Strong-Wall panel, 12 feet (3660 mm) or less in height, may replace each alternate braced wall panel or each 4 feet (1219 mm) of braced wall panel length specified in Section 2308.6 of the 2018 and 2015 IBC (Section 2308.9.3 of the 2012, 2009 and 2006 IBC, as applicable) and Section R602.10 of the IRC. The required length of bracing shall be based on wood structural panel sheathing (Method WSP in IBC and IRC).

4.1.4 Anchorage to Concrete: The anchorage-to- concrete details shown in Figure 6 of this report conform to Chapter 17 of ACI 318-14 under the 2018 and 2015 IBC (ACI 318-11 Appendix D under the 2012, 2009 and 2006 IBC) and may be used to anchor Strong-Wall panels provided the design anchor tension force does not exceed the allowable anchor tension due to overturning listed. Anchorage-to-concrete details shown in Figure 6 that are used for seismic resistance comply with the ductility requirements of ACI 318-14 Section 17.2.3.4.3 (ACI 318-11 Appendix D Section D.3.3.4.3). Tie or hairpin reinforcement in accordance with Figure 6 is not required for interior foundation applications (panel installed away from edge of concrete) or braced wall panel applications. Alternatively, subjected to approval of the code official, anchorage elements may be determined by a registered design professional and installed to resist tension and shear loads to accommodate the specific condition and critical load demand in accordance with Chapters 19 and 21 of the IBC, as applicable.
Strong-Wall panel anchorage solutions for grade beam applications conform to Sections 1901.3 and 1905 of the 2018 and 2015 IBC which refer to Chapter 17 of ACI 318-14 (Section 1909 of the 2012 IBC refers to ACI 318-11 Appendix D). Anchor reinforcement is required for grade beam applications. Anchor reinforcement described in Figure 6 detail 5-WSW1.1 provides a resistance that is equal to or greater than 1.2 times the nominal tensile strength of the steel anchor. Testing has shown that closed-tie anchor reinforcement is critical to maintain the integrity of the reinforced core where the anchor is located. In addition, plastic hinging must be prevented at anchor locations in seismic applications per ACI 318-14 Section 17.2.3.2 (ACI 318-11 Section D.3.3.2) to achieve expected anchor-to-concrete performance. Physical testing was used to validate anchor reinforcement configuration and placement, and has shown that in order to achieve expected performance, concrete member design strength should consider factored anchor demand for wind applications and amplified anchor demand for seismic applications. Figure 6 provides anchor reinforcement details and design moments to be applied at anchor locations. The amplified LRFD design seismic moments described in Figure 6 detail 5-WSW1.1 are based on the lowest of the following:
(1): 85 percent of the maximum lateral load resisted by the tested WSW panel when tested in accordance with AC130.
(2): WSW panel LRFD lateral strength multiplied by a 2.5 overstrength factor.
(3): Lateral shear based on the WSW panel overturning resistance at maximum anchor tension resistance. The WSW panel overturning resistance is based on using 1.2 times the anchor nominal tensile strength, and corresponding LRFD axial compression load, which is 1.2 times the allowable axial load listed in Table 2 of this report.
The design hold-down tension/uplift force due to overturning, T, for hold-down anchorage, assuming no resisting axial load, may be determined using the following formula:
𝑇 =𝑆ℎ𝑒𝑎𝑟 × 𝐻𝑒𝑖𝑔ℎ𝑡𝑀𝑜𝑚𝑒𝑛𝑡 𝐴𝑟𝑚
where:
• Shear = Applied design in-plane shear load for Standard and Portal Frame System Strong-Wall panel as applicable (lbs.).
• Height = Strong-Wall panel height per Table 1, A1 or A3, as applicable (in.).
• Moment Arm = 8 1/16 in., 13 15/16 in., and 19 15/16 in for 12-, 18-, and 24-inch-wide WSW respectively; 811∕16 in., 149∕16 in., and 195∕16 in. for 12-, 18-, and 24-inch-wide SWSBs, respectively.
The hold-down uplift force due to overturning for the 12-inch-wide Strong-Wall panels with heights less than or equal to 93.25 inches and 18-inch-wide Strong-Wall panels with heights less than or equal to 93.25 inches, when connected to a header/beam with portal straps in a garage portal frame system, may be taken as 80 percent and 90 percent, respectively, of the calculated hold-down uplift force due to overturning.
The hold-down uplift force due to overturning for stacked applications must take into account the effects of cumulative overturning. Base overturning moment, OM, as determined in accordance with Table 4 or A6 of this report, as applicable, may be substituted for shear x height in the preceding formula. 4.1.5 Anchorage to Masonry: Anchorage to masonry foundations or foundation walls for Strong-Wall panels described in this report must be designed and detailed by a registered design professional in accordance with Chapter 21 of the IBC and this report, and the design and details are subject to approval of the code official. 4.1.6 Anchorage to Steel Beams: Anchorage to steel beams for Strong-Wall panels described in this report must be designed and detailed by a registered design professional in accordance with Chapter 22 of the IBC and this report, and the design and details are subject to approval of the code official. Welding or modification of the hold-down is not permitted. 4.2 Installation: 4.2.1 General: The Strong-Wall panels must be installed within the wall envelope in accordance with the manufacturer’s installation instructions, the applicable code, and this report. Installation details shown in Figures 1 through 5 of this report represent typical surrounding framing conditions and connection requirements for standard, portal frame and multi-story Strong-Wall panel applications as referenced in this report. The WSW and SWSB may be field-trimmed to a minimum height of 74½ inches (1892 mm) per the manufacturer’s installation instructions. Field-drilling of the Strong-Wall panel is not permitted except as indicated in Figure 5.
Corrosion-resistant fasteners and connectors complying with Section 2304.10.5 of the 2018 and 2015 IBC (Section 2304.9.5 of the 2012, 2009 and 2006 IBC, as applicable) must be used when the Strong-Wall panel is in contact with fire-retardant or preservative-treated wood. The wood portion of the panel must not be in direct contact with concrete; the Strong-Wall panel is designed such that when installed on level and smooth concrete, there is a ⅛-inch (3 mm) gap between the wood at the bottom of the panel and the concrete. Anchor bolts and rods must be in accordance with Section 3.2.2.13 of this report and be placed using the form-mounted reusable template as described in Section 3.2.2.9 of this report.

4.2.2 Garage Portal Strong-Wall System: For portal frame applications, the header must be connected to the Strong-Wall panel using the connectors and/or fasteners described in Sections 3.2.2.1, 3.2.2.2, 3.2.2.3 and 3.2.2.5, as applicable.
The header must be connected to the Strong-Wall panel using four proprietary portal straps described in Section 3.2.2.4 (two on the front face and two on the back). In single portal frame installations, the header must be connected to the column with a connection capable of resisting a minimum allowable uplift of 1,000 pounds (4450 N). At the bottom of the column, a hold-down device capable of resisting a minimum allowable tension load of 1,000 pounds (4450 N) must be used to connect the column to the foundation. When using a 3⅛-inch-wide (79 mm) header in portal frame applications, a ⅜-inch-thick (9.5 mm) wood furring strip [2½ inches by 10 inches (64 mm by 254 mm), minimum] must be installed (on one side of the header) between the header and each steel strap. The furring strip must be connected to the header with 10-8d common nails. When using a 5⅛-, 5¼-, or 5½-inch-wide (130, 133, or 140 mm) beam, 13/4-inch-thick (44 mm) wood furring must be installed on the inside face of the Strong-Wall panel between the panel and both steel straps. The furring must be connected to the header with fasteners per Figure 3 of this report. 4.3 Special Inspection: 4.3.1 General: If special inspection is required, the inspector is responsible for verifying proper hold-down anchor type, size and placement, including embedment length, spacing, and edge distance.

1. Allowable ASD shear loads and anchor tension values are applicable to installations on concrete with specified compressive strengths as listed. No further increase for duration of load is allowed.
2. Allowable vertical load denotes the total maximum vertical load permitted on the panel acting in combination with the allowable shear loads. 3. Allowable shear, drift and anchor tension values may be interpolated for intermediate height or vertical loads. 4. For panels 74½"-78" tall, use the values for a 78" tall panel. 5. High strength anchor bolts are required unless a lower strength grade is justified by the registered design professional. Figure 6 of this report provides WSW-AB anchor bolt information
and anchorage solutions. 6. All panels taller than 18' require a 2x6 minimum full-height stud attached to each side. Attach using 10d common nails at 16" o.c. 7. See Table 5 of this report for allowable out-of-plane values; see Table 6 for allowable axial values. 8. Drifts at lower design shear may be linearly reduced. 9.

For SI: 1 inch = 25.4 mm, 1 lb. = 4.45 N.
1. Allowable ASD shear loads and anchor tension values are applicable to installations on concrete with specified compressive strengths as listed. No further increase for duration of load is allowed.
2. Allowable vertical load denotes the total maximum vertical load permitted on the panel acting in combination with the allowable shear loads. 3. Allowable shear, drift and anchor tension values may be interpolated for intermediate height or vertical loads. 4. For panels 74½"-78" tall, use the values for a 78" tall panel. 5. High strength anchor bolts are required unless a lower strength grade is justified by the registered design professional. Figure 6 of this report provides WSW-AB anchor bolt information
and anchorage solutions. 6. See Table 5 of this report for allowable out-of-plane values; see Table 6 for allowable axial values. 7. Allowable values shown apply to single-wall garage portal systems. For double-wall garage portal systems, allowable shear load may be taken as twice the table value. 8. Drifts at lower design shear may be linearly reduced. 9. Tabulated anchor tension values assume no resisting vertical load. Anchor tension loads at design shear values and including the effect of vertical load may be determined using the
following equation: T = [(k × V × H) / B] - P/2, where:
T = Anchor tension load (lb.); V = Design shear load (lb.); P = Applied vertical load (lb.); H = Panel height (in.) B = Moment arm (in.); 8.06" for WSW12, 13.94" for WSW18, 18.94" for WSW24 k = Portal factor; 0.80 for WSW12 panels 93¼" or less in height, 0.90 for WSW18 panels 93¼" or less in height, 1.00 for all other panels.
10. Allowable values shown in Table 2 of this report shall apply for WSW12 and WSW18 portal panels taller than 93¼", for WSW24 portal panels, and for all panels installed without the portal straps described in Section 3.2.2.4.

For SI: 1 inch = 25.4 mm, 1 lb. = 4.45 N.
1. Allowable ASD base moments and anchor tension values are applicable to installations on concrete with specified compressive strengths as listed. No further increase for duration of load is allowed.
2. Allowable vertical load denotes the total maximum vertical load permitted on the panel acting in combination with the allowable shear loads. 3. Allowable shear, drift, base moment and anchor tension values may be interpolated for intermediate height or vertical loads. 4. Two-Story Stacked panel combinations may consist of any height combination of equal width panels listed in these tables. 5. A multi-story kit (MSK) is required to attach the second-story panel to first-story panel. 6. High strength anchor bolts are required unless a lower strength grade is justified by the registered design professional. Figure 6 of this report provides WSW-AB anchor bolt information
and anchorage solutions. 7. The designer must verify that the cumulative overturning moment at the base of the first-story panel does not exceed the allowable base moment capacity. The overturning base
moment shall be determined using the following equation: MOT = (V1 × H1) + (V2 × H2), where:
MOT = Overturning base moment; V1 = Applied shear load to first-story panel; V2 = Applied shear load to second-story panel H1 = Height of first-story panel; H2 = Total assembly Height (H1 + Height of second-story panel + 5 in.)
8. Tabulated anchor tension values assume no resisting vertical load. Anchor tension loads at design shear values and including the effect of vertical load may be determined using the following equation:
T = MOT / B - P/2, where: T = Anchor tension load (lb.); P = Applied vertical load (lb.); MOT = Overturning moment, see Footnote 7 B = Moment arm (in.); 13.94" for WSW18, 18.94" for WSW24
9. First-story panel drift must comply with code drift limits; evaluate drift at the top of the first-story panel using the following equation: Δ = H1
2 / K × [(3 × V2 × H3) + (2 × Vbase × H1)], where: Δ = First-story panel drift; K = Stiffness of first-story panel per Table 4B; H1 = First-story panel height; H3 = Second-story panel height V2 = Applied shear load to second-story panel; Vbase = Sum of applied shear loads to first-story panel and second-story panel

For SI: 1 inch = 25.4 mm, 1 lb. = 4.45 N, 1 plf = 14.6 N/m. 1Loads shown are the maximum allowable load based on AC130 tests. For allowable loads with various support conditions, see Table A2. 2Hold-down uplift at allowable shear is based on a moment arm of 8.688 inches, 14.563 inches and 19.313 inches for 12-inch, 18-inch and 24-inch-wide panels respectively. In-plane shear must also be considered in hold-down anchor design. Values shown in the Table are at allowable stress design level resistance. No increase for duration of load is allowed. 3To calculate allowable shear loads and drifts for panels trimmed to heights between those listed, interpolate between nearest SWSB heights. Determine the hold-down uplift value in accordance with Section 4.1.4 of this report. 4All SWSB's taller than 18 feet require a 2x6 minimum full-length stud attached to the 3.5 inches edges of the panel. Attach studs to SWSB with 10d nails at 16" on-center spacing.

No increase for duration of load is allowed. 3To calculate allowable shear loads and drifts for panels trimmed to heights between those listed, straight line interpolate between nearest SWSB heights. 4To calculate allowable shear loads and drifts for panels with an axial load between those listed, straight line interpolation of values is allowed. 5Allowable Axial Loads and Allowable Shear Loads are assumed to act in combination with each other. 6All SWSB's taller than 18' require a 2x6 minimum full-length stud attached to the 3.5-inch edges of the panel. Attach studs to SWSB with 10d nails at 16 inch on-center spacing. 7Hold-down uplift at allowable shear is based on a moment arm of 8.688 inches, 14.563 inches and 19.313 inches for 12-inch, 18-inch and 24-inch SWSBs respectively. In-plane shear must also be considered in hold-down anchor design. 8Half of the applied axial load is assumed to be supported by each SWSB hold down device. 9See Section 4.1.1 for bearing plate details.

For SI: 1 inch = 25.4 mm, 1 lb. = 4.45 N, 1 plf = 14.6 N/m. 1Loads shown are the maximum allowable capacity based on AC130 tests. For allowable loads with various support conditions, see Table A4. 2Hold-down uplift at allowable shear is based on a moment arm of 8.688 inches, 14.563 inches and 19.313 inches for 12-inch, 18-inch and 24-inch panels respectively, reduced by a factor of 0.8 and 0.9 for 12-inch and 18-inch panels 93.25 inches or less in height, respectively. In-plane shear must also be considered in hold-down anchor design. Values shown in the Table are at allowable stress design level resistance. No increase for duration of load is allowed. 3Panels may be trimmed to a minimum height of 74½ inches. For panels trimmed to a height less than 78 inches, use allowable shear values shown for 78 inches height. To calculate allowable shear loads and drifts for panels trimmed to heights between those listed, interpolate between nearest SWSB heights or use the allowable load of the taller SWSB. Determine the hold-down uplift value in accordance with Section 4.1.4 of this report.

For SI: 1 inch = 25.4 mm, 1 lb. = 4.45 N, 1 plf = 14.6 N/m. 1Table values assume foundation and anchorage solutions shown in Figure 6. 2Hold-down uplift at allowable shear is based on a moment arm of 8.688 inches, 14.563 inches and 19.313 inches for 12-inch, 18-inch and 24-inch panels respectively. Calculated uplifts can be reduced by a factor of 0.8 and 0.9 for 12-inch and 18-inch panels 93.25", or less in height, respectively. In-plane shear must also be considered in hold-down anchor design. Values shown in the table are at allowable stress design level resistance. No increase for duration of load is allowed. 3Panels may be trimmed to a minimum height of 74½ inches. For panels trimmed to a height less than 78 inches, use allowable shear values shown for 78 inches height. To calculate allowable shear loads and drifts for panels trimmed to heights between those listed, interpolate between nearest SWSB heights or use the allowable load of the taller SWSB. Determine the hold-down uplift value in accordance with Section 4.1.4 of this report. 4To calculate allowable shear loads and drifts for a panel with an axial load between those listed, interpolation of values is allowed. Interpolate between nearest axial loads. 5Allowable Axial Loads and Allowable Shear Loads are assumed to act in combination with each other. 6Portal application must be connected directly to a concrete foundation or footing. 7Axial load can be a point load applied at any point on the top of the panel. 8See Section 4.1.1 for bearing plate details.

No increase for duration of load is allowed. 2To calculate allowable shear loads and drifts for panels trimmed to heights between those listed, interpolate between nearest SWSB heights. 3Allowable Axial Loads and Allowable Shear Loads are assumed to act in combination with each other. 4The 1st story SWSB must be the same width or wider than the 2nd story SWSB. 5Maximum Allowable Axial Load = 2nd story axial load (2,000) + 1st story axial load (4,000) = 6,000 lbs. 6Drift of the first story panel must comply with code drift limits. To calculate the drift at of the 1st story SWSB at allowable stress design levels, use ∆ = h1
2/K (3V2h3 + 2Vbaseh1), where: ∆ = drift of 1st story SWSB (inches) h1 = Height of 1st story SWSB (inches) h3 = Height of 2nd story SWSB (inches) V2 = Applied shear load on 2nd story SWSB (lbs) Vbase = Sum of the applied shear loads on 1st and 2nd story SWSBs (lbs) K (1st story brace) = from table above (lb-in2) See Figure 4 for illustrations.
7Half of the applied axial load is assumed to be supported by each SWSB hold down device. 8Total allowable shear at the top of the first floor panel. General Notes 1. Shear capacities shown are for individual panels only. To resist forces at both 1st and 2nd floors in a two-story application, check the shear at each story against the maximum capacity for
EACH panel. 2. Anchorage shall be per Figure 6, unless superseded by the design professional of record. 3. The Hold-down uplift force for stacked applications shall be taken as the base overturning moment, OM, divided by the moment arm in accordance with Section 4.1.4 of this report. 4.

For SI: 1 lbs. = 4.45 N, 1 ft.-lb. = 1.356 N-m. 1The maximum induced bending moment, shear and axial forces shown may be reduced linearly if the applied lateral shear load is less than the allowable in-plane shear load in Table A3 of this report. 2The maximum shear and axial load are constant along the length of the beam member. In a double portal system the moment reduces linearly from maximum value at the beam ends to zero at the beam mid-span. In a single portal system the moment reduces linearly from maximum value at the end with the SWSB to zero at the end with the column. 3The header member allowable stresses may be increased by 60% (CD = 1.6) in accordance with Table 2.3.2 of the National Design Specification® for Wood Construction (NDS) when designing the header member.
