panels.
Project Name / Project No. / Date 06 12 19 - 2 Shear Wall Panels
3.2 INSTALLATION
A. All specified fasteners must be installed according to the manufacturer's instructions.
B. Install all specified fasteners before loading the prefabricated wood shear panel.
C. For all framing members other than the prefabricated wood shear panel, wood shrinkage shall
be taken into account.
D. Do not overload by exceeding the manufacturer's catalog allowable load values.
E. Use proper safety equipment.
F. Drilling, sawing, sanding or machining wood products generates wood dust, a substance
known to the state of California to cause cancer. For more information on Prop 65, visit
www.oehha.ca.gov.
G. Choose the correct template from the manufacturer, required for proper bolt placement.
H. The prefabricated wood shear panels shall be installed directly on concrete foundations,
masonry foundations or walls, or steel beams per the manufacturer's instructions. There may
be a reduction in allowable load if a prefabricated wood shear panel is installed on a masonry
foundation or a steel beam.
I. Concrete installation: The Prefabricated wood shear panel must be installed directly on a
concrete foundation over two anchor bolts per the manufacturer's instructions. The panel
holdowns must be secured to the anchor bolts with high strength nuts.
J. Masonry or steel installation: Installation of the prefabricated wood shear panels on masonry
walls or foundations or steel beams may be permitted, subject to the approval of the code
official based on calculations and details prepared by the registered design professional.
K. Field trimming or drilling must be performed in accordance with the manufacturer's allowable
guidelines.
L. The top of the prefabricated wood shear panel may be field cut up to a 45-degree slope to
accommodate rake wall applications per the manufacturer's instructions.
M. Prefabricated wood shear panels may also be used in 2x6 wall framing. Install with wall flush
to one face of the framing and add furring to the opposite side.
N. Prefabricated wood shear panels may be installed with solid or multi -ply headers per the
manufacturer's instructions.
O. The top of the prefabricated wood shear panel must be attached to wood top plates or a beam
with shear transfer plates (WSW -TOW), per the manufacturer's instructions.
P. The maximum shim thickness between the top of the prefabricated wood shear panel and the
top plates or header is 7/8".
Q. Garage Portal System: Installation of the prefabricated wood shear panels with the portal
frame connection kit (WSW-PK) shall be per the manufacturer's instructions. The kit is included
with all panels 100" or less in height and must be ordered separately for panels over 100-
inches tall. The WSW -PS straps shall be attached to the prefabricated wood shear panel and
to the wood header with 10d x 2'/z" (0.148" x 2'/2") minimum nails. The header must span
continuously across the length of the panel. Single -wall portal header support shall be installed
per the manufacturer's instructions.
R. Balloon Framing Installation: Install panels per the manufacturer's instructions. For panels over
18 ft. tall, a minimum of one nominal 2-by-6, spruce -pine -fir stud grade or better stud must be
installed on each side of the panel using 10d common (0.148" x 3") nails at 16" on center.
Alternate full height members may be required by the registered design professional. The
attachment to the full height studs and at the top and bottom of the balloon -framed panels
must be per the manufacturer's or registered design professional's instructions.
S. Two-story stacked installation: Installation of the stacked prefabricated wood shear panels
shall be per the manufacturer's instructions. The second -story panel height must include the
wall height plus the total depth of the floor system; verify panel height per manufacturer's
instructions. The second -story panel shall be the same width as the first story panel. The multi-
story connection kit (WSW-MSK), which contains an LSL bearing block and holdowns with pre -
attached bolts must be installed. The LSL bearing block shall be inserted between the double
top plate and second story panel. The MSK holdowns shall be attached to the first story panel
with 10d x 2'/2" minimum nails and to the second story panel with the washers and nuts
supplied with the upper panel.
Project Name / Project No. / Date 06 12 19 - 3 Shear Wall Panels
T. Anchor bolt nuts should be finger -tight plus % turn with a wrench. Do not use an impact wrench
to tighten nuts on the anchor bolts.
U. Nail tools with hole -locating mechanisms may be used to attach approved connectors to the
prefabricated wood shear panel as required by the manufacturer.
3.3 FIELD QUALITY CONTROL
A. Determine that the proper part is being used in the correct application and has been fabricated
by the approved manufacturer by observation of the stamp into the metal part and/or the
adhesive label on the product denoting part and manufacturer name.
B. Before substituting another brand, confirm load capacity based on published testing data and
calculations per Section 2.4. The engineer/designer of record shall evaluate and give written
approval for substitution prior to installation.
