ANY INC.
Simpson Strong-Tie Company Inc. structural connectors, anchors and other
products are designed and tested to provide specifi ed design loads. To obtain
optimal performance from Simpson Strong-Tie Company Inc. products and
achieve maximum allowable design load and design strength, the products
must be properly installed and used in accordance with the installation
instructions and design limits provided by Simpson Strong-Tie Company Inc.
To ensure proper installation and use, designers and installers must carefully
read the following General Notes, General Instructions for the Installer and
General Instructions for the Designer as well as consult the applicable catalog
pages for specifi c product installation instructions and notes. If you do not
understand the catalog, or if you have any questions, contact Simpson
Strong-Tie Company Inc. for further information. In addition to following all notes, warnings and instructions provided in the
catalog, installers, designers, engineers and consumers should consult the
Simpson Strong-Tie Company Inc. web site at
www.simpsonanchors.com to
obtain additional design and installation information.
Failure to follow fully all of the notes and instructions provided by Simpson
Strong-Tie Company Inc. may result in improper design or installation of
products. Improperly designed or installed products may not perform to the
specifi cations set forth in this catalog and may reduce a structure’s ability to
resist the movement, stress and loading that occurs from gravity loads as well
as impact events such as earthquakes and high velocity winds.
Simpson Strong-Tie Company Inc. does not guarantee the performance
or safety of products that are modifi ed, improperly installed, or not used in
accordance with the design and load limits set forth in this catalog.
These general notes are provided to ensure proper installation of
Simpson Strong-Tie Company Inc products and must be followed fully.
a) Simpson Strong-Tie Company Inc. reserves the
right to change specifi cations, designs, and models
without notice or liability for such changes.
b) Unless otherwise noted, dimensions are in
inches and loads are in pounds.
c) Do not overload, which will jeopardize the anchorage. Service loads shall
not exceed published allowable loads. Factored loads shall not exceed
design strengths calculated in accordance with published design data.
d) Some hardened fasteners may experience premature failure if exposed
to moisture. These fasteners are recommended to be used in dry
interior applications.
e) Do not weld products listed in this catalog. Some steel types
have poor weldability and a tendency to crack when welded.
WARNING
GENERAL NOTES
GENERAL INSTRUCTIONS FOR THE INSTALLER
These general instructions for the installer are provided to ensure the
proper selection and installation of Simpson Strong-Tie Company Inc.
products and must be followed carefully. These general instructions are in
addition to the specifi c design and installation instructions and notes provided
for each particular product, all of which should be consulted prior to and
during the installation of Simpson Strong-Tie Company Inc. products.
a) Do not modify Simpson Strong-Tie Company Inc. products. The
performance of modifi ed products may be substantially weakened.
Simpson Strong-Tie will not warrant or guarantee the performance of
such modifi ed products.
b) Do not alter installation procedures from those set forth in this catalog.
c) Drill holes for mechanical anchors with carbide-tipped drill bits meeting
the diameter requirements of ANSI B212.15 shown in the table below.
A properly-sized hole is critical to the performance of mechanical
anchors. Rotary-hammer drills with light, high-frequency impact are
recommended for drilling holes. When holes are to be drilled in archaic
or hollow base materials, the drill should be set to “rotation-only” mode.
d) For mechanical anchors that require a specifi c installation torque: Failure
to apply the recommended installation torque can result in excessive
displacement of the anchor under load or premature failure of the
anchor. These anchors will lose pre-tension after setting due to pre-load
relaxation. See Supplemental Topic M1 on page 14 for more information.
e) Do not disturb, bolt up, or apply load to adhesive anchors prior to the
full cure of the adhesive.
f) For powder-actuated fastening, refer to the Important Information
on page 183.
g) Use proper safety equipment.
