15 Wood Construction Connectors IMPORTANT INFORMATION GENERAL NOTES INSTRUCTIONS FOR THE DESIGNER a. The allowable load is limited to the lowest of deflection, lowest test ultimate/3 or calculation value. b. Allowable simultaneous loads in more than one direction on a single connector must be evaluated as follows: Design Uplift/Allowable Uplift Design Lateral Parallel to Plate/Allowable Lateral Parallel to Plate Design Lateral Perpendicular to Plate/Allowable Lateral Perpendicular to Plate 1.0. c. Loads are based on the 2001 National Design Specifications (NDS), unless otherwise specified. Other code agencies may use different allowable loads. d. Duration of load adjustments for fasteners into wood as specified by the code are as follows: FLOOR and DOWN (100) no increase for duration of load. SNOW (115) 115% of design load for 2 month duration of load. ROOF LOAD (125) 125% of design load for 7 day duration of load. EARTHQUAKE/WIND (133 and 160) 133% and 160% of design load for earthquake/wind loading. e. Unless otherwise noted, wood shear is not considered in the loads given; reduce allowable loads when wood shear is limiting. Glulam 145 psi, LVL 285 psi, LSL 285 psi, PSL 290 psi; E 1.3x10 6 psi. f. Simpson strongly recommends the following addition to construction drawings and specifications: Simpson Strong-Tie connectors are specifically required to meet the structural calculations of plan. Before substituting another brand, confirm load capacity based on reliable published testing data or calculations. The Designer/Engineer of Record should evaluate and give written approval for substitution prior to installation. g. Verify that the dimensions of the supporting member are sufficient to receive the specified fasteners, and develop the top flange bearing length. h. Some catalog illustrations show connections that could cause cross-grain tension or bending of the wood during loading if not sufficiently reinforced. In this case, mechanical reinforcement should be considered. i. For holdowns, anchor bolt nuts should be finger-tight plus to turn with a hand wrench, with consideration given to possible future wood shrinkage. Care should be taken to not over-torque the nut. Impact wrenches should not be used as they may preload the holdown. j. Simpson will provide, upon request, code testing data on all products that have been code tested. k. The allowable loads published in this catalog are for use when utilizing the traditional Allowable Stress Design methodology. A method for using Load and Resistance Factor Design (LRFD) for wood has been published in AF PA/ASCE 16. When designing with LRFD, reference lateral resistances must be used. Contact Simpson for reference lateral resistances of products listed in this catalog. For more information, refer to the American Forest and Paper Association Guideline to Pre-engineered Metal Connectors and ASCE 16. The Guideline contains a soft-conversion procedure that can be used to derive reference lateral resistances. l. Simpson recommends that hanger height be at least 60% of joist height for stability. m. The term Designer used throughout this catalog is intended to mean a licensed/certified building design professional, a licensed professional engineer, or a licensed architect. n. All connected members and related elements shall be designed by the Designer. o. All installations should be designed only in accordance with the allowable load values set forth in this catalog. Simpson Strong-Tie Co., Inc. warrants catalog products to be free from defects in material or manufacturing. Simpson Strong-Tie Co., Inc. products are further warranted for adequacy of design when used in accordance with design limits in this catalog, and properly specified and installed. This warranty does not apply to uses not in compliance with specific applications and installation procedures set forth in this catalog, or to non-catalog or modified products, or to deterioration due to environmental conditions. Simpson Strong-Tie connectors are designed to enable structures to resist the movement, stress, and loading that results from impact events such as earthquakes and high velocity winds. Other Simpson Strong-Tie products are designed to the load capacities and uses listed in this catalog. Properly-installed Simpson Strong-Tie products will perform in accordance with the specifications set forth in the applicable Simpson catalog. Additional performance limitations for specific products may be listed on the applicable catalog pages. Due to the particular characteristics of potential impact events, the specific design and location of the structure, the building materials used, the quality of construction, and the condition of the soils involved, damage may nonetheless result to a structure and its contents even if the loads resulting from the impact event do not exceed Simpson catalog specifications and Simpson Strong-Tie connectors are properly installed in accordance with applicable building codes. All warranty obligations of Simpson Strong-Tie Co., Inc. shall be limited, at the discretion of Simpson Strong-Tie Co., Inc., to repair or replacement of the defective part. These remedies shall constitute Simpson Strong-Tie Co., Inc.s sole obligation and sole remedy of purchaser under this warranty.
