Hurricane Ties for Plated Truss

This product's information may differ depending on the category of use. You are currently viewing details related to Hurricane Ties for Plated Truss. You can also view product information related to the category: Strong-Rod® URS Components

Simpson Strong-Tie® hurricane ties provide a positive connection between the truss/rafter and the wall of the structure to resist wind and seismic forces.

Material

  • See table

Finish

  • Galvanized. H7Z and H11Z — ZMAX® coating. Some models available in stainless steel or ZMAX. See Corrosion Information.

Installation

  • Use all specified fasteners; see General Notes.
  • H1 can be installed with flanges facing inward (reverse of "H1 Installation" drawing; see image gallery).
  • H2.5T, H3 and H6 ties are shipped in equal quantities of right and left versions (right versions shown).
  • Hurricane ties do not replace solid blocking.
  • When installing ties on plated trusses (on the side opposite the truss plate), do not fasten through the truss plate from behind. This can force the truss plate off of the truss and compromise truss performance.
  • H10A optional nailing to connect shear blocking: use 8d nails. Slots allow maximum field bending up to a pitch of 6:12; use H10A sloped loads for field-bent installation.

Considerations for Hurricane Tie Selection

  1. What is the uplift load?
  2. What is the parallel-to-plate load?
  3. What is the perpendicular-to-plate load?
  4. What is the species of wood used for the rafter and the top plates?
    (Select the load table based on the lowest-performing species of wood.)
  5. Will the hurricane tie be nailed into both top plates or the upper top plate only?
  6. What load or loads will the hurricane tie be taking?*
  7. Select hurricane tie based on performance, application, installed cost and ease of installation.

* When a connector is loaded simultaneously in more than one direction, the allowable load must be evaluated using option 1 or 2.

Option 1: Unity Equation

For all connectors use the following equation:

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.

The three terms in the unity equation are due to the possible directions that exist to generate force on a connector. The number of terms that must be considered for simultaneous loading is at the sole discretion of the Designer and is dependent on their method of calculating wind forces and the utilization of the connector within the structural system.

Option 2: 75% Rule

As an alternative, certain roof-to-wall connectors (embedded truss anchors, seismic and hurricane ties [on this page], and twist straps) can be evaluated using the following: The design load in each direction shall not exceed the published allowable load in that direction multiplied by 0.75.

Load Values with Carbon Steel Nails

    These products are available with additional corrosion protection. Additional products on this page may also be available with this option, check with Simpson Strong-Tie for details.

   These models are approved for installation with the Strong-Drive® SD Connector screw. See the load values below.

  1. Loads have been increased for wind or earthquake loading with no further increase allowed: reduce where other loads govern.
  2. Allowable loads are for one anchor. A minimum rafter thickness of 2 1/2" must be used when framing anchors are used on each side of the joist and on the same side of the plate (exeption: connectors installed such that nails on opposite side don't interfere).
  3. Allowable DF/SP uplift load for stud to bottom plate installation (see detail 15) is 390 lb. (H2.5A); 265 lb. (H2.5ASS); and 310 lb. (H8). For SPF/HF values multiply these values by 0.86.
  4. Allowable loads in the F1 direction are not intended to replace diaphragm boundry members or cross-grain bending of the truss or rafter members.
  5. When cross-grain bending or cross-grain tension cannot be avoided in the members, mechanical reinforcement to resist such forces may be considered.
  6. Hurricane Ties are shown on the outside of the wall for clarity and assume a minimum overhang of 3 1/2". Installation on the inside of the wall is acceptable (see General Instructions for the Installer notes s). For uplift continuous load path, connections in the same area (i.e. truss to plate connector and plate to stud connector) must be on the same side of the wall. See T-HTIEBEARING for more information.
  7. Southern Pine allowable uplift loads for H10A = 1,340 lb. and for the H14 = 1,465 lb.
  8. Refer to technical bulletin T-HTIEBEARING for allowable bearing enhancement loads.
  9. H10S can have the stud offset a maximum of 1" from rafter (center to center) for a reduced uplift of 890 lb. (DF/SP) and 765 lb. (SPF).
  10. H10S nails to plates are optional for uplift but required for lateral loads.
  11. Some load values for the stainless-steel connectors shown here are lower than those for the carbon-steel versions. Ongoing test programs have shown this to also be the case with other stainless-steel connectors in the product line that are installed with nails. See General Corrosion Risks for updated information.
  12. The allowable loads of stainless-steel connectors match carbon-steel connectors when installed with Simpson Strong-Tie stainless-steel, SCNR ring-shank nails. For more information, refer to engineering letter L-F-SSNAILS.
  13. Allowable DF/SP/SPF uplift load for the H2.5A fastened to a 2x4 truss bottom chord and double top plates using (5) 8d x 1 1/2" nails into the top plates and (3) 8d x 1 1/2" nails into the lowest three flange holes into the truss bottom chord is 260 lb. (160).
  14. Nails: 16d x 2 1/2" = 0.162" dia. x 2 1/2" long, 10d = 0.148" dia. x 3" long, 10d x 1 1/2" = 0.148" dia. x 1 1/2" long, 8d = 0.131" dia. x 2 1/2" long, 8d x 1 1/2" = 0.131" dia. x 1 1/2" long.
    See other nail sizes and information.
  15. Screws: Strong-Drive® SD #9 x 1 1/2" (model SD9112) = 0.131" dia. x 1 1/2" long (for the models marked with the orange flag only). Full table loads apply.
