H/TSP Seismic and Hurricane Ties


Installation

View step-by-step installation instructions

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

Material: See tables.

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

Installation:

SD9 & SD10 Compatible

Some products may be installed with the Strong-Drive® SD Structural Connector screw -

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 as shown here. 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 possible directions that exist to generate force on a hurricane tie. The actual number of terms used in the equation for each condition is dependant on designer’s method of calculating wind forces and the utilization of the tie in the structural system.

As an alternate, 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.

Both connectors shall be same model.
Install diagonally across from each other for minimum 2x truss. Products can be on the same side of the wall provided they are configured as shown. Nailing into both sides of a single ply 2x truss may cause the wood to split.

Additional Corrosion Protection

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 Structural-Connector screw.
See the load values below.
Table
  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 installed on each side of the joist and on the same side of the plate (exception: connectors installed such that nails on opposite sides don’t interfere).
  3. Allowable DF/SP uplift load for stud to bottom plate installation (see detail 15) is 400 lbs. (H2.5); 390 lbs. (H2.5A); 360 lbs. (H4) and 310 lbs. (H8). For SPF/HF values multiply these values by 0.86.
  4. Allowable loads in the F1 direction are not intended to replace diaphragm boundary members or prevent 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 installed 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 u). For uplift Continuous Load Path, connections in the same area (i.e. truss to plate connector and plate to stud connector) must be on same side of the wall.
  7. Southern Pine allowable uplift loads for H10A = 1340 lbs. and for H14 = 1465 lbs.
  8. Refer to technical bulletin T-HTIEBEARING for selected hurricane ties 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 lbs. (DF/SP), and 765 lbs. (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. Visit www.strongtie.com/corrosion for updated information.
  12. NAILS: 16dx2 1/2 = 0.162" dia. x 2 1/2" long, 10d = 0.148" dia. x 3" long, 10dx1 1/2 = 0.148" dia. x 1 1/2" long, 8d = 0.131" dia. x 2 1/2" long, 8dx1 1/2 = 0.131" dia. x 1 1/2" long. See other nail sizes and information.
  13. SCREWS: Strong-Drive® SD #9x1 1/2" (model SD9112) = 0.131" dia. x 1 1/2" long (for the models marked with the orange flag only). See load values below.
Table
  1. Loads have been increased for wind or earthquake loading with no further increase allowed; reduce where other loads govern.
  2. When cross-grain bending or cross-grain tension cannot be avoided, mechanical reinforcement to resist such forces should be considered.
  3. HS24 DF/SP allowable loads without slant nailing are 605 lbs. (uplift), 590 lbs. (F1), 640 lbs (F2). For SPF/HF loads multiply these values by 0.86.
  4. For H16-2S, S = short.
  5. Allowable loads in the F1 direction are not intended to replace diaphragm boundary members or prevent cross grain bending of the truss or rafter members. Additional shear transfer elements shall be considered where there may be effects of cross grain bending or tension.
  6. NAILS: 10dx1 1/2 = 0.148" dia. x 1 1/2" long, 8d = 0.131" dia. x 2 1/2" long, 8dx1 1/2 = 0.131" dia. x 1 1/2" long.
