THGB/THGBH/THGW Truss Girder Hangers

THGB/THGBH/THGW

High-capacity, welded hangers for multi-ply girder trusses. The THGB series offers optional installation with Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws, and the bolted THGBH and THGW hangers offer higher design loads. For a lower-cost alternative that uses Strong-Drive SDS Heavy-Duty Connector screws instead of bolts and offers high load capacities, see the THGQ/THGQH series.

Material

  • 3 gauge

Finish

  • Simpson Strong-Tie® gray paint

Installation

  • Use all specified fasteners; see General Notes
  • All multiple members must be fastened together to act as a single unit
  • Maximum 11 7/8" bottom chord in the carrying member to allow for the minimum bolt end distance
  • Bolts must be installed symmetrically when using less than 8 bolts on the 8-bolt backplate
  • Girders must be adequately laterally braced to prevent excessive displacement due to secondary torsional stresses (Ref ANSI/TPI 1-2014 Section 7.5.3.5)

Options

  • See Hanger Options information.

Skewed Seat

  • THGB/THGBH/THGBV/THGBHV hangers can be skewed to a maximum of 45°.
  • The maximum allowable down load and uplift load for skew is 0.87 of the table load.

Dropped Bucket

  • THGBV/THGBHV backplates can be extended to allow for up to a 6" dropped bucket.
  • Allowable loads are 100% of the table loads.
  • Order as “X” version, specify the total backplate height, BK_PLT, equal to the hanger height (H) plus the dropped bucket amount (db). Ex: a THGBV3.62/9 with a 4" dropped bucket would have a total backplate height of 27 1/4".

Load Tables

  1. Uplift loads have been increased for wind or earthquake loading with no further increase allowed; reduce where other loads govern.
  2. A 3-ply carrying member is required for the THGW3-3 and THGW4-3; a 4-ply carrying member is required for the THGW3-4 and THGW4-4. For all other models, a minimum 2-ply carrying member is required.
  3. Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws require a minimum 2-ply (3") carrying member.
  4. Bolts and Simpson Strong-Tie Strong Drive screws are permitted to be installed through metal truss connector plates as approved by the Truss Designer, provided the requirements of ANSI/TPI 1-2014 Sections 7.5.3.4 and 8.9.2 are met.
  5. 10-10d nails for the carried member will achieve the maximum down loads. Uplift loads are 2570 lbs. for DF/SP and 2210 lbs. for SPF/HF. To achieve maximum uplift, install nails and bolts listed in the table.
  6. Loads for THGW models require that the supported member have minimum 2x6 end verticals to ensure end-grain bearing. Contact Simpson Strong-Tie for loads when horizontal members are bearing in the hanger seat.
  7. Wind (160) is a download rating.
  8. To achieve published loads, machine bolts (MB) into the girder truss shall be installed with the nut on the opposite side of the hanger with a standard cut washer (except THGW's). Standard cut washers are required for THGB and THGBH.
  9. NAILS: 10d = 0.148" dia. x 3" long. See other nail sizes and information.
