Description
These high-capacity, welded hangers are designed for attaching multi-ply girder trusses. The THGB series offers optional installation with Strong-Drive® SDS Heavy-Duty Connector screws, and the bolted THGBH and THGW hangers offer higher design loads. See the THGQ/THGQH series for a lower-cost alternative that uses Strong-Drive SDS Heavy-Duty Connector screws instead of bolts and offers high-load capacities.
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 fewer than eight bolts on the eight-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
Skewed Seat
- THGB/THGBH 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
- THGB/THGBH 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
- Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
- A three-ply carrying member is required for the THGW3-3 and THGW4-3; a four-ply carrying member is required for the THGW3-4 and THGW4-4. For all other models, a minimum two-ply carrying member is required.
- Strong-Drive® SDS Heavy-Duty Connector screws require a minimum two-ply (3") carrying member.
- Bolts and Strong Drive® screws may 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.
- (10) 0.148" x 3" nails for the carried member will achieve the maximum downloads. Uplift loads are 2,570 lb. for DF/SP and 2,210 lb. for SPF/HF. To achieve maximum uplift, install nails and bolts listed in the table.
- 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.
- Wind (160) is a download rating.
- To achieve published loads, install bolts into the girder truss with the nut on the opposite side of the hanger with a standard-cut washer (except THGWs). Standard-cut washers are required for THGB and THGBH.
- Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
