THGBV Truss Hanger for Girders, Bolted or Screwed

THGBV

On This Page

The THGBV is a bolted hanger designed for connecting multi-ply structural composite lumber (SCL) to girder trusses and attaches to a vertical web to support high loads. The THGBV has options for skewing or dropping the buckets to provide design flexibility for a variety of SCL-to-truss connections. This bolted hanger offers an installation option using Strong-Drive® SDS Heavy-Duty Connector screws.

Key Features

  • Can be skewed to a maximum of 45°. The maximum allowable download and uplift load for skew is 0.87 of the table load.
  • Backplates can be extended to allow for up to a 6" dropped bucket.
  • Available in 9″ and 11″ bucket heights to accommodate a range of SCL sizes.

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 fewer than the maximum number of bolts are used on the backplate
  • Girders must have adequate lateral bracing to prevent excessive displacement due to secondary torsional stresses (refer to ANSI/TPI 1-2014 Section 7.5.3.5)
  • Carrying member must be a minimum two-ply girder truss to allow for required minimum screw penetration

Options

Skewed Seat

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

Dropped Bucket

  • THGBV 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

THGB/THGBH/THGW/THGBV/THGBHV/THGWV Load Table
  1. Allowable loads are based on a SCL (LVL, PSL, or LSL) carried member with an allowable F'c ⊥ of 750 psi and equivalent Specific Gravity of 0.50 or higher.
  2. Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
  3. Strong-Drive® SDS Heavy-Duty Connector screws require a minimum two-ply (3") carrying member.
  4. Bolts and Strong-Drive® SDS Heavy-Duty Connector screws (not included) 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.
  5. Wind (160) is a download rating.
  6. 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. Standard cut-washers are required for THGBV.
  7. 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.
