THGBV/THGBHV/THGWV SCL-to-Truss Girder Hangers

Product Details

An extension of the THGB/THGBH/THGW series, these high-capacity hangers are designed for attaching two-ply, three-ply or four-ply sized structural composite lumber (SCL) to a girder truss. The THGBV offers optional installation with Strong-Drive^® SDS Heavy-Duty Connector screws, while the bolted THGBHV and THGWV offer higher load capacities. Two bucket heights are available for each width to accommodate a range of SCL sizes. Options for skewing or dropping the buckets for conditions where the SCL joist is lower than the girder bottom chord provide additional design flexibility for a variety of SCL-to-truss connections.

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).
Shall be attached to a two-ply girder truss to allow for required minimum screw penetration. Strong-Drive SDS Heavy-Duty Connector screws require a minimum two-ply (3") carrying member.

Options

Skewed Seat

THGBV/THGBHV 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/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 (d_b). 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

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.
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 THGWV5.50 /9 and THGWV5.50 /11; a four-ply carrying member is required for the THGWV7.25 /9 and THGWV7.25 /11.
Strong-Drive® SDS Heavy-Duty Connector screws require a minimum two-ply (3") carrying member.
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.
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 THGWVs). Standard-cut washers are required for THGBV and THGBHV.
Fasteners: Nail dimensions in the table are listed diameter by length. SDS screws are Simpson Strong-Tie® Strong-Drive SDS Heavy-Duty Connector screws. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
