The THGBH is a high-capacity bolted hanger designed for installing multi-ply girder trusses. This welded hanger attaches to a vertical web and is designed with a backplate to support higher loads. The bolted THGBH offers high design load capacities and easy installation.
Can be skewed a maximum of 45°. The maximum allowable down load and uplift load for skew is 0.87 of the table load.
Simpson Strong-Tie gray paint. HDG available; see Corrosion Information.
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 18.104.22.168)
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.
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 22.214.171.124 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.
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. Standard cut-washers are required for THGBH.
