THGQ/THGQH/HTHGQ Girder Hangers for SCL or Truss Girders Attached to Truss

Allowable Loads for Multi-Ply Truss Girder

1. Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
2. Connector must be installed centered on girder vertical webs.
3. Strong-Drive® SDS Heavy-Duty Connector screws may be installed through metal truss 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 (predrilling required through the plate using a 5/32" bit maximum).
4. Strong-Drive® SDS Heavy-Duty Connector screws that penetrate all plies of the supporting girder (screws must penetrate a minimum of 1" into the last truss ply) may also be used to transfer the load through all the plies of the supporting girder. When SDS Heavy-Duty Connector screws do not penetrate all plies of the supporting girder truss, supplemental SDS screws at the hanger locations may be required to transfer the load to the truss plies not penetrated by the face fasteners, as determined by the Designer.
5. The supporting girder truss must have adequate thickness to accommodate the screw length, so that the screw does not protrude out the back of the girder. 3"- or 4 1/2"-long Strong-Drive® SDS Heavy-Duty Connector screws may be substituted for longer SDS screws with no load reduction.
6. For installations to LSL, use 1/4" x 3" Strong-Drive® SDS Heavy-Duty Connector screws and use the DF/SP table loads.
7. Wind (160) is a download rating.

Allowable Loads for Heavy Multi-Ply Truss Girder

1. Tabulated allowable loads must be selected based on duration of load as permitted by the applicable building code.
2. Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
3. Wind (160) is a download rating.
4. Connector must be installed centered on a minimum 2x10 vertical web.
5. A minimum three-ply carrying member is required for the tabulated loads.
6. Carrying truss plies must be adequately fastened together as determined by the Designer.
7. Truss chord cross-grain tension may limit allowable loads in accordance with ANSI/TPI 1-2014. Simpson Strong-Tie® Connector Selector® software includes the evaluation of cross-grain tension in its hanger allowable loads. For additional information, contact Simpson Strong-Tie.
8. Strong-Drive® SDS Heavy-Duty Connector screws may be installed through metal truss 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 (predrilling required through the plate using a 5/32" bit maximum).

Allowable Loads for Structural Composite Lumber (SCL)

See THGQ footnotes above

1. For Hem-Fir or Spruce-Pine-Fir members, multiply tabulated allowable loads for the skewed THGQH by 0.86. Connector must be installed centered on girder vertical webs
