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

Allowable Loads for Multi-Ply Truss Girder

1. Allowable uplift loads have been increased for wind or earthquake loading with no further increase allowed; reduce where other loads govern.
2. Connector must be installed centered on girder vertical webs.
3. Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws are permitted to be installed through metal truss plates as approved by the Truss Designer, provided the requirements of ANSI/TPI 1-2014 Section 7.5.3.4 and 8.9.2 are met (pre-drilling required through the plate using a maximum of 5/32" bit).
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 Strong-Drive SDS Heavy-Duty Connector screws do not penetrate all plies of the supporting girder truss, supplemental Strong-Drive SDS Heavy-Duty Connector 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 the longer Strong-Drive SDS Heavy-Duty Connector screws with no load reduction.
6. For installations to LSL, use 1/4"x3" Strong-Drive SDS Heavy-Duty Connector screw 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. The uplift loads have been increased for wind or earthquake loading with no further increase allowed. Reduce when other load durations govern.
3. Wind (160) is a download rating.
4. Connector must be installed centered on minimum 2x10 vertical web.
5. A minimum 3-ply carrying member is required for the tabulated loads.
6. Carrying truss plies must be adequately fastened together as determined by Designer.
7. Truss chord cross-grain tension may limit allowable loads as determined by the Designer in accordance with ANSI/TPI 1-2014.
8. Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws are permitted to be installed through metal truss plates as approved by the Truss Designer, provided the requirements of ANSI/TPI 1-2014 Section 7.5.3.4 and 8.9.2 are met (pre-drilling required through the plate using a maximum of 5/32" bit).
