DSC Drag-Strut Connector

DSC

On This Page

The DSC drag-strut connector transfers the diaphragm shear forces from the girder truss or beam to the shearwalls. The DSC5 has been designed to optimize fastener location, resulting in a connector that outperforms the DSC4 with fewer fasteners. The DSC2 is a smaller, lighter version that installs with fewer screws.

Key Features

  • The DSC5 requires 40% fewer fasteners than our previous DSC4, and gets 12% higher loads
  • Left-hand and right-hand versions available
  • DSC connectors install with 1/4" x 3" Strong-Drive® SDS Heavy-Duty Connector screws (provided)

Material

  • DSC2 — 7 gauge; DSC5 — 3 gauge

Finish

  • DSC2 — galvanized; DSC5 — Simpson Strong-Tie gray paint

Installation

  • Use all specified fasteners; see General Notes
  • Strong-Drive SDS Heavy-Duty Connector screws are provided

Load Tables

DSC Drag Strut Connector Load Table
  1. Allowable loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
  2. Strong-Drive® SDS Heavy-Duty Connector screw minimum penetration is 2 3/4", minimum end distance is 2 1/2" for DSC2 and 3 3/4" for DSC5, and minimum edge distance is 5/8" for full load values.
  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).
