Simpson Strong-Tie® Roof to Wall Connectors


Thank you for choosing Simpson Strong-Tie for your uplift connectors!

Steps to Choose an Uplift Connector:

  1. Determine roof uplift capacity required.
  2. Determine species of wood being connected.
  3. Enter table below and choose connector.
  4. Determine if lateral loads are required in addition to uplift loads. If so, lateral loads are listed here. See below for reducing capacity for loading in multiple directions.
  5. Install connectors using number and size of fasteners shown in this table.
  6. For more options for selection of connectors, see here.
  7. Install additional connectors to provide a continuous load path to the foundation. See here for more information on the continuous load path.

Table
  1. Allowable loads are based on a CD = 1.00. Increases are allowed for other durations per code to a maximum CD = 1.60.
  2. Method 1 - To be considered effective all Strong-Drive screws shall be installed within 12" of the applied concentrated load.
  3. Method 1 and Method 2 screws can be combined as required to transfer half of the applied load to the supporting truss.
  4. For uniform top chord loads, space Strong-Drive screws as required to transfer half of the applied load to the supporting truss.
  5. Web configurations other than those shown above may be used as allowed by the Truss Designer.
