URS Run Starts

Typically, rod runs will terminate at the foundation, using the dead load of the concrete to ultimately resist the uplift demands. The building code does, however, allow the designer or Engineer of Record to use a percentage of the dead load expected to exist during a wind event (with the percentage based on load combinations for either Strength or Allowable Stress Design). Consequently, if the uplift loads are low enough and dead loads are high enough, it is possible to terminate the rod runs underneath upper wood floors.
