Different Types of Hold-Downs

• Hold-downs to the foundation
  • Hold-downs that connect a shear wall to the foundation are
    • bolted, screwed or nailed to the end stud or added post.
  • Retrofit hold-downs anchor the wall to the footings using a threaded rod.
    • One end of the rod is adhesive set into a hole drilled in the foundation concrete.
    • Rod transfers the uplift force from the wall down into the foundation.

• Hold-downs connect walls through the floor
  • Hold-downs that connect two walls through a floor come in pairs; one above and one below.
  • Figure shows an example of hold-downs connecting the wall of a second story to a first story wall.
  • The hold-downs are bolted, screwed or nailed to their respective end stud or added post.
  • Uplift forces are then transferred from the wall above to the wall below through the threaded rod that is bolted to the hold-downs.
