Install Tension Ties Between Elements

During an earthquake, many unreinforced masonry and wood buildings suffer damage or even collapse due to inadequate connections between the walls and the roof/floor systems. Tying the walls to the roof and floor systems using tension ties can strengthen these buildings. Tension ties limit wall deflections by tying them to the floor system, thereby reducing the likelihood of damage or building failure. 

Effectiveness:

  • Very effective.
  • Consider adding shear anchors to the walls to increase effectiveness.
