Reinforce Building With Cross Bracing

Full-height, steel cross bracing can increase a building’s capacity to withstand seismic forces. Cross bracing can be exterior or interior and is secured to the building at floor level. 

Effectiveness:

  • Somewhat to very effective, depending on pre-disaster building condition and the extent of cross bracing.
  • Increase effectiveness by tying exterior walls to the floors.

Limitations:

  • Foundation must be able to support bracing. 
  • Multi-story cross bracing is less effective than cross bracing at each floor level.
