3. Reinforce or Strap Chimneys.
4. Reinforce Masonry Walls.
5. Reinforce the soft-story above the garage.

What is seismic retrofit work?

Seismic retrofitting is the process of strengthening a home so that it is more resilient to damage in earthquakes. This process often involves strengthening weak connections such as those found at or near the foundation or roof.

What makes a house earthquake proof?

To withstand collapse, buildings need to redistribute the forces that travel through them during a seismic event. Shear walls, cross braces, diaphragms, and moment-resisting frames are central to reinforcing a building. Made of panels, these walls help a building keep its shape during movement.

Why seismic retrofitting is important?

Getting seismic retrofitting done for your home makes it resistant to seismic activity caused by earthquakes. This technique is used to prevent displacement from the concrete foundation of the home structure. It improves the stability and safety levels of the structure.

Why is it necessary to retrofit buildings after an earthquake?

The goal of the mandatory retrofit programs, under the ordinance, is to reduce these structural deficiencies and improve the performance of these buildings during earthquakes. Without proper strengthening, these vulnerable buildings may be subjected to structural failure during and/or after an earthquake

Are there mandatory retrofit programs in Los Angeles?

The City of Los Angeles recently passed Ordinance 183893, which requires the retrofit of pre-1978 wood-frame soft-story buildings and non-ductile concrete buildings.
