Earthquake Brace & Bolting
Surrounding the crawl space under the first floor, many houses have a short wood framed wall (“cripple wall”) that needs to be strengthened to help prevent the house from sliding or toppling off of its foundation during an earthquake. Strengthening involves adding anchor bolts and plywood bracing in the crawl space.
Bolt: add anchor bolts and sill plates in the crawl space to improve the connection between the wood framing of the house and its concrete foundation to help keep the house from sliding.
Brace: strengthen the cripple walls in the crawl space with plywood will help keep the house from toppling off of the foundation during an earthquake. Strengthening cripple walls enables them to function as shear members, significantly protecting the house from collapsing.
Strap and Brace the Water Heater: properly strap and brace the water heater to reduce the likelihood of water and fire damage, and to protect the water supply.
