In light of recent events in Seattle, the importance of seismic retrofitting specialists has come into focus for most residents. Seismic retrofitting is the process of strengthening a building or structure to withstand an earthquake better.
This is done by assessing the vulnerability of the building and making changes to the foundation, framing, and/or walls to make the structure more stable and less likely to collapse.
Seismic retrofitting is an important consideration for any business or homeowner in an earthquake-prone area. Though the upfront cost of retrofitting can be significant, it is nothing compared to rebuilding after a disaster.
In addition to the financial considerations, there is also a very real human cost to consider. A collapsed building can result in serious injuries or even loss of life. By retrofitting your building now, you can help protect your employees, customers, and family in the event of an earthquake.
How Seismic Retrofitting Is Done
There are several ways to retrofit a building, depending on the structure’s specific needs. The most common methods include the following:
Foundation bolting: This involves attaching the home’s frame to its foundation with large bolts or steel plates. This helps to prevent the frame from shifting during an earthquake and collapsing.
Bracing cripple walls: Cripple walls are short walls that run along the perimeter of a home between the foundation and the first-floor framing. These walls can be strengthened by adding plywood or sheathing along their length. This helps to prevent them from buckling during an earthquake.
Adding sway bracing: Sway bracing helps to stabilize a building by connecting the roof rafters to the wall studs. This provides additional support that helps keep the building from swaying during an earthquake.
Reinforcing attic and garage doors: Attic and garage doors are often overlooked when it comes to seismic retrofitting, but they can be one of the weakest points in a building’s structure.
By reinforcing these doors with additional bracing, you can help prevent them from flying open during an earthquake and causing damage to the rest of the building.
