Steel frames do it again! This time it is the tenacity and flexibility of steel frames that have made them a strong guard against seismic activities. Researchers at Stanford and Illinois University unitedly actualized an earthquake-proof structural system for buildings that can withstand an earthquake of 7 magnitude.
The system is engineered to hold a multistory building together during a destructive earthquake. This new structural system has been invented to make buildings more damage-resistant and easy to repair. How, you ask? Steel frames incorporated into the building system;around the core and on exteriors embrace all the impact that is generated during a quake, allowing an earthquake-hit building to avoid damage or acute destruction.
Steel Frames in Earthquake-proof building effectively combat damage
The system has been tested in Japan and has proved out to be a successful venture. The testing was brought about on a massive shake table, wherein the system survived counterfeit earthquakes of magnitude 7 and slightly beyond.
Not only will a building be able to hold itself together but also return to its upright position post the earthquake. However, the damage would be just confined to some easily replaceable parts and residents would be able to reoccupy the building quickly.
There are steel tendons installed to the center of steel frames which run down from top to bottom. This results in rebounding of the structure to its normal position and gaining proper alignment after the shaking stops. At the bottom of the frame, there are steel fuses as well which further help them withstanding extreme damage.
