Earthquake-proof Foam House
|
|
| Description |
The Federation of American Scientists (FAS), recently tested the stability of structures built with the combination of expanded polystyrene (foam), and cement board. This method of building maintains the rigidity needed, yet remains lightweight, so it can withstand earthquakes of magnitude 10. Remarkably, the structure doesn’t require any wood members to create a rigid frame. FAS is in the process of using this method to build an ‘elegant home’ .
When people die in earthquakes, they are often killed by their own houses collapsing on top of them. That could change if a new construction material similar to styrofoam is used instead of more traditional bricks and mortar.
In recent tests, a two-storey house built from panels of expanded polystyrene sandwiched between cement boards survived a simulated earthquake of magnitude 10, stronger than the world has ever experienced. The quakes that struck Turkey and Iran in 2003 both measured less than magnitude 7, but thousands died when large numbers of brick buildings collapsed.
The foam technology could help prevent such devastating loss of life. The material stands up to violent shaking because the foam is lightweight, while the cement coating makes it rigid - features that help a house to stand when others would fall.
Houses made from the composite panels are not only earthquake-proof, but also relatively cheap, simple to construct and energy-efficient.
