Scientists in Stanford university and others have developed earthquake resistant steel frames in which yielding of steel is used to dissipate the energy of the earth quake.

The steel frame structure contains replaceable cut steel plate ‘fuses’ which deform during the earthquake, and can be replaced easily afterwards.
