Title: Building system using shape memory alloy members

Abstract: A system and method is described by which the structural integrity of a building or other structure can be increased and made more resistant to earthquake damage. A structural member may be incorporated into a building structure. At least a portion of the structural member is made of a material that undergoes a shape or phase transformation in response to energy applied. This member can alter the natural frequency of the building structure from a first natural frequency to a second natural frequency when the material undergoes the transformation to make destructive resonance less likely to occur.
