Abstract
A motion-magnifying seismic shock-absorbing construction for placement in the frame of an extremely stiff building structure wherein there is a relatively small horizontal movement between the floors of the building in response to a seismic event including a first link connected to the structure and having a shock-absorbing member therein, a plurality of additional links connected between the structure and the first link to transmit to the first link and to the shock-absorbing member therein the relatively small horizontal movement between the floors of the structure due to the seismic event, and the plurality of links including a motion-magnifying linkage for magnifying the aforementioned relatively small relative movement so that a magnified movement is applied to the shock-absorbing member. A building structure containing a plurality of the above motion-magnifying shock-absorbing constructions.
