Abstract
A seismic energy dissipation system for use with structures such as buildings, bridges and the like. The system includes a gravity frame, at least one reaction frame, and connection apparatus for connecting the gravity frame and the reaction frame. The connection apparatus includes springs for setting a period of response and energy dissipation units for dissipating energy within the structure, thus controlling the response of a structure with respect to internal forces, accelerations and deformations due to external excitations such as wind or earthquake.
