Abstract

The invention provides an energy dissipation and shock absorption mechanism. The energy dissipation and shock absorption mechanism comprises a metal damper, a supporting or rigid wall for arranging the damper, and a connecting device connected with a structure. Two external connecting mechanisms are arranged on the metal damper; one of the external connecting mechanisms is connected with other connecting structures on a building, and the other external connecting mechanisms is connected with the building through the supporting or rigid wall; and the connection is riveting, bolt pin connection, bolt connection or welding. The energy dissipation and shock absorption mechanism comprises the metal damper, so the compression performance of the metal is used for dissipating the energy; the hysteresis curve of the energy is saturated, namely, under the condition of very small deformation (such as small vibration), the energy dissipation and shock absorption mechanism can enter plastic energy dissipation from the full section; moreover, the required quantity of materials is low, so the energy dissipation and shock absorption mechanism is convenient to install and exchange; compared with the conventional stickness damper, the energy dissipation and shock absorption mechanism has the characteristics of long durability and maintenance freedom.
