Problems solved by technology

The existing anti-buckling braces generally do not yield under the action of small earthquakes, and only enter the plastic state under moderate and large earthquakes, which consumes seismic energy. Therefore, its energy dissipation capacity has not been fully utiliz

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.

Description

technical field [0001] The invention relates to the field of engineering structures, in particular to an energy dissipation and shock absorbing mechanism. Background technique [0002] The energy dissipation and shock absorption of building structures refers to the installation of appropriate energy dissipation components in the building structure. The energy dissipation components can be composed of energy dissipation and shock absorption devices and supporting components such as braces, walls, beams or nodes. The metal damper is an energy-dissipating shock-absorbing device with superior energy-dissipating performance, simple structure, convenient manufacture, low cost and easy replacement. It can be used as an energy-dissipating unit or a limiting device in conjunction with a seismic-isolation support or a seismic-isolation system, and it can also be used alone in a building structure as an energy-dissipating device to provide additional damping and stiffness. It has broa...
