Building structure energy absorption body refers to the building structure set up a suitable energy absorption body, energy absorption body can be composed of energy absorption body or diagonal brace, wall, beam or node and other supporting parts, metal buffer damper is a kind of energy absorption device with excellent energy consumption performance, simple structure, convenient production, low cost, easy to replace, with isolation bearing and isolation system. It can be used as an energy dissipation unit and a limiting device, or it can be used alone as an energy dissipation device in the real estate structure to provide additional damping and stiffness, which has a wide range of application prospects, so let's understand the characteristics of the metal buffer damper together!

After the metal enters the plastic state, it has good hysteresis characteristics and absorbs a lot of energy in the process of elastic-plastic hysteresis deformation, so it is used to manufacture metal buffer dampers of different types and structures. Scholars and engineers at home and abroad have taken the lead in developing a variety of types of metal energy dissipators. At present, the main applications are X-type, triangular and open-hole stiffness damping devices. Although the metal energy dissipator has good energy dissipation performance, the above shortcomings can be overcome due to the out-of-plane force form and the metal buffer damper in the form of in-plane force. However, the metal buffer damper with in-plane force may be bent out of the plane, resulting in a decrease in the energy dissipation capacity of the damper and unstable performance.
