Abstract

The invention discloses a pure bending moment yield damper device. The pure bending moment yield damper device comprises supporting frame connectors, energy dissipation plates, supporting plates, guide grooves, shear keys, rolling supports and lateral constraint masonry. According to the pure bending moment yield damper device, the pressure distribution is uniform, the energy dissipation plates atthe extension part generate pure bending moment, the ductility is high, and it is effectively avoided that when the extension part is used in a welding fixed connection mode, axial force is likely tobe generated, local plastic hinges are caused, and the ductility of the welding position is reduced; the energy consumption performance of the device is improved, the energy absorption and shock absorption performance is high, and the energy consumption effect is good; and the manufacturing cost is low, the operation and later maintenance cost is low, the maintenance and replacement cost after serious earthquake disasters is low, and the applicability is good.

Description

technical field [0001] The invention relates to the technical field of mechanical construction, in particular to a pure bending moment yield damper device. Background technique [0002] In recent years, anti-lateral force systems have become more and more widely used. The lateral force is a horizontal force acting on the building structure for the entire building structure, such as wind force and earthquake force. The anti-lateral force system refers to the system that carries these horizontal forces. Structural damping control systems are widely used in lateral force resistance systems. The existing structural damping control systems mainly fall into three categories: active control systems, passive control systems, and hybrid control systems. The active control system uses multiple sensors, processing systems, and external energy to make the structure reasonably respond to ground excitation; the passive control system refers to the passive response of the system device...
