A pure bending moment yield damper device

Abstract

The invention discloses a pure bending moment yield damper device, which includes a support frame connection port, an energy dissipation plate, a supporting plate, a guide groove, a shear key, a rolling support, and a lateral constraint masonry; the pure bending moment of the invention Yield damper device, uniform pressure distribution, pure bending moment generated by the energy dissipation plate at the extension part, high extension, effectively avoiding the axial force easily generated when the extension part is fixedly connected by welding, resulting in local plastic hinges and welds The ductility 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; the production cost is low, the operation and post-maintenance costs are low, the maintenance and replacement costs after severe earthquake disasters are 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 w...

Problems solved by technology

[0006] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is that in the prior art, during the use of the bending moment energy dissipator, the core components of the extended energy consumption are welded, etc., and the pressure distribution during use is prone to unevenness, and The extension part is easy to generate axial force, resulting in the reduction of the ductility of the local plastic hinge and welding; the defect of reducing the energy dissipation performance and poor energy dissipation effect
