Example Embodiment

[0037] The present invention will be further described in detail below with reference to the accompanying drawings, which is an explanation rather than a limitation of the present invention.

[0038] Such as figure 1 As shown, a damper for strengthening beam and column nodes includes an elastic device and two energy dissipation devices for consuming seismic energy of the beam and column. The energy dissipation device consumes the seismic force at the beam and column nodes through stagnant deformation. The two ends of the device are hinged to each other, the elastic device is installed between the two energy consuming devices, and the two energy consuming devices can compress or stretch the elastic device.

[0039] The damper is installed at the node of the beam and column. The two energy dissipating devices undergo plastic deformation under the seismic force transmitted by the beam and column, and undergo repeated relative or opposite movement under the action of stagnation deformat...

Abstract

The invention discloses a damper for reinforcing nodes of beams and columns. The damper comprises an elastic device and two energy consumption devices, the energy consumption devices dissipates earthquake force of the nodes of the beams and the columns through hysteresis deformation, two ends of the energy consumption devices are hinged to each other, and the elastic device is mounted between theenergy consumption devices and can be compressed or elongated when hysteresis deformation of the energy consumption devices occurs. The damper adopts two energy consumption devices made of soft steeland deforms plastically under the effect of the earthquake force, the soft steel has good hysteresis characteristics after entering a plastic state and absorbs a large amount of energy during elastoplastic hysteresis deformation, therefore, most of the earthquake power applied to the beams and the columns can be dissipated, and the stability of nodes of the beams and the columns is improved; meanwhile, the energy consumption devices are made of the soft steel and accordingly are easier to machine, and the damper is stable in hysteresis, easy to replace and low in construction and maintenance cost.

Description

technical field [0001] The invention relates to the technical field of building structures and damper equipment, in particular to a damper for reinforcing beam-column joints. Background technique [0002] With the rapid development of national infrastructure construction, the requirements for building anti-seismic are getting higher and higher. Therefore, in order to increase the stability of beam and column joints, dampers are generally installed at the joints to consume the seismic capacity of beams and columns and to improve beam and column joints. the stability of the place. [0003] However, the existing dampers for strengthening beam and column joints have certain defects in the consumption of seismic energy, such as: the existing dampers have complex structures and do not use the replacement of damping components; and the energy dissipation mechanism is single, resulting in , the effect of consuming seismic energy is not significant; especially in strong earthquakes,...
