Replaceable arc-shaped soft steel plate combined energy dissipation damper for beam-column joints

Abstract

The invention provides a replaceable arc-shaped soft steel plate combined energy dissipation damper for beam-column joints. The replaceable arc-shaped soft steel plate combined energy dissipation damper comprises an upper end plate and a lower end plate, wherein an inner arc energy dissipation mechanism and an outer arc energy dissipation mechanism are arranged between the upper end plate and thelower end plate; in the inner arc energy dissipation mechanism, an upper arc plate and a lower arc plate are fixedly connected through a plurality of groups of energy dissipation plates vertically penetrating through the upper arc plate and the lower arc plate, and the parts of each group of energy dissipation plates extending out of the outer side of the upper arc plate and the outer side of thelower arc plate are connected together through connecting pieces; and in the outer arc energy dissipation mechanism, a plurality of outer arc plates are fixed together in series by deformation bolts penetrating through arc grooves. According to the replaceable arc-shaped soft steel plate combined energy dissipation damper, the energy dissipation plates and the deformation bolts jointly bear the energy dissipation, and under the action of an earthquake, the energy dissipation plates and the deformation bolts are bent and deformed, so that the plastic deformation at the beam-column joint is reduced to ensure that a frame beam-column can still maintain good ductility after the earthquake, and the function of dissipating earthquake energy is achieved.

Description

technical field [0001] The invention belongs to the field of anti-seismic and shock-absorbing civil engineering, and relates to an energy-dissipating damper, in particular to a replaceable arc-shaped mild steel plate combined energy-dissipating damper for beam-column joints. Background technique [0002] Traditional buildings mainly rely on the deformation of the structure itself to absorb earthquake energy, and many major components are difficult to repair after damage. With the continuous advancement of anti-seismic theory, technology and methods and the development and application of more high-performance materials, people have higher and higher requirements for the anti-seismic performance of structures. After the earthquake, the loss of the whole society will be minimized. [0003] Among the several methods to realize the recoverable functional structure, the most operable is the replaceable structure. Replaceable structural components are set in the structure, and the...
