Abstract

The invention discloses a wind-resistant and anti-seismic device for a coupling beam. The wind-resistant and anti-seismic device comprises a viscoelastic damper and an O-shaped metal damper which are arranged in series; the viscoelastic damper comprises a first connecting piece, side steel plates, viscoelastic material layers, a middle plate and a second connecting piece; a T-shaped connecting piece is adopted as the first connecting piece, the two sides of the middle protruding portion of the first connecting piece are each provided with one side steel plate, a T-shaped connecting piece is adopted as the second connecting piece, the middle plate is arranged on the middle protruding portion of the second connecting piece, the middle plate is inserted into a gap formed between the two side steel plates, and the spaces formed between the middle plate and the two side steel plates are each provided with one viscoelastic material layer; the side, different from the middle protruding portion, of the second connecting piece is provided with the O-shaped metal damper; the side, different from the middle protruding portion, of the first connecting piece is used for being connected with an embedded part arranged in a wall body, and the O-shaped metal damper is used for being connected with an embedded part arranged in a wall body on the other side. The wind-resistant and anti-seismic device for the coupling beam is simple in structure, easy to machine, good in energy consumption property, convenient to construct and beneficial for seismic rehabilitation and replacement.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a coupling beam wind and earthquake resistance device. Background technique [0002] Mild steel metal dampers are displacement-related dampers, which are popular because they are economical, practical, take up little space, are easy to manufacture and process, and can absorb a large amount of energy during moderate and large earthquakes. The energy dissipation principle of the mild steel metal damper is to reduce the dynamic response of the structure through the good hysteresis performance of the metal material after entering the elastic-plastic range. It can be reciprocated and deformed hundreds of times without breaking under the plastic strain which is dozens of times higher than the yield strain, so as to achieve the purpose of energy dissipation and shock absorption. However, under the action of small earthquakes or wind vibrations, metal materials are in the elas...

Problems solved by technology

However, the performance of viscoelastic dampers varies greatly with ambient temperature and load frequency, and viscoelastic materials are mostly thin layers, with limited shear deformation capacity, and are not suitable for large deformation seismic structures.

[0004] Today, structural design is increasingly emphasizing comfort, and at the same time it must meet the requirements of energy dissipation and shock absorption under large earthquakes and large displacements. It is difficult for a damper to meet the above two design requirements at the same time.
