Description

An axial tension-compression metal yield energy dissipation damper

technical field

The utility model belongs to the technical field of shock absorption in civil and structural engineering, and relates to a damper, in particular to an axial pull-compression metal yield energy-consuming damper.

Background technique

At present, in the field of building structure design, in order to make the building structure have a strong ability to resist external force damage such as earthquakes or wind loads, it is often necessary to add energy-dissipating components to the frame structure, and there are many types of energy-dissipating components that have been developed. The main types are displacement-type metal yield energy dissipation dampers and friction dampers, velocity-type viscous dampers, and velocity-displacement hybrid viscoelastic dampers. Among the above-mentioned dampers, metal yield energy dissipation dampers are widely used because of their stable performance, low price, and high reliability.

Nowadays, most of the metal dampers used are shear-loaded dampers. The upper and lower end steel plates are connected to the bottom of the frame beam and the top of the lower herringbone support through anchor bolts or welding. A shear type metal bending energy dissipation damper, comprising an upper connection plate and a lower connection plate fixed on a building structure, and a core metal energy dissipation element, the metal energy dissipation element is at least one piece of metal capable of energy dissipation through bending The two ends of the metal plate are fixedly connected to the upper connecting plate and the lower connecting plate respectively, and are perpendicular to the upper connecting plate and the lower connecting plate; the thickness direction of the metal plate is consistent with the direction in which the building structure bears the shear force. The technical solution published in this patent uses metal materials with good plastic deformation ability such as steel to achieve energy dissipation, but the vertical displacement caused by the sideways movement between the frame structure and the vertical deformation of the damper is generally different. It is easy to cause local damage to the main structure. At the same time, the seismic waves generated during the earthquake are all three-directional, and the seismic action perpendicular to the plane of the damper arrangement will also impose a certain out-of-plane load on the damper, thereby causing out-of-plane buckling of the damper. or destabilizing damage.

In order to overcome the deficiency of the connection mode of the metal damper and reduce the possible damage to the main structural components during the earthquake, it is of great engineering application value to develop a tension-compression metal yield energy-dissipating damper.

At this time, the damper only Under axial tension and compression loads, in order to prevent instability, the thickness of the center plate of the damper should be greater than 30mm. According to the current seismic design code, the net distance between the two center plates is generally 120% of the deformation between the structural layers.
