Embodiment 1

[0024] When the present invention adopts the middle column type to be installed in the building structure, such as Figure 4 As shown, several wall-type mild steel bending energy dissipation dampers are combined and installed in the load-bearing structure of the building structure. The upper part of the inner steel plate 1 of the wall-type mild steel bending energy dissipation damper is connected with the upper beam of the building structure through high-strength bolts, and the lower part of the outer steel plate 2 of the wall-type mild steel bending energy dissipation damper is connected with the load-bearing platform of the building structure through high-strength bolts Fixed connection. When an earthquake occurs, the relative displacement of the inner steel plate 1 and the outer steel plate 2 will drive the mild steel energy-dissipating steel plate 3 to achieve full-section plastic yield, absorb the energy input by the earthquake, and finally achieve the purpose of attenuat...

Abstract

The invention discloses a wall type soft steel bending energy-consumption damper, which consists of an inner steel plate (1), two outer steel plates (2), a soft energy-consumption steel sheet (3) and a sleeve hoop member (4), wherein the plate surfaces of the inner steel plate (1) and the outer steel plates (2) are in hollow forms, and the outer steel plates (2) are positioned at both sides of the inner steel plate (1) and are in relatively parallel arrangement; and the middle part of the soft energy-consumption steel sheet (3) is vertically embedded in the hollow part arranged on the inner steel plate (1), both ends of the soft energy-consumption steel sheet (3) are respectively and vertically embedded in the hollow parts of the outer steel plates (2) arranged at both sides of the inner steel plate (1), and parts of both ends of the soft steel energy-consumption steel sheet (3) extending out of the outer steel plates (2) are connected with the sleeve hoop member (4). The wall type integral structure of the invention solves the problem of compression instability easily generated by the traditional damper, has the characteristics of simple structure, clear stress, easy displacement and good building compatibility, and is applicable to engineering of newly building or modifying buildings in mid-rise and high-rise concrete or steel structures.

Description

technical field [0001] The invention belongs to the field of anti-seismic and shock-absorbing civil engineering, and in particular relates to a metal energy-dissipating damper in a structural shock-absorbing control system, specifically a wall-type soft steel bending energy that can increase structural damping and reduce structural response in earthquakes damper. Background technique [0002] Metal energy dissipation dampers use different forms of plastic hysteretic deformation of metals to dissipate energy. Because metal has good hysteresis characteristics after entering the plastic state, and absorbs a large amount of energy during the elastic-plastic hysteretic deformation process, it is used to manufacture energy-dissipating shock absorbers of different types and structures. From the force form, it can be divided into axial yield type, shear yield type, bending yield type and torsional yield type damper. Representative products that have been formed: X-shaped and tria...
