Abstract
The utility model relates to a kind of damper with composite corrugated sandwich shear plate, comprises overhead gage, lower baffle plate, front plate, rear plate and sandwich shear plate; Described front plate, the size of rear plate and sandwich shear plate is consistent, and front plate and rear plate are clipped in the middle sandwich shear plate fix, and forms sandwiched plate, described sandwich shear plate is corrugated sheet, sandwiched plate along the two ends up and down of ripple direction fixedly overhead gage and lower baffle plate.The damper of the composite corrugated sandwich shear plate of the utility model band has strengthened inplane stability, thereby make damper obtain better ductile performance, by sandwich, construct, increase the lateral deformation capacity of such shear plate, by obtaining larger plastic strain, improve the hysteretic energy ability of shear plate integral body.
Description
Technical field
The utility model relates to a kind of damper with composite corrugated sandwich shear plate.
Background technology
At present, structural vibration control is as a kind of important vibration damping means, and its application constantly increases.Compare other control devices, metal damper is as the category of structure Passive Control, the seismic energy that can dissipate when providing rigidity for structure, with its price relatively cheap be easy to realize obtain more application.Shear plate damper is a kind of of metal damper, utilizes the shear yielding dissipation seismic energy of metal.But traditional shear plate damper, easily there is the outer unstable phenomenon of plane in web, the ductile performance of low-yield steel can not be fully used, cause damper to fail fully to enter the power consumption stage, thereby cause the hysteretic energy curve of shear plate damper to pinch contracting, have a strong impact on the energy-dissipating property of shear plate damper.
Utility model content
The defect existing for prior art, the purpose of this utility model is to provide a kind of damper with composite corrugated sandwich shear plate, by the hysteretic energy of metal, reduces the damage that vibration brings to building structure.
For achieving the above object, the utility model adopts following technical scheme:
A damper with composite corrugated sandwich shear plate, comprises overhead gage, lower baffle plate, front plate, rear plate and sandwich shear plate; Described front plate, the size of rear plate and sandwich shear plate is consistent, and front plate and rear plate are clipped in the middle sandwich shear plate fix, and forms sandwiched plate, described sandwich shear plate is corrugated sheet, sandwiched plate along the two ends up and down of ripple direction fixedly overhead gage and lower baffle plate.
Further, the bellows-shaped of described sandwich shear plate is trapezoidal wave mode or sinusoidal waveform.
The beneficial effects of the utility model are:
The damper of the composite corrugated sandwich shear plate of the utility model band has strengthened inplane stability, thereby make damper obtain better ductile performance, by sandwich, construct, increase the lateral deformation capacity of such shear plate, by obtaining larger plastic strain, improve the hysteretic energy ability of shear plate integral body.

Fig. 2 is sandwiched plate schematic diagram of the present utility model.
Fig. 3 is sandwiched plate top view of the present utility model.
Fig. 4 is sandwich shear plate schematic diagram of the present utility model.
Fig. 5 is the schematic diagram of the position of the utility model in steel framed structure.
The specific embodiment
Preferred embodiment accompanying drawings of the present utility model is as follows:
embodiment mono-
As shown in Figures 1 to 4, a kind of damper with composite corrugated sandwich shear plate, comprises overhead gage 1, lower baffle plate 2, front plate 3, rear plate 4 and sandwich shear plate 5; Described front plate 3, rear plate 4 is consistent with the size of sandwich shear plate 5, front plate 3 and rear plate 4 are clipped in the middle sandwich shear plate 5 fix, and the sandwich shear plate 5 forming described in sandwiched plate is corrugated sheet, sandwiched plate along the two ends up and down of ripple direction fixedly overhead gage 1 and lower baffle plate 2.
The bellows-shaped of described sandwich shear plate 5 is trapezoidal wave mode.
As shown in Figure 5, damper is connected with framework by rod member, and is placed in frame center.When frame construction generation lateral displacement, by the relative displacement of upper underbeam, driven the shear displacemant of damper; Damper top is by Vierendeel girder Transfer of Shear, and bottom is by connecting rod Transfer of Shear, thereby carries out shear energy dissipation, because the structure of damper sandwiched plate is different, also has part bending energy-wasting.
embodiment bis-
The present embodiment and embodiment mono-are basic identical, and difference is, the bellows-shaped of described sandwich shear plate 5 is sinusoidal waveform.Sinusoidal waveform design reduces again the shear energy dissipation part of corrugated web, has increased the part of bending energy-wasting, has also reduced corrugated sheet lateral strength simultaneously, and whole sandwiched plate shear plate more easily enters the surrender power consumption stage, better brings into play ductility.
