Abstract
The utility model relates to a rotary shearing plate damper with a power outlet base, and belongs to the field of passive control in structure vibration control. The rotary shearing plate damper with the power outlet base can reduce the damage to a building structure from vibration through hysteretic energy consumption of metal. The rotary shearing plate damper with the power outlet base comprises the power outlet base formed by fixedly connecting a power outlet rod and a triangular base, a base with a round hole, and a rotary arm with an inner barrel, wherein the rotary arm with the inner barrel is formed by fixedly connecting a cylinder and a bored rotary arm, a hole of the bored rotary arm is movably matched with the power outlet rod in a sleeved mode, the inner barrel of the cylinder is fastened and matched with the inner circle boundary of an annular shearing plate, and the outer circle boundary of the annular shearing plate is fastened and matched with the round hole of the base. When the bored rotary arm drives the inner barrel and the base with the round hole to rotate in the opposite directions, the annular shearing plate deforms in a pure shearing mode. The annular shearing plate serving as a working section of the damper generates plastic deformation in the deformation process, and therefore seismic energy is consumed. The stress of the annular shearing plate is distributed evenly, the low-yielding high-ductility advantage is brought into full play, and the function of energy consumption is better played.
Description
Technical field
The utility model relates to a kind of metal sheet slitting surrender type damper, particularly a kind of band rotational shear plate damper of pedestal of exerting oneself, belong to the Passive Control category in structural vibration control, by the hysteretic energy of metal, reduce the damage that vibration brings to building structure.
Background technology
At present, structural vibration control is as a kind of important shock absorbing 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 the one of metal damper, utilizes the shear yielding dissipation seismic energy of metal.But traditional shear plate damper, because stress distribution is inhomogeneous, is difficult to predict that it destroys form, and stress such as concentrates also to have restricted the performance of its good ductility performance at the phenomenon.Produce Draw shrinkage because steel plate flexing makes hysteresis loop, restricted the energy dissipation capacity of damper, also make the hysteretic behavior of damper more complicated.
Utility model content
The object of the invention is to overcome traditional shear plate damper stress field complexity, the ductile performance of low-yield steel this shortcoming of can not being fully used, and in order to alleviate Draw shrinkage, the rotational shear steel plate damper that provides a kind of band to exert oneself pedestal, can improve the stressed force distribution of damper, thereby make damper obtain better ductile performance, simultaneously because stress field is relatively simple, its mechanical behavior also has predictability.And its mounting means is more flexible, can adapts to the convenient of more occasions and install.
for achieving the above object, design of the present utility model:the utility model is a kind of On A Retrofitted Damper---be with the rotational shear plate damper of the pedestal of exerting oneself.As shown in Fig. 1 to 5, damper is mainly made up of six parts: the pedestal of exerting oneself being formed by the bar of exerting oneself (1) and triangular base (2), as shown in Figure 2; The band inner cylinder rotating arm being formed by cylinder inner core (4) and perforate turning arm (3), as shown in Figure 3; Open the pedestal (5) of circular hole as shown in Figure 5; Annular shear plate (6); As shown in Figure 4.
When perforate turning arm (3) drives inner core (4), with the pedestal (5) of opening circular hole, rightabout rotation occurs, make annular shear plate (6) that pure shear distortion occur.As the shear plate (6) of damper active section thus in deformation process, produce plastic strain earthquake energy.Because the fringe conditions of annular shear plate (6) is full symmetric, therefore can obtain more uniform Stress Field Distribution, shear plate enters surrender more uniformly, thereby gives full play to the high ductility advantage of low surrender, better the effect of performance power consumption.In addition, therefore the form that adopts rotation due to new damper, can be designed and the different mounting means of damper in the past, flexible for installation and attractive in appearance.
according to above-mentioned utility model design, the utility model adopts following technical proposals:
A kind of rotational shear plate damper of tape handling pedestal, comprise that exert oneself pedestal and who is solidly fixed by exert oneself bar and triangular base opens round-meshed pedestal, it is characterized in that: have a band inner cylinder rotating arm being solidly fixed by cylinder and perforate turning arm, the perforate of its perforate turning arm is joined with the bar movable sleeve of exerting oneself; And that the inner circle border of its cylinder inner core and an annular shear plate tightens up is supporting, the cylindrical border of this annular shear plate and the circular hole fixed sleeve of pedestal are joined.
Described annular shear plate is equal thickness plate; Or annular shear plate is equal thickness not: thicker near inner circle border, and thinner near cylindrical border.
Described turning arm is mounting hole with the supporting perforation of activity of the bar of exerting oneself.
the utility model compared with prior art, has following apparent substantive distinguishing features and advantage:
1, rotational shear plate damper can pass through the abundant absorbing structure vibrational energy of hysteretic energy;
2, make the annular slab of active section be subject to shear action by the mode of rotational shear, this force way can be realized more flexibly and mounting means easily, extenuates conflicting of building structure Lateral Resistant System and building function.

The specific embodiment
Preferred embodiment accompanying drawings of the present utility model is as follows:
embodiment mono-:
As shown in Figure 1, the exert oneself rotational shear plate damper of pedestal of this band, comprise that exert oneself pedestal and who is solidly fixed by the bar of exerting oneself (1) and triangular base (2) opens round-meshed pedestal (5), it is characterized in that: have a band inner cylinder rotating arm being solidly fixed by cylinder (4) and perforate turning arm (3), the perforate of its perforate turning arm (3) is joined with bar (1) movable sleeve of exerting oneself; And that the inner circle border of its cylinder inner core (4) and an annular shear plate (6) tightens up is supporting, the circular hole fixed sleeve of the cylindrical border of this annular shear plate (6) and pedestal (5) is joined.When perforate turning arm (3) drives inner core (4), with the pedestal (5) of opening circular hole, rightabout rotation occurs, make annular shear plate (6) that pure shear distortion occur.As the annular shear plate (6) of damper active section thus in deformation process, producing plastic strain consumes vibrational energy.
embodiment two:
This example is basic identical with example one, but has following characteristics:
Annular shear plate (6) adopts the not design of equal thickness plate, thicker with the position that cylinder inner core (2) is connected, thinner with the position that the pedestal (5) of opening circular hole is connected, as shown in Figure 6.Thereby can be in the time rotating shearing, whole annular shear plate enters yield situation more uniformly, better brings into play ductility.
