Therefore, the utility model can obtain a more uniform stress field distribution, and the shear plate enters into yield more uniformly, so as to give full play to the advantages of low yield and high ductility, and better play the role of energy consumption.
Description
Technical field
The utility model relates to a kind of metal sheet slitting surrender type damper, the rotational shear plate damper that particularly a kind of band is exerted oneself and supported, 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 a kind of 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.Because steel plate flexing makes hysteresis loop, produce Draw shrinkage, restricted the energy dissipation capacity of damper, also make the hysteretic behavior of damper more complicated.
Utility model content
Complicated in order to overcome traditional shear plate damper stress field, 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 plate damper that the utility model provides a kind of band to exert oneself and support, can improve the stressed force distribution of traditional shear plate 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.
the utility model solves the conception plans that its technical problem adopts:
Design the rotational shear plate damper that a kind of band is exerted oneself and supported, as shown in Fig. 1 ~ 6, damper is mainly by consisting of 6 parts: annular shear plate (1) as shown in Figure 2; Support (3), as shown in Figure 4; Bearing pin (3), as shown in Figure 3; What inner core (4) and turning arm (5), consist of is with cylindrical turning arm, as shown in Figure 5; With the pedestal (6) of circular hole, as shown in Figure 6.
Thereby the rotation of supporting drive turning arm makes inner core (4) produce rotation with respect to the pedestal with circular hole (6), annular shear plate (1) is sheared. because the fringe conditions of annular shear plate (1) is full symmetric, therefore can obtain more uniform Stress Field Distribution, shear plate enters surrender more uniformly, thereby give 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:
The rotational shear plate damper that band is exerted oneself and supported, comprises support, annular shear plate and pedestal, and specific features is: one end of described support and building framework are hinged, and slides and be rotationally connected in one end of the other end and two turning arms; The other end of described two turning arms has circular hole fixedly sleeved with the two ends of an inner core respectively; The middle part of described inner core and the endoporus of described annular shear plate are fixedly sleeved; The cylindrical border of described annular shear plate and the endoporus of described pedestal are fixedly sleeved, and pedestal is fixedly connected with building framework.
Described two turning arms are the mounting hole consisting of two arc-shaped edges and two straight lines with supporting the contact hole being rotationally connected that slides, and are rotatably assorted with a pin slide.
One section of described support has two axially extended lugs, and this lug has two circular holes and described bearing pin close-fitting; The other end supporting has the lug of two extensions equally, same and the hole close-fitting of even bearing pin with this two lug, realize and building frame hinged.
compared with prior art of the present utility model, there is following apparent substantive distinguishing features and a little:
1,, under geological process, new damper can fully absorb seismic energy by metal hysteretic energy;
2, the mode by rotational shear makes the annular slab of active section be subject to shear action, and this force way can be realized multiple mounting means flexibly, extenuates the conflicting request of building structure Lateral Resistant System and building function.
