Description
Technical Field
The invention relates to an engineering structure system, in particular to a high-efficiency energy-dissipation and shock-absorption engineering structure system.
Background
The traditional horizontal earthquake-resistant method of the building engineering structure system is mainly used for resisting the earthquake action by enhancing the earthquake-resistant performance of the structure. However, people often cannot predict and estimate the actual strength and characteristics of the earthquake, and the rigidity of the structure cannot be designed to be infinite due to construction cost considerations and practical limitations. In order to reduce the seismic response of structures, energy-consuming and shock-absorbing technologies are used in more and more projects. The energy dissipation and shock absorption technology consumes energy transferred to a structure by an earthquake through an additional substructure or an energy dissipation device.
At present, scholars at home and abroad develop various energy dissipation and damping devices with different types and different structures, and due to the fact that the history of research and application of energy dissipation and damping technologies is short, in some engineering applications, such as reinforced concrete shear wall structures, steel support systems and wood frame structures, the energy dissipation devices cannot play a role or even cannot be started due to insufficient elastic displacement under small earthquakes.
Disclosure of Invention
The invention aims to solve the technical problem of providing an efficient energy-consuming and shock-absorbing engineering structure system, which can enable an energy-consuming device to play a role under the condition of small shock, effectively reduce the seismic response of the building engineering structure system and further improve the shock-absorbing effect.
The technical scheme adopted by the invention for solving the problems is as follows:
the utility model provides a high-efficient energy dissipation shock attenuation engineering structure system which characterized in that: a damper is arranged on a floor beam of the engineering structure system; the damper is flexibly connected to the upper floor beam or the lower floor beam which generates relative horizontal displacement relative to the floor beam and spans the floor through a flexible connector;
or:
a damper is arranged on the basis of the engineering structure system; the damper is flexibly connected to the upper floor beam which generates relative horizontal displacement relative to the foundation and spans the floor through a flexible connector.
Preferably, the flexible connector is a steel wire rope, a steel strand or other flexible ropes made of flexible materials, and the flexible connector is connected with the lower floor beam or the upper floor beam through a connecting piece.
Preferably, the damper is hinged and fixed on a floor beam, a foundation or a stress member such as a shear wall.
On the basis of the above, the invention has the following structural forms:
when the flexible rope is one, the flexible rope is vertically connected with the damper and the lower floor beam or the upper floor beam.
When the number of the flexible ropes is two, one end of each rope is connected with the damper, and the other end of each rope is separately connected with the upper floor beam or the lower floor beam.
When the number of the flexible ropes is four, the damper is connected to the holes of the upper floor beam and the middle floor beam between the upper floor beam and the lower floor beam in the spanning layer in a swinging mode from the middle, one end of each of the two flexible ropes is connected with one end of the damper, the other end of each of the two flexible ropes is separately connected with the upper floor beam, one end of each of the other two flexible ropes is connected with the other end of the damper, and the other end of each of the other two flexible ropes is separately connected with the lower floor beam.
The flexible rope converts the oblique displacement of the flexible connection into horizontal displacement through a pulley and/or guide rail connection conversion device and then is connected with the damper.
The damper is a viscoelastic damper, a viscous damper or an oil damper.
The number of the dampers is at least one.
The damper (2) is a linear, L or Z-shaped friction damper which can adopt bolt pre-tightening to enable the internal friction plate to provide friction energy consumption.
Further, the damper (2) can be a viscoelastic damper, a viscous damper or an oil damper through an additional connection conversion device.
Therefore, the relative displacement of the building acts on the damper through the floor beam and the flexible connection and through the cross-layer, so that the damper generates larger relative displacement, namely larger damping force.
The invention has the beneficial effects that:
the invention fixes the connecting piece on the floor beam, the near end of the flexible connection is connected with the connecting piece, the far end is connected with the damper, and the damper can be freely selected. The large-displacement floor is connected in a cross-layer mode through the damper, so that the damping force of the damper is amplified under the condition that the interlayer displacement of the damper is small, and the energy consumption effect is improved.

Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
Example one
Referring to fig. 1-5, in order to implement the first embodiment of the energy-consuming and shock-absorbing engineering structural system of the present invention, a damper 2 is pivotally hinged from the middle to a hole of a floor beam of the engineering structural system, and has upper and lower flexible connector connection points.
The damper 2 in this embodiment is a linear, L, or Z-shaped friction damper that can be pre-tightened with bolts to provide frictional energy to the internal friction plates.
The dampers 2 are flexibly connected via flexible connectors 1 via connectors 3 to the upper floor beams and to the lower floor beams, which are generating a relatively large horizontal displacement relative to the floor beam cross-layers.
The cross-layer in this embodiment may span 1 layer or multiple layers, as shown in fig. 5, and may be determined according to actual energy consumption requirements.
The flexible connector 1 in this embodiment is four steel cables, steel strands or other flexible ropes made of flexible materials. One end of two of the flexible ropes is connected with one flexible connector connecting point of the damper 2, the other end of the two flexible ropes is separately connected with the upper floor beam through a connecting piece 3, one end of the other two flexible ropes is connected with the other flexible connector connecting point of the damper, and the other end of the two flexible ropes is separately connected with the lower floor beam through a connecting piece.
It is emphasized that the present embodiment spans between the upper floor beams and the intermediate floor beams, and between the lower floor beams and the intermediate floor beams, either by one or more layers, except that the layers that span are not shown. The same applies to the figures of the following examples.
When the cross-layer upper floor beam and the cross-layer lower floor beam generate relatively large translation relative to the floor beam, large displacement can be transmitted to the damper through the flexible connection, so that the relative deformation of the damper is increased, larger damping force is generated, and more energy is consumed.
Example two
As shown in fig. 6, the second embodiment of the present invention is the same as the first embodiment except that the damper 2 is an "L" type damper.
EXAMPLE III
As shown in fig. 7, the third embodiment of the present invention is the same as the first embodiment except that the damper 2 is a "Z" type damper.
Example four
As shown in fig. 8, in the fourth embodiment of the present invention, the right hole of the damper 2 is fixed on the middle floor beam by bolt connection, the left hole is connected with one end of two flexible connecting ropes, the other end of the flexible connecting rope is connected with two connecting pieces 3 by pulleys, and the two connecting pieces 3 are separately and fixedly connected with the upper floor beam.
EXAMPLE five
As shown in fig. 9, in the fifth embodiment of the present invention, the damper 2 is fixed on the middle floor beam by bolt connection, the left hole of the damper 2 is connected with one end of a flexible connecting rope, the other end of the flexible connecting rope is connected with the connecting piece 3 by a pulley, and the connecting piece 3 is fixedly connected with the right side of the upper floor beam. The right hole of the damper 2 is connected with one end of another flexible connecting rope, the other end of the another flexible connecting rope is connected with a connecting piece 3 through a pulley, and the connecting piece 3 is fixedly connected with the left side of the lower floor beam. So that the two flexible connecting ropes are crossed.
For the fourth embodiment and the fifth embodiment, when the upper floor and the lower floor translate, the oblique displacement flexibly connected through the conversion devices such as the pulleys or the guide rails can be converted into the horizontal displacement of the damper, so that the relative deformation of the damper is increased, a larger damping force is generated, and more energy is consumed. The damper is a viscous damper, and can also be a viscoelastic damper, an oil damper and the like.
The damper can also be arranged in parallel.
As far as the flexible cord is one, it connects the damper vertically to the lower floor beam or to the upper floor beam. This is simpler and will not be described in detail.
