Along with rapid development of bridge engineering technology and large building structures, particularly development and application of research achievements in the fields of wind resistance and earthquake resistance and new materials and new processes, the development of large-span cable-stayed bridges, suspended girder bridges, large gymnasiums, airport terminal buildings and high-rise buildings is promoted. Particularly, the rapid development of shock-resistant and shock-insulating metal yielding dampers and the like is widely applied in the field of engineering structures.
The existing earthquake-proof and wind-proof structure, such as patent 202110247587.6, provides a double-letter type supporting energy-consuming structure. When an earthquake occurs, the acting force generated during the displacement of the supporting frame system can be directly converted into the axial force of the horizontal connecting rod and transmitted to the damping component for dissipation and absorption. The frame system has the advantages that the bearing direction of the frame system is mainly in the plumb direction, the displacement action energy in the plumb direction is stronger during an earthquake, and the effect of the structure on absorbing energy in the plumb is poor, so that the energy eliminating effect is poor.
Disclosure of utility model
In order to overcome the problems in the background art, the utility model provides the herringbone supporting energy consumption structure, which can absorb structural displacement energy in the plumb direction by arranging the viscous damper in the horizontal direction for dissipation and arranging the buckling support in the plumb direction.
In order to solve the problems, the utility model is realized by the following technical scheme: the first support and the second support are both yieldable support members, each support member is provided with a core unit and a peripheral constraint unit, and the peripheral constraint units on opposite sides of the first support and the second support are respectively provided with a first damper and a second damper;
The first damper is connected with the second damper through a connecting piece, and at least one end of the first damper is hinged with at least one end of the second damper;
the connecting piece is fixedly connected to the lower ends of the first support and the second support respectively through symmetrical diagonal braces;
Further, the inner core units of the first support and the second support are yieldable steel cores, the steel cores are used as main supporting members of the cross beam, and the upper ends of the steel cores are connected with the cross beam; the peripheral constraint unit is a steel sleeve, concrete is poured between the steel sleeve and the steel core, and a non-adhesive material layer is arranged between the concrete and the steel core;
Further, connecting lugs are arranged on opposite sides of the steel sleeves of the first support and the second support, the connecting lugs are hinged with one ends of the first damper and the second damper, and the other ends of the first damper and the second damper are respectively and rigidly connected with two ends of the connecting piece;
Further, opposite sides of the steel sleeve of the first support and the steel sleeve of the second support are rigidly connected with one ends of the first damper and the second damper, and the other ends of the first damper and the second damper are respectively hinged with two ends of the connecting piece.
The beneficial effects of the utility model are as follows: the utility model dissipates the energy of the horizontal displacement of the frame by arranging a horizontal viscous damper between two support columns of the cross beam. The two support columns arranged in the plumb direction are buckling support members, and can absorb structural displacement energy in the plumb direction, so that energy generated by displacement or deformation of the frame system in the plumb direction is absorbed. Thus, damage to the frame system during earthquake resistance can be reduced.

Buckling of the steel core 203 is suppressed when pressed, and the axial pull and axial pressure of the buckling restrained brace are substantially the same, and their performance is mainly determined by their materials and cross-sectional areas. The plastic section loading cycle of the steel core 203 needs to reach 30 weeks.

Therefore, the beam structure is arranged in the plumb direction, can absorb energy generated after the beam 1 is displaced in the plumb direction, and avoids serious damage to the beam structure system.
