Description
Technical Field
The invention relates to the technical field of energy dissipation components of building structures, in particular to an efficiency-amplified type rotary friction coupling beam damper.
Background
The frame-shear wall and frame core tube structure is widely applied to high-rise and super high-rise structures due to good lateral stiffness, the connecting beam is used as an important component for connecting the shear wall limbs and is usually designed as a first anti-seismic defense line, and the connecting beam is enabled to yield before the wall limbs through reasonable design so as to dissipate seismic energy. From the structural vibration control perspective, the coupling beam has the characteristics of large deformation and clear stress mechanism, and is an ideal position for installing the additional damper.
The friction damper has the characteristics of full hysteresis curve, high initial rigidity, stable performance and the like, and is widely applied to vibration control of building structures. Most of the existing friction type coupling beam dampers perform friction energy dissipation through relative vertical displacement generated by components.

However, due to the limitation of materials, the friction coefficient of the friction plate is limited to be increased, and increasing the pre-pressure of the bolt can increase the pre-pressure loss of the friction coupling beam damper in the non-working and working processes, and even the excessive pre-pressure can cause the local compression deformation of the damper component to be too large, so that the friction coupling beam damper cannot work normally.

The efficiency amplification mechanism of the invention is as follows: according to the invention, the left connecting end plate 1 and the right connecting end plate 2 are vertically arranged on the shear wall 16, the left connecting end plate 1 and the right connecting end plate 2 drive the first transverse plate 3 and the second transverse plate 4 to rotate, rub and consume energy, and the bearing capacity of the connecting beam damper is improved by increasing the distance from the first friction plate 8, the second friction plate 9, the third friction plate 10 or the fourth friction plate 11 to the pin shaft. Under the same bearing capacity requirement, the pre-pressure applied by the high-strength bolt 12 can be properly reduced on the basis of increasing the distance from the first friction plate 8, the second friction plate 9, the third friction plate 10 or the fourth friction plate 11 to the left pin 5 or the right pin 6, and the loss of the pre-pressure of the high-strength bolt 12 in a non-working state and a working state is effectively reduced; under the condition that the damping coefficients of the first friction plate 8, the second friction plate 9, the third friction plate 10 or the fourth friction plate 11 and the pre-pressure of the high-strength bolt 12 are determined, the bearing capacity and the energy consumption capacity of the damper can be improved by increasing the distance from the first friction plate 8, the second friction plate 9, the third friction plate 10 or the fourth friction plate 11 to the left pin 5 or the right pin 6.
The reason why the bearing capacity of the coupling beam damper can be improved by increasing the distance from the first friction plate 8, the second friction plate 9, the third friction plate 10 or the fourth friction plate 11 to the left pin shaft 5 or the right pin shaft 6 is as follows: according to the coulomb friction theorem f = μ N, when the friction coefficient μ of the first friction plate 8, the second friction plate 9, the third friction plate 10 or the fourth friction plate 11 and the pretightening force N provided by the high-strength bolt 12 are fixed, the friction force f provided by the single first friction plate 8, the second friction plate 9, the third friction plate 10 or the fourth friction plate 11 when rotating is a fixed value, and according to the calculation formula M = fL of the bending moment, when the distance L from the first friction plate 8, the second friction plate 9, the third friction plate 10 or the fourth friction plate 11 to the left pin 5 or the right pin 6 is increased, in order to drive the first transverse plate 3 and the second transverse plate 4 to generate rotational deformation, a larger vertical force needs to be provided at the end portions of the left connecting end plate 1 and the right connecting end plate 2 to overcome the rotational bending moment M generated by the friction force, that is reflected as the improvement of the bearing capacity of the damper.
The reason why the energy consumption capability of the coupling beam damper can be improved by increasing the distance from the first friction plate 8, the second friction plate 9, the third friction plate 10 or the fourth friction plate 11 to the left pin shaft 5 or the right pin shaft 6 is as follows: the energy absorbed by the damper under seismic action can be represented by the area enclosed by the force-displacement curve. When the distance from the first friction plate 8, the second friction plate 9, the third friction plate 10 or the fourth friction plate 11 to the left pin shaft 5 or the right pin shaft 6 is increased, the bearing capacity of the damper is improved, the area surrounded by the force-displacement curve is increased, and the energy consumption capacity of the damper is improved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
