Description
Technical Field
The invention relates to the technical field of energy consumption components of building structures, in particular to an efficiency amplification type rotary friction coupling beam damper.
Background
The frame-shear wall and the frame core tube structure are widely applied to high-rise and super-high-rise structures due to good lateral rigidity, and the connecting beams are taken as important components for connecting the walls and limbs of the shear wall and are generally designed into a first anti-seismic defense line, so that the connecting beams are bent before the walls and limbs through reasonable design, and the seismic energy is dissipated. From the view of structural vibration control, the connecting beam has the characteristics of large deformation and definite stress mechanism, and is an ideal position for installing the additional damper.
The friction type 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 continuous beam dampers are used for carrying out friction energy consumption by means of relative vertical displacement generated by members. According to classical coulomb friction theory, if the bearing capacity of the friction coupling beam damper is required to be improved, the friction coefficient of the friction plate or the pre-pressure of the bolt can be improved. However, due to the limitation of materials, the friction coefficient of the friction plate is improved only to a limited extent, and the increase of the pre-pressure of the bolt can cause the increase of the pre-pressure loss of the friction beam-connecting damper in the non-working and working processes, and the excessive pre-pressure can even cause the excessive local compression deformation of the damper member, so that the friction beam-connecting 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 continuous 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 precompression 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 shaft 5 or the right pin shaft 6, so that the precompression loss of the high-strength bolt 12 in a non-working state and a working state is effectively reduced; in the case that the damping coefficient 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 shaft 5 or the right pin shaft 6.
The reason why 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 to improve the bearing capacity of the continuous beam damper is that: according to coulomb friction theorem f=μn, 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 when the single first friction plate 8, the second friction plate 9, the third friction plate 10 or the fourth friction plate 11 rotates 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 rotation deformation, a larger vertical force needs to be provided at the end parts of the left connecting end plate 1 and the right connecting end plate 2 to overcome the rotation bending moment M generated by the friction force, namely the improvement of the bearing capacity of the damper is reflected.
The reason why the energy consumption capability of the continuous 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 the action of an earthquake can be expressed in terms of 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 for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
