'5 + 4' orthogonal viscoelastic damping device
Technical Field
The invention relates to the technical field of civil engineering building structure energy dissipation and shock absorption, in particular to a 5+4 orthogonal viscoelastic damping device which can be applied to a vertical member of a building so as to effectively control wind vibration and earthquake response at a building node.
Background
The energy dissipation and shock absorption of the building structure means that a specially-made energy dissipation component or device is arranged in the building structure to increase the structural damping, so that when the building is subjected to earthquake motion, the energy input into the building structure system by the earthquake motion is absorbed and consumed to protect the safety of the main structure. In the field of civil engineering, viscoelastic damping devices are known as one of the most effective passive control devices in terms of wind resistance and vibration resistance, can exert vibration control effects without large relative deformation, and can be applied to both seismic response and wind vibration control of structures.
The viscoelastic damper commonly used at present is generally formed by combining three layers of steel plates and two layers of viscoelastic material layers, wherein the middle steel plate is connected with a beam in the structure through a connecting piece, and the side steel plates are connected with the beam on the other layer in the structure through the connecting piece. When the structure is subjected to wind load or earthquake action, relative displacement occurs between structural layers, the inner steel plate and the outer steel plate move relatively to drive the viscoelastic material to generate reciprocating shear deformation, and the vibration of the structure under the wind load or earthquake action is reduced and rapidly attenuated by utilizing the characteristic that the strain of the viscoelastic material lags behind the stress, so that the aims of dissipating energy and absorbing shock are fulfilled. However, existing viscoelastic damper designs are not suitable for use with vertical members in building structures. Therefore, the improvement of the structural design of the viscoelastic damper has important significance for the application and popularization of the damper.

Aiming at the problems that the conventional viscoelastic damper cannot be arranged at a vertical component of a building and can better exert the energy consumption effect of a viscoelastic material, the method provides an effective solution and effectively improves the vibration resistance of a node of the building.
The technical scheme adopted by the invention is as follows:
the utility model provides a "5 + 4" quadrature type viscoelastic damping device, includes 5 layers of steel sheet and 4 layers of viscoelastic material, its characterized in that: the viscoelastic material layer is vulcanized and bonded between the two side steel plates, and the middle steel plate and the four side constraint steel plates are in a 90-degree vertical state.
Furthermore, wherein the viscoelastic material layer is high damping rubber polymer, the thickness of each layer of viscoelastic material is 10mm, the thickness of the middle steel plate is 20mm, the thickness of the four constraint steel plates on two sides is 12mm, and the size of the viscoelastic material layer is the same as that of the two constraint steel plates on the inner side.
The viscoelastic material layer and the steel plate are alternately formed, and the outermost side is the steel plate.
Two blocks of steel sheets in the outermost side are arranged in an up-and-down symmetrical mode, and bolt holes with the diameter of 24mm are formed in the end portion of the middle steel sheet and the end portions of the two restraint steel sheets in the outermost side, so that the device and the structure can be conveniently connected.
The use method of the '5 + 4' orthogonal viscoelastic damping device is characterized in that: viscoelastic damping means are arranged at the vertical elements between the floors of the building, the first case: the extending sides of the two restraining steel plates are connected with the cross beams between layers through connecting pieces, and the extending side of the middle steel plate is connected with the columns between layers through connecting pieces. In the second case: the extending sides of the two restraining steel plates are connected with the longitudinal beams between layers through connecting pieces, and the extending side of the middle steel plate is connected with the columns between layers through connecting pieces. In the third case: the extending sides of the two restraining steel plates are connected with the horizontal (longitudinal) beam between layers through connecting pieces, and the extending side of the middle steel plate is connected with the vertical (horizontal) beam between layers through connecting pieces.
Compared with the prior art, the 5+4 orthogonal viscoelastic damping device has the advantages that the 5+4 orthogonal viscoelastic damping device can be arranged at the vertical members of a building structure, such as beam-column joints and transverse-longitudinal beam joints, so that the anti-seismic performance of the building joints is effectively improved, and the structural safety of a building main body is guaranteed.
