Frame-shear piezoelectric friction damping device

Abstract

The invention discloses a frame-shear piezoelectric friction damping device. The frame-shear piezoelectric friction damping device comprises a frame and four friction damping devices, wherein the frame adopts a rectangular frame structure, and comprises four steel plates which are connected end to end; connecting parts are arranged at both ends of the steel plates respectively; through slots are formed in the connecting parts; the through slots in the connecting parts of the two adjacent steel plates correspond to each other, and are connected through the friction damping devices; the friction damping devices can slide along the through slots; each friction damping device comprises a bolt, and a friction damping pad, a stacked piezoelectric sheet stack and a nut which sequentially sleeve the screw of the bolt. Sizes of the steel plates can be adjusted to be consistent with sizes of used beam columns, so that the construction speed is high and the efficiency is high; a solar cell is used, so that power consumption is low, a high-voltage power supply is not required to be mounted, and detachment, replacement and installation of the solar cell and the stacked piezoelectric sheet stack are simple and feasible; due to four-point friction, energy consumption effect is relatively good.

Description

technical field [0001] The invention relates to the field of shock absorption control of a frame structure, in particular to a frame structure shear type piezoelectric friction damping device. Background technique [0002] At present, the commonly used frame structures are mostly X-type and T-type devices. The X-type device is a peripheral frame structure, and then connected with the middle friction damper through four struts to form an X-type device, such as figure 1 As shown; the T-shaped device is connected with the frame by a T-shaped core plate, and the T-shaped core plate is respectively connected with the left, right and lower steel plates of the frame, and a friction damper is installed at the connection with the lower part, such as figure 2 shown. Although the energy consumption effect of the device can meet the requirements, there are defects that affect the architectural shape and use function. Doors and windows cannot be installed at the location of the device,...
