Problems solved by technology

It is difficult for the current damping wall technology to exert good energy dissipation and shock absorption / vibration effects at small relative displacements and speeds. The existing patents set up an additional amplification system to amplify the displacement transmitted from the structure to the damper to a certain extent. can solve this problem, but the overall efficiency is very low and unstable

Abstract

The invention provides a shear type damping wall with reverse displacement amplification. The shear type damping wall comprises an upper connecting plate, at least one displacement amplification mechanism and a lower connecting plate, wherein the upper connecting plate is arranged on an upper floor beam, and at least two fixed shear plates are arranged on the lower surface of the upper connecting plate; and the displacement amplification mechanisms are arranged in a damper outer steel box, each displacement amplification mechanism is located between the two fixed shear plates, the upper ends of the displacement amplification mechanisms are hinged to the upper ends of the fixed shear plates through first rotating shafts, and the damper outer steel box is filled with shear energy dissipation materials. The shear type damping wall with reverse displacement amplification is simple in structure, when the upper floor beam moves horizontally, interlayer displacement acts on reverse shear plates through displacement amplification levers, the reverse shear plates and the fixed shear plates move reversely to shear the shear energy dissipation materials in the damper outer steel box, so that the relative displacement and speed of the damping wall are increased, and the energy consumption of the damping wall is improved.

Description

technical field [0001] The invention relates to the technical field of energy dissipation and shock absorption for building structures, in particular to a shear type damping wall with reversely amplified displacement. Background technique [0002] As a kind of energy-dissipating and shock-absorbing device, damping wall is widely used in new construction and seismic reinforcement projects because of its stable hysteretic energy consumption and effective control of the dynamic response of structures. It is difficult for the current damping wall technology to exert good energy dissipation and shock absorption / vibration effects at small relative displacements and speeds. The existing patents set up an additional amplification system to amplify the displacement transmitted from the structure to the damper to a certain extent. The above can solve this problem, but the overall efficiency is very low and unstable. Contents of the invention [0003] In order to solve the above pro...
