Low-yield-point steel energy consumption and adhesion energy consumption damper

Abstract

The invention relates to a low-yield-point steel energy consumption and adhesion energy consumption damper which comprises an upper connection plate and a lower connection plate which are oppositely arranged, a plurality of transverse energy consumption plates fixedly arranged between the upper connection plate and the lower connection plate, vertical surrounding and protecting plates which are fixedly arranged on the lower connection plate, are arranged on two sides of the transverse energy consumption plates in a blocking manner and form cavities with every two adjacent transverse energy consumption plates, cover plates covering the cavities, viscous fluid filling the cavities, and adhesion energy consumption steel plates fixedly arranged on the upper connection plate, wherein the bottoms of the adhesion energy consumption steel plates are arranged on the cover plates in a penetrating manner and are arranged in the corresponding cavities. The damper disclosed by the invention has two energy consumption modes, i.e. low-yield-point steel energy consumption and adhesion energy consumption; under the action of minor shock, an energy consumption plate is yielded, and the minor-shock yielding of the energy consumption plate is compensated by taking adhesion energy consumption measures; and the problem of reduction of the energy consumption property under moderate shock and large shock due to early development of a metal damper under the minor shock is solved.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a low yield point steel energy dissipation and viscous energy dissipation damper. Background technique [0002] The metal damper is a kind of building energy dissipation shock (vibration) device with superior energy dissipation performance and simple structure. The purpose of shock absorption. The advantages of the metal damper include: stable hysteretic energy dissipation performance, good low-cycle fatigue characteristics, simple structure, low cost, not affected by the environment, and obvious energy dissipation performance. [0003] Low yield point steel refers to steel with a yield strength between 100Mpa and 235Mpa. Low yield point steel has low yield strength, strong deformation ability, and good plastic energy dissipation performance. The damper is made of steel with a low yield point. Under the action of earthquake and wind vibration, the metal energy-d...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the defects of the prior art, provide a low-yield point steel energy dissipation and viscous energy dissipation damper, and solve the problem that the design yield displacement of the metal damper in the prior art is too large under moderate earthquakes. The damper has not yet yielded and does not play a role in consumption and shock absorption, and the yield displacement of the metal damper is small, which leads to the energy dissipation of the damper under the action of small earthquakes and wind vibrations, which makes the energy dissipation capacity play out prematurely and reduces the medium. The problem of energy dissipation performance under earthquake and large earthquake
