Tri-linear shape in-plane bending yielding type energy dissipater and manufacturing method therefor

Abstract

The invention relates to a tri-linear shape in-plane bending yielding type energy dissipater and a manufacturing method therefor. The energy dissipater comprises a top plate, energy-consuming steel plates, a bottom plate and a connecting plate, wherein the energy-consuming steel plates are arranged between the top plate and the bottom plate; the connecting plate is arranged on the lower bottom surface of the bottom plate; and each energy-consuming steel plate consists of a plurality of steel columns with tri-linear shapes, which are arranged in a plane. According to the tri-linear shape in-plane bending yielding type energy dissipater, sufficient initial rigidity can be provided when small earthquake acts, and energy input by the earthquake can be consumed when major earthquake acts; the energy-consuming steel plates adopt the tri-linear shapes for transition, so that the stress redistribution is caused, the stress concentration of the in-plane yielding type energy dissipater is effectively improved, the multi-point yielding is realized, and the plastic deformability and low-cycle fatigue performance of the energy dissipater are enhanced. The energy dissipater is wide in application prospect and can be applied to reinforcement and reconstruction of new buildings and existing buildings.

Description

technical field [0001] The invention belongs to the energy dissipation shock absorption and vibration control technology of engineering structures, and relates to an in-plane bending yield type energy dissipation device with a three-fold line shape and a manufacturing method thereof. Background technique [0002] The traditional anti-seismic design is to resist earthquake action by enhancing the anti-seismic performance of the structure itself, that is, using the structure itself to store and consume seismic energy to meet the anti-seismic fortification goals of the structure: small earthquakes can not be damaged, moderate earthquakes can be repaired, and large earthquakes can not collapse. However, this anti-seismic method lacks the ability of self-regulation, and may not meet the requirements of structural safety under uncertain earthquake action. With the development of anti-seismic technology of building structures and the in-depth analysis of anti-seismic mechanism, ene...
