Multi-point yield energy dissipating type mild steel energy dissipater

Abstract

The invention relates to a multi-point yield energy dissipating type mild steel energy dissipater. The multi-point yield energy dissipating type mild steel energy dissipater mainly comprises a top plate, an energy dissipating plate, a bottom plate and a connecting plate, wherein the energy dissipating plate is arranged between the top plate and the bottom plate; the connecting plate is arranged on the lower surface of the bottom plate; the energy dissipating plate is formed by arranging a plurality of energy dissipating units in an in-plane manner. The multi-point yield energy dissipating type mild steel energy dissipater has the advantages that by adopting the in-plane bending yield stress type, the enough initial rigidity is provided under the action of small earthquake, the energy inputted by the earthquake is dissipated under the action of large earthquake, and a main body structure is protected; each energy dissipating unit is in a symmetric circular arc shape, a plurality of plastic yield points can be formed under the action of the earthquake, the stress is redistributed, the stress concentration effect is effectively improved, and the plastic deformation capability and low-cycle fatigue property are improved; the ductility is good, the structure is simple, the replacement is convenient, the energy dissipating property is good, and an excellent energy dissipating and earthquake-proof member is provided.

Description

Technical field [0001] The invention relates to a multi-point yield energy-consuming mild steel energy dissipator, which belongs to the technical field of energy dissipation and shock absorption of building structures. Background technique [0002] Traditional seismic design is to resist earthquake effects by enhancing the seismic performance of the structure itself, that is, using the structure itself to store and consume seismic energy to meet the structural seismic fortification goals: small earthquakes are not damaged, moderate earthquakes can be repaired, and large earthquakes are not collapsed. However, this anti-seismic method lacks the ability of self-adjustment, and under the action of uncertain earthquake, it may not meet the requirements of structural safety. [0003] After decades of development, the theory of energy dissipation and shock absorption and its corresponding energy dissipation devices have matured day by day. Various forms of energy dissipation devices have...
