Energy-dissipating steel bars and concrete energy-dissipating structures having the same

Abstract

The invention discloses an energy dissipation steel bar and a concrete energy dissipation structure with the same. The energy dissipation steel bar comprises a steel bar body, and one or two connecting sections, a weakening structure for reducing the strength of the steel bar body is arranged on the steel bar body so that at least one part of the steel bar body can form an energy dissipation section; the one or two connecting sections are arranged at one or two ends of the steel bar body, the connecting sections and the steel bar body are coaxially arranged, and the strength of the energy dissipation section is smaller than that of the portion, where no energy dissipation section is formed, of the steel bar body and that of the connecting sections. According to the energy dissipation steel bar, the energy dissipation capacity is high, the deformation capacity is high, the anti-seismic property of the structure can be improved, and the damage to the main structure can be reduced.

Description

Technical field [0001] The present invention relates to the technical field of energy dissipation and shock absorption of civil engineering structures, and more specifically, to a civil engineering structure energy dissipation and shock absorption. Background technique [0002] Traditional structures dissipate energy and resist earthquakes through ductile deformation of nodes. For example, structural systems such as steel frames, reinforced concrete frames, reinforced concrete shear walls, etc., after an earthquake, large plastic deformations often occur at the structural nodes, the concrete is crushed, the steel bars are compressed and buckled, and the damage is serious, which increases the cost and difficulty of repair . Summary of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes an energy-consuming steel rod, which has strong energy-consumin...

[0002] Traditional structures use ductile deformation of joints to dissipate energy and resist earthquakes

For example, structural systems such as steel frames, reinforced concrete frames, and reinforced concrete shear walls, often have large plastic deformations at structural nodes after earthquakes, concrete collapse, steel bars buckling under compression, and serious damage, which increases the cost and difficulty of repair.
