Round Bar Energy Dissipating Rod

Abstract

The invention discloses a round bar energy dissipation rod which comprises a core part, an outer constraint part and a positioning bolt. The core part is formed by connecting two energy dissipation sections, a middle limiting section and two-end connecting sections coaxially in the longitudinal direction. The middle limiting section is located between the two energy dissipation sections, and the two two-end connecting sections are located on the outer sides of a whole formed by the energy dissipation sections and the middle limiting section and are connected with a structure. The middle limiting section and the two-end connecting sections are all round bars, and a first hole is formed in the middle of the middle limiting section in the diameter direction. The energy dissipation sections are manufactured by cutting round bars in the length direction, so that the section of each energy dissipation section has two parallel opposite edges and two short edges which are arc lines, the area of the new section enables the energy dissipation sections to be buckled under the axial tension and pressure action on the core part, and the middle limiting section and the two-end connecting sections are always kept elastic.

Description

technical field [0001] The invention belongs to the field of civil engineering and relates to an energy dissipation rod used for reducing the seismic response of engineering structures. Background technique [0002] When cities and their buildings encounter strong earthquakes, not only will structural damage occur, but secondary disasters such as fires will also occur, which will trigger a series of chain disaster reactions. Based on this, the concept of energy dissipation and shock absorption proposed by the researchers aims to effectively reduce the seismic response of the structure by installing energy dissipation devices in the structure to absorb and dissipate energy, thereby avoiding serious damage to the main part of the structure. Mild steel damper is an energy-dissipating and shock-absorbing component with superior performance. It has been rapidly popularized and applied in developed countries such as Japan and the United States. However, the research and applicatio...

Problems solved by technology

[0005] The present invention solves the difficulty of setting concrete dense and unbonded materials in the buckling restraint support of the steel and concrete combined restraint component and the influence on performance, and the core component of the bamboo buckling restraint support is effective due to the setting of the circular elastic section The length of the yield energy dissipation section is reduced and the longitudinal weakening of the infinite section has the problems of premature buckling of the energy dissipation section under compression. A new type of round bar energy dissipation bar with a finite section is proposed.
