Vertical Bamboo Shaped Round Rod Energy Dissipating Rod

Abstract

The invention discloses a vertical bamboo-shaped round bar energy-dissipating rod, which includes a core component, an outer constraint component and positioning pins; The connection sections at both ends are connected along the longitudinal coaxial line, the middle limiting section is located in the middle of the core component, the bamboo section and the energy dissipation section are arranged at intervals, arranged on both sides of the middle limiting section, and jointly formed with the middle limiting section As a whole, the outer two ends are fixedly connected to the connecting sections at both ends to jointly form the core component; the cross-sections of the middle limiting section, the bamboo section and the connecting sections at both ends are all circular, and the middle of the middle limiting section is opened along the diameter direction 1. The energy dissipation section is cut along the length direction so that the section of the energy dissipation section is two parallel opposite sides, and the other two short sides are original arcs. The new cross-sectional area formed allows the core component to enter the energy dissipation section under the action of axial tension and pressure. Yield, while the middle limit section, the bamboo section and the connecting sections at both ends remain elastic all the time.

Description

technical field [0001] The invention belongs to the field of civil engineering and relates to a buckling constraint support 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 application...
