Lattice box type mild steel damper

Abstract

A lattice box type mild steel damper is an energy dissipation and shock attenuation device mainly applied to the field of bridge and structural engineering. The lattice box type mild steel damper is formed by an upper connection steel plate, cover plates, hourglass-shaped mild steel plates and a lower connection steel plate. The transverse and longitudinal hourglass-shaped mild steel plates form a lattice structure with the lower portion connected with the lower connection steel plate and the upper portion connected with the upper connection steel plate through the cover plates. The lattice structure can be deformed inside and outside a plane at the same time by the aid of the hourglass-shaped mild steel plates, so that more energy can be absorbed and dissipated. The lattice box type mild steel damper has the advantages that seismic energy transmitted to structures can be partially dissipated by own deformation of the lattice box type mild steel damper, and accordingly main structures and critical components of bridges and buildings are protected from seismic damage, and structural deformation can be controlled reasonably; moreover, the lattice box type mild steel damper can be replaced quickly after earthquake.

Description

technical field [0001] The invention relates to an energy-dissipating shock-absorbing device in the field of bridge and structural engineering, in particular to a two-way energy-dissipating palace-style box-type mild steel damper. Background technique [0002] my country is located at the junction of the circum-Pacific seismic belt and the Eurasian seismic belt, and is an earthquake-prone country. In order to minimize the losses caused by earthquake disasters, it is necessary to carry out seismic design and reinforcement for engineering structures such as buildings and bridges. The traditional anti-seismic design is to use the deformation of the structure itself to resist and dissipate the seismic energy to meet the anti-seismic requirements of the structure. Structural shock absorption control technology is to add a specific energy-dissipating element to the structure. Under the action of an earthquake, the structure mainly relies on the specific energy-dissipating element...

AI Technical Summary

Problems solved by technology

[0003] Metal steel plate is a widely used energy-dissipating element. Its traditional structure and energy-dissipating mechanism mainly rely on the superposition of several steel plates. It can only deform in a single plane and out-of-plane. It cannot consider both in-plane and out-of-plane situation, so its energy efficiency is low

In addition, the ground motion is multi-directional, and the traditional metal plate damper cannot dissipate energy in two horizontal directions at the same time, and cannot achieve the effect and purpose of bidirectional energy consumption and shock absorption
