Maintainable buckling-restrained energy dissipation supporting device

Abstract

The invention relates to the technical field of civil engineering structures, in particular to a maintainable buckling-restrained energy dissipation supporting device. The maintainable buckling-restrained energy dissipation supporting device comprises an external restraint system and a core energy dissipation steel plate, and the external restraint system forms a cavity structure for preventing the core energy dissipation steel plate from buckling and installing the core energy dissipation steel plate. According to the maintainable buckling-restrained energy dissipation supporting device, thecavity structure for preventing the core energy dissipation steel plate from buckling and installing the core energy dissipation steel plate is formed through the external restraint system, buckling of the core energy dissipation steel plate can be comprehensively prevented, and the complete anti-buckling energy dissipation supporting device is formed. Meanwhile, the maintainable buckling-restrained energy dissipation supporting structure is simple in form and stable in stress performance, the core energy dissipation steel plate can be conveniently disassembled and replaced after being stressed, yielded and damaged, so that maintenance of the buckling-restrained supporting is achieved, and the maintainable buckling-restrained energy dissipation supporting device has good generalization performance.

Description

technical field [0001] The invention relates to the technical field of civil engineering structures, in particular to a maintainable anti-buckling energy dissipation support device. Background technique [0002] Natural disasters such as earthquakes are unpredictable and destructive. my country is an earthquake-prone country, and earthquakes cause huge economic losses and casualties every year. Improving the ability of buildings and structures to resist natural disasters such as earthquakes and strong winds is one of the important research directions of civil engineering disciplines. The use of energy dissipation damping elements to dissipate the energy of external input structures is more and more widely used in structural disaster prevention and mitigation, etc. aspect. Buckling-resistant braces are energy-dissipating and shock-absorbing components widely used in structures such as buildings and bridges. Under moderate and small earthquakes, the anti-buckling brace can p...

Problems solved by technology

[0003] At present, the anti-buckling braces used in the fields of buildings and bridges have large structural size and high cost. After the structure suffers a large earthquake, the anti-buckling braces are basically damaged and need to be replaced, which brings a lot of manpower, material and financial losses. Complicated repair procedures and long repair cycles seriously affect the reuse of building structures
