Abstract

The invention discloses a modularized bamboo-shaped buckling restrained brace which comprises a core part, an outer restraining part and a structure connecting part. The core part comprises a plurality of circular energy dissipation sections and a plurality of elastic sleeves. Each circular energy dissipation section comprises a middle section and connecting sections at two ends. The core part is located inside the outer restraining part. The inner surface of the outer restraining part closely attaches to or is tangent to the outer surfaces of the elastic sleeves of the core part. One end of the structure connecting part extends into the outer restraining part, and the other end thereof extends out of the outer restraining part to be connected with a structure. The modularized bamboo-shaped buckling restrained brace has the advantages that the circular energy dissipation sections and elastic sleeves of the modularized bamboo-shaped buckling restrained brace can be produced in batch in factories, the circular energy dissipation sections and elastic sleeves can be selected and combined according to the length requirement of the buckling restrained brace, and accordingly the modularized production and design of the core part can be achieved.

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] Earthquake is one of the major natural disasters that cities and their buildings may suffer. Strong earthquakes not only cause structural damage, but also cause secondary disasters such as fires and chain effects. The concept of energy dissipation and shock absorption refers to absorbing and dissipating seismic energy through energy dissipation devices, effectively reducing the response and damage of the structure, and avoiding serious damage to the main structure. Buckling-restrained braces, as an energy-dissipating and shock-absorbing member with superior performance, have been rapidly popularized and applied in developed countries such as Japan and the United States, and their research and application in my country are also in their infancy. Buckling-restraine...
