Abstract

A novel bolt transformed anti-buckling energy dissipation bracing comprises a core stress unit, a constraint unit and transforming devices, wherein the constraint unit is located on the periphery of the core stress unit, and the transforming devices are located at the two ends of the core stress unit. The core stress unit is a steel plate with a line-shaped cross section. The two ends of the core stress unit are provided with bolt holes respectively. The ends of the core stress unit are provided with core material compressing parts. Each transforming device comprises a first transforming plate and a second transforming plate. The core stress unit is located between the first transforming plate and the second transforming plate. The inner end of the first transforming plate, the ends of the core stress unit and the inner end of the second transforming plate are connected through transforming bolt groups. The nut ends and the bolt sections of the first transforming bolt group are provided with bolt compression material parts respectively. The constraint unit comprises a sleeve and cover plates. The invention further provides a manufacturing process of the bolt transformed anti-buckling energy dissipation bracing. The novel bolt transformed anti-buckling energy dissipation bracing is good in ductility, capable of protecting a core stress component of the bracing against residual stress and residual deformation and good in durability and anti-seismic performance.

Description

technical field [0001] The invention relates to the technical field of structural vibration reduction in construction engineering and bridge engineering, in particular to an anti-buckling energy-dissipating support and a manufacturing process. Background technique [0002] China is a country severely affected by earthquakes with high frequency, high intensity, shallow focus and wide distribution. Earthquakes in China are mainly distributed in five regions: Taiwan, Southwest China, Northwest China, North China, southeast coastal areas and 23 seismic belts. Since 1949, more than 100 destructive earthquakes have hit 22 provinces (autonomous regions and municipalities) in my country. In the 20th century, there were 3 strong earthquakes with a magnitude of 7.6 or more in the world, two of which occurred in China; two strong earthquakes that killed 200,000 people also occurred in China, one was the Haiyuan earthquake in Ningxia in 1920; One was the Tangshan earthquake in Hebei i...
