Problems solved by technology

[0004] At present, there are many structures of buckling-resistant energy-dissipating braces. Experts and scholars in related fields have greatly improved the structure of buckling-resistant energy-dissipating braces, and the economy and process difficulty of buckling-resistant energy-dissipating braces have been greatly reduced.
However, the existing anti-buckling energy-dissipating braces still have the following problems: In recent years, with the rapid development of the national economy, long-span steel structures (especially steel bridges), steel structures with high storey heights, and steel structures with cross-story columns When these structures adopt anti-buckling energy-dissipating braces, the calculation length of anti-buckling energy-dissipating braces is longer. At this time, in order to meet the structural requirements, the sections of anti-buckling energy-dissipating braces often do not meet the architectural requirements of steel structures. (that is, size requirements and aesthetic requirements), the amount of materials used is relatively large, and the utilization rate of materials is not high

Abstract

The invention discloses a combined type buckling prevention energy consumption support which comprises a main core stress component and a constraint component. The middle of the front side of the main core stress component is provided with a front non-buckling conversion segment, and the middle of the rear side of the main core stress component is provided with a rear non-buckling conversion segment. The front non-buckling conversion segment comprises a first pair of core stress components, and the rear non-buckling conversion segment comprises a second pair of core stress components. The first pair of core stress components and the second pair of core stress components are symmetrically fixed to the middle of the front side and the middle of the rear side of the main core stress component. The main core stress component, the first pair of core stress components and the second pair of core stress components form a crossed structure. The constraint component comprises a buckling segment constraint device for constraining the main core stress component, a left constraint device for constraining the front non-buckling conversion segment, and a right constraint device used for constraining the rear non-buckling conversion segment. According to the combined type buckling prevention energy consumption support, rigidity is effectively promoted, the material utilization amount is reduced, the utilization rate is improved, and self weight is reduced.

Description

Technical field [0001] The invention relates to the technical field of steel structure engineering structure vibration reduction, in particular to a combined anti-buckling energy-consuming support. Background technique [0002] In recent decades, anti-buckling energy-consuming supports have been widely used in countries and regions such as the United States, Japan, and Taiwan. The anti-buckling energy dissipation support is a kind of support that does not buckle under tension and compression, and has more stable mechanical properties than traditional supports. The buckling restraint support can not only improve the stiffness and ductility of the structure, but also use the hysteretic properties of the steel to consume the energy of the structure due to the horizontal load, which is of great significance to the improvement of the seismic capacity of the structure. [0003] The general anti-buckling energy dissipation support consists of five parts: constrained yield section; constr...
