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, large-span structures or structures with high storey heights or structures with cross-story columns have emerged in large numbers. In the case of energy-dissipating braces, the calculated length of buckling-resistant energy-dissipating braces is relatively long. In order to meet structural requirements, the section of buckling-resistant energy-dissipating braces often does not meet architectural requirements, and the amount of materials used is large, and the utilization rate of materials is not high.

Abstract

The invention discloses a sleeve-type flexing constraint support, and the support comprises a main core stress component and a constraint component. The central parts of the front and rear sides of the main core stress component are respectively provided with a reinforcing structure segment, and the reinforcing structure segments are called as a front no-yield conversion segment and a rear no-yield conversion segment. The front no-yield conversion segment comprises a first auxiliary core stress component, and the rear no-yield conversion segment comprises a second auxiliary core stress component. The first and second auxiliary core stress components are symmetrically welded at the central parts of the front and rear sides of the main core stress component. The main core stress component, the first auxiliary core stress component and the second auxiliary core stress component form a crossing structure. The constraint component comprises a yield segment constraint device for constraining the main core stress component, a left constraining device for constraining the front no-yield conversion segment, and a right constraining device for constraining the rear no-yield conversion segment. The support can save materials, achieves the optimal economic performance, and can meet the requirements of buildings better.

Description

technical field [0001] The invention relates to the technical field of vibration reduction of construction engineering structures, in particular to a sleeve-type buckling restraint support. Background technique [0002] In recent decades, anti-buckling energy-dissipating braces have been widely used in countries and regions such as the United States, Japan, and Taiwan. The anti-buckling energy-dissipating brace is a kind of brace that does not buckle under tension and compression, and has more stable mechanical properties than traditional braces. The buckling restraint brace 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-dissipating brace consists of five parts: constrained yielding segment; constrained no...
