Double-yield-point linear all-steel buckling-resistant energy-consuming support

Abstract

The invention discloses a double-yield-point linear all-steel buckling-resistant energy-consuming support comprising a core energy-consuming plate, wherein the core energy-consuming plate comprises low-yield-point steel plates (1) and an aluminum alloy plate (2); one aluminum alloy plate (2) is clamped between two low-yield-point steel plates (1) with uniform shapes and specifications, so that the plates are overlapped to form the line-shape core energy-consuming plate; the core energy-consuming plate is embedded in the abdominal cavity of a double-web I-shaped steel constrained component (3) consisting of two pieces of I-shaped steel so as to form the double-yield-point linear all-steel buckling-resistant energy-consuming support; the two ends of the core energy-consuming plate are positioned outside the abdominal cavity of the double-web I-shaped steel constrained component (3) and are used for connecting with an engineering structure. According to the double-yield-point linear all-steel buckling-resistant energy-consuming support provided by the invention, a plurality of energy-consuming plates made of different materials serve as the core, so that the design requirements of staged yield energy consumption under small shake, medium shake and great shake as well as multi-performance standards and targets can be met. The bearing capacity is high and the end parts of the core energy-consuming plate are strengthened without welding, so that a fatigue failure caused by end part welding is avoided.

technical field [0001] The present invention relates to the field of anti-seismic technology, in particular to an energy-dissipating plate of different materials as the core, which can meet the design requirements of yield energy consumption in stages under small earthquakes, moderate earthquakes and large earthquakes, and achieve multiple performance levels and goals. Double yield point in-line all-steel anti-buckling energy-dissipating support. Background technique [0002] The existing in-line all-steel anti-buckling energy-dissipating brace currently has the following problems: [0003] 1. At present, most of the core energy-dissipating plates used in engineering for anti-buckling energy-dissipating supports are single-core equal-section steel plates, and a few are variable-section steel plates. Single-core steel plates cannot meet the demand for large bearing capacity, and the deformation of variable-section core energy-dissipating steel plates is mostly concentrated I...

[0003] 1. At present, most of the core energy-dissipating plates used in engineering for anti-buckling energy-dissipating supports are single-core equal-section steel plates, and a few are variable-section steel plates. Single-core steel plates cannot meet the demand for large bearing capacity, and the deformation of variable-section core energy-dissipating steel plates is mostly concentrated In small cross-sections, the energy dissipation in the staged yield section under small earthquakes, moderate earthquakes and large earthquakes cannot be realized;

[0004] 2. A small number of buckling-resistant energy-dissipating supports that have been developed in stages are mostly reinforced by welding at the end, and the failure mode is that the weld at the end of the core energy-dissipating plate breaks, and the fatigue performance is not good;
