Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] figure 1 It is a structural schematic diagram of a buckling-controlled brace with a bidirectional pyramidal energy-dissipating element at the end, which is composed of an end-restraining section 1, an energy-dissipating section 2, and a straight support section 3. The end-restraining section 1 is fixed at the beam-column node and the Between the sections 2, the energy dissipation section 2 is fixed at both ends of the supporting straight section 3.

[0022] Such as figure 2 As shown, the end restraint section 1 is composed of a square steel plate 4, a T-shaped short steel beam 5, and a connecting plate 6 reserved for components such as beams and columns. The square steel plate 4 is welded to the end of the energy dissipation section 2. Two T-shaped short steel The beam 5 is welded to the square steel plate 4, and the square steel plate 4 and the T-shaped shor...

Abstract

The invention discloses a buckling control support with bidirectional pyramid-shaped energy dissipation units at the ends. The buckling control support with the bidirectional pyramid-shaped energy dissipation units at the ends is characterized in that the buckling control support is composed of end restraint sections, energy dissipation sections and a straight supporting section, and the two ends are connected with beam or column components or joints into a whole through bolts, so that the purpose of increasing the resistant-lateral rigidity of a component is achieved. By the adoption of the buckling control support with the bidirectional pyramid-shaped energy dissipation units at the ends, under the small shock action, the buckling control support is kept elastic; and under the medium or great shock action, the buckling control support is switched to a buckling stage, and a damper effect can be achieved through the good hysteretic energy dissipation performance of the buckling control support. Compared with a traditional buckling restraint support, the steps of additional arrangement of a sleeve outside a core energy dissipation component, grouting and the like in a traditional manufacturing process are omitted on the aspect of the manufacturing technique, and manufacturing is convenient; and the support can be prefabricated in a factory, the quality of the component is guaranteed, the filed construction workload is reduced, energy is saved, and environmental friendliness is achieved.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a buckling control support with two-way pyramid energy-dissipating units at the end, which is suitable for steel structures or concrete structures with buckling restraint supports. Background technique [0002] During the use of steel structures or reinforced concrete structures, ordinary supports will buckle under compression. When the supports buckle under compression, the stiffness and bearing capacity will decrease sharply. Under the action of earthquake or wind, the internal force of the support changes back and forth under the two states of compression and tension. When the support gradually changes from the buckling state to the tension state, the internal force and stiffness of the support are close to zero. Therefore, the hysteretic performance of ordinary supports is poor under repeated loads. In order to solve the problem of buckling under com...
