Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] figure 1 It is a structural schematic diagram of buckling-controlled brace with diamond-shaped energy-dissipating elements at the end, which is composed of end-restraining section 1, energy-dissipating section 2 and support straight section 3, and end-restraining section 1 is fixed at the beam-column node and energy-dissipating section 2, the energy dissipation section 2 is fixed at both ends of the supporting straight section 3.

[0024] 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 short steel beam 5 are ...

Abstract

The invention discloses a buckling control support with diamond type energy dissipation units at the ends. The buckling control support is characterized by being composed of end restraint sections, energy dissipation sections and a straight supporting section, wherein the two ends of the buckling control support are connected with beam and column members or joints into a whole through high-strength bolts to achieve the purpose of improving the lateral stiffness of the members. The buckling control support with the diamond type energy dissipation units at the ends maintains resilience under the action of a small earthquake and enters a yield stage under the action of a medium earthquake or a major earthquake, and the effect of a damper can be achieved due to the good hystersis energy dissipation performance of the buckling control support. Compared with a traditional buckling control support, the procedures of adding a sleeve outside a core energy dissipation member, performing grouting and the like in the traditional manufacturing process are omitted in the manufacturing technology, and manufacturing is convenient; the support can be prefabricated in a factory, the member quality is guaranteed, the workload of site construction operation is reduced, and energy conservation and environment protection are achieved.

Description

technical field [0001] The invention belongs to the technical field of building structures, in particular to a buckling control support with diamond-shaped energy dissipation 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 compression and ...
