[0019] The present invention will be further explained below in conjunction with the drawings.

[0020] figure 1 It is a schematic diagram of the structure of the buckling control support with staggered pyramidal energy dissipation elements at the end. It is composed of an end restraint section 1, an energy dissipation section 2 and a straight support section 3. The end restraint section 1 is fixed at the beam-column node and the energy dissipation Between the sections 2, the energy-consuming section 2 is fixed at both ends of the supporting straight section 3.

[0021] 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 beams and columns. The square steel plate 4 is welded to the end of the energy consuming section 2. Beam 5 is welded to square steel plate 4, square steel plate 4 and T-shaped short steel beam 5 are respectively shown Figure 5 , 6 Shown. The connecting ...

Abstract

The invention discloses a buckling control support with the end provided with a staggered pyramid type energy consumption unit. The buckling control support is characterized by being composed of an end restraint section, energy consumption sections and a supporting flat section. The two ends of the buckling control support are connected with beams, column components or nodes through bolts to form a whole, so as to achieve the objective of improving lateral stiffness resistance of the components. The buckling control support with the end provided with the staggered pyramid type energy consumption unit maintains elasticity under the effect of a small earthquake; when the effect of a medium earthquake or a large earthquake occurs, the buckling control support enters a yielding phase, and the effect of a damper can be achieved due to the good hysteresis energy consumption performance of the buckling control support. Compared with a conventional buckling restraint support, according to the buckling control support, the processes of adding a sleeve outside a core energy consumption component in the conventional manufacturing process and performing grouting and the like are avoided in manufacturing process, and the buckling control support is convenient to manufacture. The support can be prefabricated in a factory, the component quality is guaranteed, the site construction operation workload is reduced, and the buckling control support saves energy and is environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of building structures, in particular to a buckling control support with staggered pyramid-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 compre...
