Abstract

The invention discloses a bush constraint buckling-preventing support with a diamond-shaped energy dissipation unit. The bush constraint buckling-preventing support is characterized in that the bush constraint buckling-preventing support comprises an end constraint segment, an energy dissipation segment and a bush; and the two ends are connected with beams or column components or nodes to form a whole through bolts so as to achieve the purpose of improving of the resistant-lateral rigidity of components. The bush constraint buckling-preventing support with the diamond-shaped energy dissipation unit is adopted, and thus under the action of a small earthquake, the bush constraint buckling-preventing support keeps elasticity; and under the action of a medium earthquake or a severe earthquake, the energy dissipation segment enters a yield stage, and the effect of a damper can further be achieved through the good hysteretic energy dissipation performance of the energy dissipation segment. The bush constraint buckling-preventing support with the diamond-shaped energy dissipation unit can be prefabricated and formed in a factory, the quality of the components is ensured, the workload of site 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, and in particular relates to a casing-constrained anti-buckling support with diamond-shaped energy-dissipating units, which is suitable for steel structures or concrete structures with buckling-constrained 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 und...
