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.
