Abstract

The invention relates to the technical field of building structures, in particular to a column base capable of dissipating energy through swinging. The column base comprises a base, a prefabricated column and a friction energy dissipation damper. A groove is formed in the base. The end of the prefabricated column is located in the groove. The friction energy dissipation damper is energy dissipation assemblies arranged oppositely. Each energy dissipation assembly comprises first connecting plates and second connecting plates, the first connecting plates are perpendicularly connected with the side wall of the end of the prefabricated column, the second connecting plates are perpendicularly connected with the side wall of the groove, and metal energy dissipation friction plates are arranged between the second connecting plates and the first connecting plates. By the adoption of the column base, the tension transferred to a foundation becomes a controllable factor and is released to a great extent, the defect that a concrete structure is poor in anti-pull-out property is overcome, the column base can be lifted to swing and participate in energy dissipation, important vertical bearing and anti-side-force components in the structure are effectively protected, the basic cycle can also be prolonged after the structure is allowed to swing, the seismic response of the structure is relieved to a certain extent, and a multiple energy dissipation and anti-earthquake mechanism of the structure is formed.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a swinging energy-dissipating column base. Background technique [0002] At present, the buckling-resistant braced frame system is a relatively commonly used structural system in the current building structure system. Whether it is for new buildings or existing building reinforcement, its application range is becoming wider and wider. [0003] The application of buckling-resistant braces to high-rise concrete frame structures has become a new trend, which can not only reduce the overall self-weight of traditional frame shear wall structures, but also reduce the earthquake effect, and at the same time, the buckling-resistant braced frame structure system overcomes the compression of traditional steel support members. The disadvantage of easy buckling, its energy dissipation effect is stable and reliable. However, the application of anti-buckling braces to high-rise co...
