Problems solved by technology

[0002] The design and construction of anti-seismic buildings have attracted more and more attention. According to modern anti-seismic design theory, even if there is no catastrophic collapse of buildings under the action of earthquakes, the cost of repairing or demolishing them is relatively low. It is very huge. In order to reduce the loss after the earthquake, how to reduce the residual deformation of steel structures has become a research hotspot in today's society. The retrieved application number is 201922454578.5, which discloses a self-centering steel frame column that uses sliding friction to dissipate energy. The foot node includes a steel column, a reinforced steel plate and a foundation beam, the steel column includes a left flange plate, a right flange plate and a column web, and the left side and the right side of the column web respectively fix the left flange plate and the right w

Abstract

The invention belongs to the field of steel frame column bases, particularly relates to a self-centering steel frame column base joint structure utilizing sliding friction to consume energy, and aims at solving the problems that an existing steel frame column base joint structure is single in dynamic nature, low in energy consumption of sliding friction, low in utilization rate of the sliding friction and poor in flexibility of an overall structure. According to the technical scheme, the column base comprises a column base bottom plate, two column base auxiliary plates, two column base main plates, two node installation assemblies, two side edge sliding assemblies and two bottom sliding assemblies, the two column base auxiliary plates are both installed on the top of the column base bottom plate in a sliding mode, the column base main plates are arranged on the corresponding column base auxiliary plates, and the two node installation assemblies are arranged on the two side edge sliding assemblies. And the node mounting assemblies are arranged on the corresponding column foot auxiliary plates. The steel frame column base joint structure is flexible in dynamic nature, high in energy consumption of sliding friction, high in utilization rate of the sliding friction and good in flexibility of the whole structure.
