Embodiment 1

[0027] Such as Figure 1-2 As shown, the present invention provides a self-resetting beam-column frictional energy-dissipating node. The self-resetting beam-column frictional energy-dissipating node includes an upper flange plate 3, a lower flange plate 11, a web 6 and a self-resetting corner brace 10. The flange plate 3, the lower flange plate 11 and one end of the web plate 6 are all welded to the side of the steel frame column 1 to form a connecting short beam with a cavity in the middle, and the connecting short beam is used to connect the steel frame column 1 and the steel frame beam 2 . The steel frame column 1 and the steel frame beam 2 both have an I-shaped cross-section, and reinforcing ribs are evenly distributed on them. The web 6 is two pieces. The end of the steel frame beam 2 is inserted into the cavity of the connecting short beam, and the connecting short beam and the steel frame beam 2 are connected by high-strength bolts 4 . Both the lower flange plate 11 ...

Embodiment 2

[0031] Such as Figure 3-4 As shown, a friction backing plate 8 is provided between the contact surface of the upper flange plate 3 and the steel frame beam 2, and a friction backing plate 8 is also provided between the contact surface of the upper flange plate 3 and the head of the high-strength bolt 4; A steel plate 7 is arranged between the plane where the friction pad 8 contacts the head of the high-strength bolt 4 . The connection position between the lower flange plate 11 and the steel frame beam 2 is not provided with a friction pad 8 . Other parts are the same as embodiment one.

[0032] The self-resetting corner brace 10 provided in the self-resetting beam-column frictional energy-dissipating node of the present invention can provide self-restoring force, has strong energy consumption and self-resetting ability, and has a simple structure and strong stability, so that the joint can be quickly restored after the earthquake initial state.

Abstract

The invention discloses a self-reset beam column friction energy consumption node which comprises an upper flange plate, a lower flange plate, a web and a self-reset angle brace. One end of the upper flange plate, one end of the lower flange plate and one end of the web are all fixedly connected to the side face of a steel frame column to form a connecting short beam. One end of the connecting short beam is connected to the steel frame column, and the other end is connected with a steel frame beam. The joint of the connecting short beam and the steel frame beam can generate left-right displacement when bearing external force. The self-reset angle brace is connected with the steel frame column and the steel frame beam through ear plates at the two ends respectively. Through the sliding friction of a friction base plate at the upper flange plate or the lower flange plate or the web and the self-reset angle brace at the lower flange position of the steel frame beam, earthquake energy is consumed, and the node can automatically restore the initial state after an earthquake. The self-reset beam column friction energy consumption node is simple in structure and convenient to construct and can be widely applied to various steel structure buildings.

Description

technical field [0001] The invention relates to the technical field of anti-seismic devices, in particular to a self-resetting beam-column frictional energy-dissipating node. Background technique [0002] my country is a country prone to earthquakes, and has high requirements for the seismic performance of building structures. Especially, there are many high-rise and super high-rise buildings at present, and the seismic problems are more prominent. In recent years, recoverable functional structures have become a research hotspot and have attracted much attention. [0003] Steel structures have the advantages of high strength, good seismic performance, and short construction period, and are widely used in various building structures. However, the traditional steel frame structure has weak seismic performance and poor self-resetting ability. It is prone to deformation and damage in strong earthquakes, and the damaged structure cannot be automatically repaired after the damage...
