Abstract

The invention discloses a detachable connecting rod connection and energy consumption friction type beam-column joint, and relates to the technical field of steel-concrete combined structures. The detachable connecting rod connection and energy consumption friction type beam-column joint comprises a stand column and a cross beam; the end part of the cross beam is connected with one side of the stand column; the stand column and the cross beam are connected through a connecting assembly; and one end of the connecting assembly is connected with the stand column, and the other end of the connecting assembly is slidably connected with the cross beam. When an earthquake occurs, a hollow steel pipe connecting rod can effectively transmit shearing force and bending moment of the beam-column joint, disassembling and replacing are easy, a steel beam and a connecting piece are in lossless connection, a bolt end plate at the connecting position can slide, and therefore ductility and energy dissipation capacity of the joint are improved. In addition, the wall thickness and the diameter of the hollow steel pipe can be changed according to stress requirements, damage control design is achieved, and the damaged hollow steel pipe is easy to replace. The structure function of the beam-column joint can be rapidly recovered, and therefore the combined-structure detachable connecting rod connection and energy consumption friction type beam-column joint has the advantages of being detachable, capable of achieving damage control design, high in ductility and recoverable in function after the earthquake.

Description

technical field [0001] The invention relates to the technical field of steel-concrete composite structures, in particular to an energy-dissipating friction beam-column joint connected by a detachable connecting rod. Background technique [0002] Since the 1980s, the United States, Japan, and China have done a lot of research work on steel beam-concrete column (RCS) joints, and proposed many different beam-column joint structures. It mainly includes the beam through type and the column through type, both of which can realize the reliable connection between the concrete column and the steel beam, and have a certain energy dissipation capacity. However, the traditional RCS nodes are mainly welded, and it is not easy to dismantle and recycle the structure after the life cycle. There are also problems such as large residual deformation after the earthquake, serious damage to the steel beam, and rapid repair after the earthquake. At present, in the context of carbon neutrality, d...
