Novel flange-disconnected beam-column connection joint

Abstract

The invention discloses a novel flange-disconnected beam-column connection node and relates to the technical field of connection nodes. The novel flange-disconnected beam-column connection node comprises an upper flange plate, an upper connecting plate, a lower flange plate, a lower connecting plate and a web plate, wherein the upper flange plate comprises a first upper flange plate and a second upper flange plate, and an upper flange notch is formed between the first upper flange plate and the second upper flange plate; two ends of the upper connecting plate are fixed to the first upper flange plate and the second upper flange plate respectively, and the cross section area of the upper connecting plate is smaller than that of the first upper flange plate; the lower flange plate comprises a first lower flange plate and a second lower flange plate, and a lower flange notch is formed between the first lower flange plate and the second lower flange plate; two ends of the lower connecting plate are fixed to the first lower flange plate and the second lower flange plate respectively, and the cross section area of the lower connecting plate is smaller than that of the first lower flange plate; and one end of the upper flange plate and one end of the lower flange plate are fixed on one side of the web plate. The connection node is advantaged in that plastic hinges are generated through the upper connecting plate and the lower connecting plate, and mounting and manufacturing are convenient.

Description

technical field [0001] The invention relates to the technical field of connecting nodes, in particular to a novel flange disconnected beam-column connecting node. Background technique [0002] In recent years, the number of steel structure buildings in my country has gradually increased. The steel structure is different from the concrete structure. In addition to the design of its own components, the joint is also a very important design item. For a long time, a large number of joints used in our country are still traditional styles, and these styles have been difficult to meet the needs of various forms of steel structure buildings. Therefore, it is imminent to develop new nodes with good applicability. [0003] At present, when designing steel structure connections, for beam-to-column connections, when the checking calculation is not satisfied, the joints need to be strengthened. Commonly used reinforcement methods are as follows: 1. Reinforcement with cover plate; 2. R...

Problems solved by technology

However, this kind of connection has relatively high requirements for processing accuracy, that is, the weakened part must be smooth, and there must be no defects such as burrs and gaps that will cause stress concentration.
