Description

Column-beam connection structure {Colunm-beam connection structure}

The present invention relates to a column-beam connection structure, and more particularly, to a column-beam connection structure for connecting a beam to a column.

Many columns and beams are required in the construction of buildings. Columns and beams are usually made of metal. For example, the pillar may be in the form of a rectangular metal pipe with an empty interior, and the beam may be an H-shaped steel pipe.

After these columns and beams are connected to each other to form the framework of the building, the building can be constructed.

In this way, many columns and beams are used in the construction of a building, and since they must be connected, various techniques for a connecting structure for joining them are known.

In this regard, local buckling occurs at the joint between the column and the beam, and the brittle fracture of the joint occurs after the frame absorbs energy to some extent. In particular, when looking at the previous earthquake damage cases, it was confirmed that brittle fracture occurred at the junction after fracture at the junction and local buckling at the beam.

In particular, in the case of moment-resisting frames of steel structures, column flange-beam flanges are welded or performed in factories to process moment joining, so a joining method other than welding needs to be considered.

On the other hand, in the case of an H-shaped steel column composed of a web and a flange, the joining process is simple in the form of an open cross-section, and in the case of a closed-section steel pipe column, due to the morphological feature of the closed cross-section of the steel pipe, the connection is difficult.
