Description

A connection structure using channel steel to strengthen steel pipe joints

technical field

The utility model relates to the fields of building steel structures and building engineering, in particular to a connection structure using channel steel to strengthen steel pipe nodes.

Background technique

The components composed of steel pipes have excellent tensile, compressive, flexural and torsional properties, and the structure is lighter in weight and can save steel. , box structure. For hollow, thin-walled steel pipes, the radial stiffness is much smaller than the axial stiffness, and the radial bearing capacity at the nodes is much smaller than the axial bearing capacity. The failure mode of the components is mostly manifested as the buckling of the nodes or the cracking of the welds at the connection between the main pipe and the branch pipe, resulting in the failure of the overall structure. Therefore, in order to ensure the basic principle of "strong joints and weak members" in steel structures, a new type of steel pipe connection structure with convenient construction, reasonable structure and improved joint ductility should be developed.

For this reason, those skilled in the art propose a connection structure using channel steel to strengthen steel pipe joints, so as to solve the problems raised in the above background.
