Background
In a high-rise steel structure building, vertical loads, wind loads, earthquake action and the like are finally borne by a structure body and are gradually transmitted to a foundation. As a steel column of a key vertical force transmission component, internal force generated by external actions of structures such as axial force, bending moment, shearing force and the like needs to be reliably transmitted to a foundation, and the safety of components and nodes in the transmission process is ensured.
Along with the position difference of the structure, the internal force born by the component is changed constantly, the cross section of the component is smaller as the component goes upwards, and the stress of the steel column at the upper part is smaller than that of the steel column at the lower part. In engineering design, on the basis of meeting the structural safety, the economic problem of the structure is mainly considered, which is shown in that the steel column is continuously changed in section size, and the size of the section size and the thickness of the steel plate are gradually reduced upwards.

The common section form of the existing steel column is a box-type steel column or a steel pipe column, the common node method mainly comprises a table-conical node, and the gradient of the node is required and is generally in the range of 1: 4-1: 6.
A frustum-conical variable cross-section node of a box-type steel column is characterized in that four trapezoidal steel plates are adopted in a node area to form two different cross-sectional sizes of an upper opening and a lower opening, and 12 full-penetration primary welding seams are arranged among the four trapezoidal plates and between the upper opening and the lower opening and the upper column and the lower column, so that high requirements are provided for manufacturing of component nodes.
