Abstract

This paper summarizes the research progress of rectangular steel pipe or round steel pipe joints in recent years. This paper makes a comprehensive analysis from round steel pipe, square steel pipe and square steel tube. Through experimental study and finite element model analysis, the effects of the geometric parameters such as the main branch diameter (side length) β, the main section diameter (side length) and the branch wall thickness γ, and the τ on the ultimate bearing capacity and the seismic performance of the node are discussed. The study shows that the reasonable diameter, wall thickness and pipe length of the main and branch pipes can significantly improve the ultimate bearing capacity and seismic capacity of the steel pipe node.
