Abstract

the tubular joint of KT type circular steel pipe has abundantly existed with wide application of truss structure of long-span steel pipe. This paper analyzes the influence on joint stiffness through three major factors: thickness of major pipe t0, diameter of branch pipe di, the included angle between branch pipe and major pipe. It applies shell 181, three-dimensional four joints elastic-perfectly shell unit, and elastic-perfectly plastic material to establish finite element model of the tubular joint of KT type circular steel pipe in ANSYS finite element program. Considering geometric nonlinearity and material nonlinearity, this paper gets the ultimate bearing capacity of the tubular joint of KT type circular steel pipe under additional bending moment effect of different joints, has contrastive analysis on ultimate bearing capacity of tubular joint under these different situation, and explains that the ultimate bearing capacity of tubular joint of KT type circular steel pipe will have anti-index curve decrease with increase of additional bending moment M.
