Abstract

Abstract

Overlapped tubular K-joints are widely used in long-span space structures. However, there are still doubts and blind zones in forced features, ultimate bearing capacity and influencing factors of these sorts of joints. Nonlinear FEM is used to study the forced performance of the joints under different lap rates, and also analyzed that the effects of branch-main diameter ratio, diameter-thickness ratio of the main, branch-main wall thickness ratio and hidden weld conditions etc on the ultimate capacity of these joints. Finally, a set of formulae to calculate the bearing capacity of the overlapped tubular Kjoints are obtained by nonlinear regressive technique.
- overlapped tubular K-joints,
- nonlinear finite element,
- ultimate capacity,
- hidden weld,
- overlap relation
