Parametric analysis and design equation of ultimate capacity for unstiffened overlapped CHS K-joints

CHEN Yu, ZHAO Xianzhong, CHEN Yiyi

Frontiers of Structural and Civil Engineering 2008, Volume 2, Issue 2, Pages 107-115 doi: 10.1007/s11709-008-0014-x

Abstract: A finite element model simulating an experiment on unstiffened, overlapped circular hollow structureUsing this model, the stress distribution, propagation of plasticity and the failure modes of overlappedbrace-to-chord thickness ratio has relatively large effects on the failure mechanism and ultimate capacity of overlappedFinally, based on the design equation of gap joints, a formula predicting the ultimate capacity of overlapped
