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: unstiffened, overlapped circular hollow structure (CHS) K-joints was generated and validated by comparing the ultimateThe results of finite element parametric analysis indicate that the brace-to-chord thickness ratio hasrelatively large effects on the failure mechanism and ultimate capacity of overlapped joints.It was also found that the absence of hidden welds has less significance on the ultimate capacity ofCHS K-joints was derived by applying multivariate regression analysis.
