Investigation of fatigue resistance of fillet-welded tube connection details for sign support structures

Hyungjoo CHOI, Husam NAJM

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 1, Pages 199-214 doi: 10.1007/s11709-019-0592-9

Abstract: Stiffened and unstiffened fillet-welded tube-to-transverse plate connection details are widely used forThe main objective of this study is to evaluate fatigue resistance of fillet-welded tube connection detailsof fatigue life, fatigue damage, and fatigue safety factor to determine the fatigue performance of fillet-weldedThe results of this investigation provides fatigue resistance of fillet-welded connection details in

Parametric equations for notch stress concentration factors of rib–deck welds under bending loading

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 3, Pages 595-608 doi: 10.1007/s11709-021-0720-1

Abstract: The effective notch stress approach for evaluating the fatigue strength of rib–deck welds requires notchFirst, we developed a model for investigating the effective notch stress in rib–deck welds.fatigue design curve of FAT225 seems to be conservative for evaluating the fatigue strength of rib–deck welds
