Stress concentration factors of diamond bird-beak SHS T-joints under brace loading

Finite element analysis and formulae for stress concentration factors of diamond bird-beak SHS T-joints

“…2) were tested under brace loading, as reported in Ref. [20]. As this experimental study forms the basis of the numerical study in this paper and the test results are used to calibrate the FE models, a brief summary is given in this section.…”

“…no larger than t 0 /3, as used in the present paper) and an extrapolation method is used to determine the hot spot strain (or stress). Table 1 Dimensions and non-dimensional parameters of specimens for diamond bird-beak SHS T-joints [20].…”

“…The conclusion in [19] was purely based on FE analysis without any experimental verification. More recently experimental study on SCFs of diamond bird-beak SHS T-joints was carried out by Tong et al [20]. Hot spot stress concept for the fatigue strength assessment of welded tubular joints has been widely accepted as presented in CIDECT Design Guide No.…”

“…In this paper, three-dimensional FE model was validated by experimental data in [20] before it is utilized for parametric study.…”

Stress concentration factors and fatigue behavior of square bird-beak SHS T-joints under out-of-plane bending

“…Keizer et al [13] investigated the stress concentration factors of diamond bird-beak joints under brace axial forces in his master's degree thesis. Tong et al [14,15] presented an experimental study of stress concentration factors for diamond bird-beak T-joints under axial force and in-plane bending on the brace. Cheng et al [16] carried out tests to obtain stress concentration factors of square bird-beak T-joints under chord and brace axial forces.…”
