Parametric studies have been carried out on Tubular K joint using the finite element method to estimate the Stress Concentration Factor along the intersection of the branch and chord tubes. Three load cases, viz., axial symmetric, axial asymmetric and inplane bending are considered for the analysis. Multiple correlation and regression analyses have been used to develop formulae for the maximum SCF and for the variation of SCF along the intersection. Comparison of the results from author's formulae for maximum SCF and Kuang formulae has been made. Analysis of regression for the newly developed formulae is shown to demonstrate the confidence of the equations.
