Abstract

The stress concentration factors of square bird-beak square hollow section (SHS) welded joints under brace axial forces are numerically studied in this paper. Square bird-beak joints considered have T-shapes and are simply supported at their chord ends. Refined finite element models are developed to obtain the strain/stress concentration factors (SNCFs/SCFs) of square bird-beak joints with various dimensions. The FE models are validated by comparing with the experimental data. Critical locations of high stress concentrations are identified. The influences of three major non-dimensional parameters, i.e., brace/chord width ratio β , chord wall slenderness ratio 2γ, and brace/chord wall thickness ratioτ, on the stress concentration factors (SCFs) of square bird-beak T-joints are revealed on the basis of numerous parametric studies.
