Effects of Flange Width Ratio on the Residual Stresses in Welded Monosymmetric I-Section

Abstract:

This paper used ANSYS finite element software to simulate the residual stress of the welded monosymmetric I-section and obtain residual stress distribution curves, analyzed the influence of flange width ratio on welding residual stress peak value and the stress distribution. The studies have shown that: with the flange width ratio decrease gradually, peak value of residual stress in flange and web is to increase; peak value of residual tensile stresses in both flange and web close to the steel yield strength f_y, peak value of residual compressive stresses is 0.4f_y in wide flange and the web near wide flange and in narrow flange and web near narrow flange is 0.3f_y; the distribution of the residual tensile stress in the flange and web have growth trend.
