STRESS STRAIN STATES AROUND WELD TOE OF CORNER SECTION AND DEFORMATION CAPACITY OF COLD FORMED SHS COLUMN TO THROUGH DIAPHRAGM ROBOTIC WELDED CONNECTION USING 25 DEGREES NARROW GROOVE

Abstract

In this paper, stress strain states around weld toe and deformation capacity limited by ductile crack initiation of cold formed SHS column to through diaphragm robotic welded connection using 25 degrees narrow groove are evaluated by finite element analysis. Analytical parameter is the shape of excess metal determined by the result of sensitivity analysis of stress concentration factor. As a result, there was a correlation between the stress concentration factor and the deformation capacity of column.
