Abstract
The objective was to quantify the variation of stress intensity factor to weld root flaw sizes
in steel frame connections. Finite-element analyses were used to study fracture toughness in welded
beam-column connections. Investigations of fracture behavior mainly focused on the standard
pre-Northridge connection geometry. Finite element analysis was performed using the ANSYS
computer program. Stress intensity factor was calculated through a J-integral approach. Results show
that stress intensity factor is not uniform and is largest in the middle of beam flange. Stress intensity
factor increases nearly linear with the increase of flaw size. Backing bars have little effect on weld
fractures.
