A method combining fracture mechanics and finite element analysis was presented to quantify the variation of stress intensity factor to weld root flaw sizes in steel frame connections.Finite element analysis was performed using the ANSYS computer program.Fracture toughness demands were evaluated in terms of mode I stress intensity factor.Stress intensity factor was calculated through a J-integral approach.The connection geometry was separately investigated in terms of the beam and column properties.The influences of beam length,column length and weld leg size on the stress intensity factor were analyzed.The fracture toughness demands for the flaw on the top of the beam flange and for the bottom surface were respectively studied.Results showed that the panel zone deformation has great effect on the stress intensity factor.The likelihood of top flange fractures is smaller than that of bottom flange fracture.Stress intensity factor increases with the increase of beam parameters,and decreases with the increase of column parameters.Finally,formulas for stress intensity factors are deduced.
