This experimental research project quantifies the fracture resistance of fatigue cracked I-girders fabricated from two grades of high performance steel. The HPS-485W and HPS-690W steel grades have substantially higher toughness compared to conve
Results show I-girder flanges fabricated from HPS-485W steel are capable of reaching their elastic limit load before fracture failure. Limit load analysis is shown to be an effective means of assessing failure when steel has upper shelf fracture
Ignoring strain hardening effects, a practical, upper bound performance limit state for I-girder flanges is determined to be yield on the net section. Sudden flange failure is expected when this limit state is exceeded. The I-girder geometry doe
