英文摘要
A new structural integrity evaluation method for steel structures with fatigue cracks was constructed based on remote quantitative nondestructive crack evaluation technique utilizing self-reference lock-in infrared thermography and digital image correlation, as well as fracture mechanics analysis based on on-site thermoelastic stress measurement. It was found from experimental studies for laboratory samples and actual steel bridges that proposed method enabled us to conduct completely remote, noncontact and nondestructive detection of fatigue cracks and to evaluate stress distribution around fatigue cracks.
