Abstract

Evaluation of fatigue damage propagation is necessary to ensure safety and to estimate the remaining life of the aging steel bridges. In this study, thermoelastic stress analysis (TSA) was applied for on-site measurement of stress distributions around fatigue cracks, and the future crack propagation behavior was estimated by the fracture mechanics approach. Experimental studies were conducted for laboratory specimens which modeled a part of welded structure in steel bridges. The stress intensity factors were calculated from stress distributions measured by TSA technique. Further TSA technique was applied to evaluate the effectiveness of repair works for defective portions. Severity reduction in stress distribution around the fatigue crack after treatment was confirmed for actual steel bridge members by TSA.
