| Summary: | This thesis presents a fatigue reliability analysis of welded joint by using fracture mechanics
approach. Numerically analysis was focused on a transverse-stiffener to bottom flange
welded joint of a typical steel bridge. Crack growth model is based on the principles of
fracture mechanics theory, while reliability analysis is performed by using Monte Carlo
Simulation. Crack propagation rate analysis shows that crack growth model has a good
accuration compared to the experiment results that has been done. Fatigue reliability
analysis also compared to FORM (First Order Reliability Method) analysis that has been
done by Mladen Lukic (Probabilistic Assesment of Welded Joint Versus Fatigue dan
Fracture). Comparation shows that there is a diferrence in service time to get the same ?
value (reliability index). |
