| Abstract: |
Recently the infinite life fatigue performance of a steel orthotropic deck employing fillet-welded fitted floor beams was evaluated at the ATLSS Engineering Research Centre of Lehigh University by testing a full-scale prototype of a part bridge deck under simulated AASHTO fatigue loading. The test setup was developed based on multi-level 3D finite element analyses (FEA) to reproduce the boundary conditions and the critical stresses in the part deck specimen consistent with the full bridge deck. The fatigue test was run-out after 8 million cycles without any detectable fatigue cracking demonstrating infinite life under site-specific loading. The study provided the foundation for a standardized cost-effective orthotropic deck design that can provide 100 years’ service life. |
