FATIGUE PROPERTIES AND RETROFITTING OF EXISTING ORTHOTROPIC STEEL BRIDGE DECKS

Fatigue Reliability Assessment of Orthotropic Steel Bridge Decks Based on Probabilistic Multi-scale Finite Element Analysis

The orthotropic steel deck (OSD) has been utilized successfully for thousands of bridges worldwide; however, fatigue cracking of the OSD has been observed frequently due to the complicated welded details combined with stresses that can be difficult to quantify, and the uncertainties in fatigue damage accumulation. In this paper, a fatigue reliability assessment method is proposed based on a com...

Fatigue Reliability Assessment for Orthotropic Steel Decks Based on Long-Term Strain Monitoring

A time-dependent fatigue reliability assessment approach is proposed for welded details of orthotropic steel decks (OSDs) using long-term strain monitoring data. The fatigue reliability limit function of the welded details is established based on the Eurocode specifications. Depending on the distribution characteristics of the measured daily equivalent stress range, either the lognormal distrib...

State-of-art of Asphalt surfacings on long-spanned orthotropic steel deck in China

Reliable and durable asphalt surfacing systems still remain to be desired for the long-spanned orthotropic steel bridges as the nationally and internationally reports on distresses in deck pavement. Based on ten-year research works, this paper has presented a brief review and discussion of the Chinese practices and experiences of deck pavement on long-spanned steel bridges, including issues of ...
