RISParametric Study and Fatigue Life Evaluation Using Effective Notch Stress Approach for Rib-to-Deck Welded Joints in Orthotropic Steel Decks
Publisher: ASCE
Abstract: Fatigue cracking of orthotropic steel decks is a long-standing problem in bridge structures. The notch stress approach has been applied to the fatigue evaluation of steel structures. Parameters of the notch stress approach ...

Fatigue Assessment for Deck-Rib Welded Joints of Orthotropic Steel Deck Using a Simplified Nodal Force Structural Stress Approach
Publisher: ASCE
Abstract: The fatigue cracking of orthotropic steel deck (OSD) has long been a problem of bridge structures. It is meaningful to assess bridge fatigue life using an appropriate method. In this paper, a simplified nodal force structural ...
Fatigue Life Evaluation for Deck-Rib Welding Details of Orthotropic Steel Deck Integrating Mean Stress Effects
Publisher: American Society of Civil Engineers
Abstract: The early fatigue cracking of orthotropic steel decks has been a long-standing problem for heavy traffic regions of China’s long-span bridges. However, the actual fatigue life is much lower than the fatigue life calculated ...
