RISStrain Energy-Based Fatigue Life Evaluation of Deck-to-Rib Welded Joints in OSD Considering Combined Effects of Stochastic Traffic Load and Welded Residual Stress
Publisher: American Society of Civil Engineers
Abstract: Welded residual stress and stochastic traffic at the deck-to-rib welded joints in the orthotropic steel deck (OSD) of bridges highly affects the fatigue life of bridges. This study presents a strain energy-based method to ...
Fatigue Damage Evaluation of Orthotropic Steel Deck Considering Weld Residual Stress Relaxation Based on Continuum Damage Mechanics
Publisher: American Society of Civil Engineers
Abstract: Weld residual stresses (WRSs) in orthotropic steel decks (OSDs) contribute prominently to fatigue damage. WRSs relax during the accumulation of fatigue damage. However, their effects are ignored in conventional methods of ...
Influence of Asphalt Pavement Conditions on Fatigue Damage of Orthotropic Steel Decks: Parametric Analysis
Publisher: American Society of Civil Engineers
Abstract: The function of asphalt pavement on orthotropic steel decks (OSDs) is to transmit and disperse the concentrated wheel loading to the bridge structure and to strengthen the local stiffness of the OSD. Fatigue damage in ...
VARNet: A Transformer-Based Model for Vehicle Trajectory Prediction with Variable-Length Input Sequences
Publisher: American Society of Civil Engineers
Abstract: AbstractPredicting the trajectories of surrounding vehicles is crucial for autonomous driving
systems. In recent years, mainstream methods have used fixed-length input sequences,
relying on historical trajectories of a ...
