Abstract: Field inspections on long-span steel suspension bridges in China reveal that the pavements undergo a fast deterioration process attributed to the flexibility of suspension bridges and the heavy traffic loads. Such extensive ...

Abstract: This study investigates the aging mechanisms and effects of outdoor natural exposure aging (NEA) on bitumen in the Tibetan Autonomous Region of China. Unmodified bitumen (No. 90) and styrene–butadiene–styrene ...

Abstract: The dynamic strain response due to the passing trains is one of the most important indexes in the design and maintenance of long-span steel-truss arch railway bridges. The strain influence line (IL) and dynamic load factor ...

Abstract: Due to the designing characteristics of long span and low stiffness, the high-order vortex-induced vibration (VIV) of suspension bridges may occur under a special wind environment. The prototype monitoring data make it ...

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 ...

Abstract: Ultraviolet (UV) radiation is an important factor that causes the aging of asphalt binders, leading to significant changes in their high- and low-temperature performances and making asphalt pavements more susceptible to ...

Abstract: Considering the new challenges for high-speed railway bridges, the early warning of abnormal train-induced vibrations is necessary for ensuring the operation safety of both the bridge structures and the trains on the bridge. ...

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 ...
