Rapid and accurate identification of moving load is crucial for bridge operation management early warning overload events. However, it hard to obtain them rapidly via traditional machine learning methods, due their massive model parameters complex network structure. To this end, paper proposes a novel method perform loads using MobileNetV2 transfer learning. Specifically, the dynamic responses ...

block stops. There are few streets over which street cars are operated that are wide enough for the street-car lane, a lane for moving vehicles, and a space for parking. The usual condition is that the moving vehicles must use the car-track space, since the other lane is used for parked vehicles. Just one parked vehicle per city block will keep the outside lane from being used by moving vehicle...

the vibrations produced by trains include two parts which are deterministic and random vibrations. due to variation of dynamic loads and patterns of load-time, the random vibration of moving train is one of the most important issues in the field of railway engineering. one of the important sources in producing the train vibrations is rail roughness and irregularities. in this paper, responses o...

A three-dimensional finite element model was developed to investigate dynamic response of track-embankment-ground system subjected to moving loads caused by high speed trains. The track-embankment-ground systems such as the sleepers, the ballast, the embankment, and the ground are represented by 8-noded solid elements. The infinite elements are used to represent the infinite boundary condition ...

Recent structural collapses of bridges and damaging occurred on deck and dampers of suspension bridges, are driving the development of monitoring techniques for the structural integrity assessment of primary lifelines. Structural Health Monitoring combines a variety of methods for observed dynamic systems response detection of different structural systems. Among others techniques, Operational M...
