Estimation of Fatigue Life of Long-Span Bridge by Considering Vehicle- Bridge Coupled Vibration

To estimate the fatigue life of long-span steel bridge more accurately, this paper proposes a method for estimating the fatigue life of long-span bridges by considering vehicle-bridge coupled vibration. Firstly, the universal equation of vehicle-bridge vibration is derived based on triaxial standard multi-scale model of fatigue vehicle and bridge, and relevant program for vehicle-bridge coupled...

Vibration of Train-Rail-Bridge Interaction Considering Rail Irregularity with Arbitrary Wavelength

A generation method for the rail random irregularity with arbitrary wavelength interval (WI) is developed, and its accuracy and efficiency are demonstrated. Then a moving wheel-rail-bridge interaction element is derived to establish the finite element equations of motion for the train-rail-bridge interaction system, and the flow chart of assembly and calculation for the system equations is give...

An Investigation Into the Vehicle-Curved Bridge Dynamic Interaction

Exploring Indirect Vehicle-Bridge Interaction for Bridge SHM

In this paper, we explore an indirect measurement approach for bridge structural health monitoring (SHM) that collects sensed information from the dynamic responses of many vehicles travelling over a bridge and then makes extensive use of advanced signal processing techniques to determine information about the state of the bridge. We refer to this approach as vehicle-data driven and indirect. W...

Vehicle Induced Vibration on Real Bridge and Integral Abutment Bridge – A Short Review

Nowadays, vehicle-induced vibration is a subject matter interest in the bridge monitoring field. As compared to other types of excitation such as earthquake and accidental impact, the vehicle-induced vibration is often being less considered during the design process of the bridge. The newly implementedcode also does not emphasize on the vibration check for vehicular bridge and requires the engi...
