The response of a structure subjected to moving load can be obtained using coupled or uncoupled methods. method is often preferred since modal superposition applicable, which implies computational efficiency and ease implementation. However, the ignores changes in dynamic features combined structural system due time-varying location load. This paper analyses extent accuracy affected by these ch...

Abstract A method for analysing the vehicle–bridge interaction system with enhanced objectivity is proposed in paper, which considers time-variant and random characteristics allows finding power spectral densities (PSDs) of responses directly from PSD track irregularity. The pseudo-excitation adopted framework, where vehicle modelled as a rigid body bridge using finite element method. vertical ...

A linear dynamic vehicle-bridge interaction method is proposed in this paper. This VBI system can be easily simulated by a step-by-step solution technique based on precise time-integration following discretization of the bridge and modal analysis finite element model. By selecting target structural mode with high participation analysis, huge computational overhead caused multi-degrees freedom l...

Bridge codes adopt values for dynamic allowance in traffic load models that are necessarily conservative to cover for an entire range of bridges with different mechanical characteristics, boundary conditions, and the large number of uncertainties associated to the vehicle-bridge interaction problem. A further level of conservatism occurs due to the independent manner in which the governing stat...

For river crossing bridges, the vehicle-induced vibration can be transmitted to bridge tower and foundation system. This induced low frequency underwater noise radiation cause great harm aquatic organisms. A suspension was selected study sound contribution spatial distribution of noise. bridge-sediment coupling finite element model developed, vehicle-bridge-sediment interaction analysis conduct...

Ongoing inspection and maintenance of bridges poses a challenging task for infrastructure owners who must manage large bridge stocks with limited budgets. Drive-by monitoring approaches, using sensors in vehicle, provide promising solution to this challenge. This paper investigates the use response at point-of-contact between tyre as means frequency. An expression is derived allow contact-point...

During hurricane events, large stress cycles from the non-stationary wind and dynamic vehicle loads could possibly induce damage initiations and propagations. Utilizing the non-stationary wind field modeling techniques and the recent developed vehicle-bridge-wind dynamic analysis framework, this paper initiates the bridge fatigue damage assessment of bridges under vehicle and non-stationary ext...
