Vibration analysis of bridges induced by train loads is a crucial aspect railway design, particularly considering the complexity vehicle components such as bogie-suspension systems. Consequently, engineers have endeavored to improve computational efficiency and applicability models using finite-element method. This paper introduces toolbox implemented in ABAQUS through user-defined element (UEL...

This paper reports on the analysis of the signals sent by accelerometers fixed on the axles of a vehicle which passes over a bridge. The length of the bridge is divided into some parts and the transmissibility measurement is applied to the signals recorded by two following instrumented axles. As the transmissibility procedure is performed on the divided signals, the method is called Short Time ...

OBJECTIVE The aim of this paper is to bridge the gap between the corpus of imitation research and video-based intervention (VBI) research, and consider the impact imitation skills may be having on VBI outcomes and highlight potential areas for improving efficacy. METHOD A review of the imitation literature was conducted focusing on imitation skill deficits in children with autism followed by ...

Objective: The aim of this paper is to bridge the gap between the corpus of imitation research and video based intervention (VBI) research, and consider the impact imitation skills may be having on VBI outcomes and to what extent this can be utilised to improve outcomes. Method: A review of the imitation literature was conducted focusing on imitation skill deficits in children with autism follo...

Deterioration of bridges under repeated traffic loading has called attention to the need for improvements in the understanding of vehicle–bridge interaction. While analytical and numerical models have been previously explored to describe the interaction that exists between a sprung mass (i.e., a moving vehicle) and an elastic beam (i.e., bridge), comparatively less research has been focused on ...

A novel baseline-free method for damage detection of vehicle-bridge interaction (VBI) systems is proposed. The proposed physics-based, in contrast to many prevailing approaches, which are purely data-based techniques. It uses incomplete measurement data by incorporating the static condensation transformation matrix into equations obtain final formulas. However, damaged beam not known a priori. ...

This study presents experimental investigations on dynamic characteristics of bridges coupled with vehicles in order to clarify the vehicle-bridge interaction under earthquakes. Oscillator experiment is carried out at a one-box girder bridge coupled with a vehicle. Both acceleration responses of the bridge and those of the vehicle are measured in horizontal and vertical directions. The dynamic ...
