In conventional bridge health monitoring, a number of sensors are deployed on a bridge directly for detecting its various dynamic properties. This is so called “direct method”. But the drawbacks of the direct method are: laborious deployment of sensors, time-consuming, and not portable. Following the previous Yang’s works (2004) in indirect method by using a passing test vehicle as a message re...

This study establishes a short-time stochastic subspace identification (ST-SSI) framework to estimate bridge frequencies by processing the dynamic response of traversing vehicle. The formulation uses dimensionless description that simplifies vehicle-bridge interaction (VBI) problem and brings forward minimum number parameters required for identification. With aid analysis manages successfully a...

Abstract In this study, the results of a vast experimental campaign on applicability smartphone-based technique for bridge monitoring are presented. Specifically, vehicle–bridge interaction (VBI)-based approach is exploited as cost-effective means to estimate natural frequencies bridges, with final aim possibly developing low-cost and diffused infrastructure system. The analysis performed using...

Abstract In bridge structural health monitoring, typically the dynamic response of system is used to assess condition bridge. However, interaction between a and passing vehicle imposes non-stationarity on response, whereby modal parameters become time-dependent detecting damage, for example, based parameters, becomes challenging. Dynamic vehicle-bridge (VBI) responses have mainly been investiga...

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...

When vehicles interact with a bridge, vehicle–bridge interaction (VBI) system is created. The frequency and modal shape of VBI systems have been widely studied, but the damping has not adequately investigated. In recent years, several incidents abnormal bridge vibration due to changes in occurred aroused widespread concern society. Damping an important evaluation index structural dynamic perfor...

A 3D coupled model to simulate vehicle–bridge interactions (VBI) estimate its structural responses and impact factors (IMs) was developed in this study. By health monitoring (SHM) of a real concrete bridge, several data were collected calibrate the bridge by finite element method (FEM). These models provide response terms vertical displacements accelerations. VBI reliable outputs without signif...

Abstract. Recently, there has been an increasing emphasis in the Indirect bridge health monitoring method employing passing vehicles, which is regarded as one of most effective approaches damage screening. However, few researches have conducted on Drive-by inspection using vehicle displacement profile indicator due to challenges measurement and result accuracy. This paper proposes optimization ...

high speed trains are an indispensable part of rapid transportation systems in many countries. as the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...
