Leveraging Structural Health Monitoring for Bridge Condition Assessment
Highway bridge infrastructure is a key aspect of the US transportation system. Efficient maintenance is important for preserving the integrity and improving the condition of aging national bridge infrastructure. Highway bridge condition is typically assessed using visual inspections and accompanying non-destructive field tests. This paper presents a solution that leverages low-cost Structural H...
متن کاملBridge Structural Condition Assessment Based on Vibration and Traffic Monitoring
A stochastic model of traffic excitation on bridges is developed assuming that the arrival of vehicles traversing a bridge modeled as an elastic beam follows a Poisson process, and that the contact force of a vehicle on the bridge deck can be converted to equivalent dynamic loads at the nodes of the beam elements. The parameters in this model, such as the Poisson arrival rate and the stochastic...
متن کاملResearch Article Bridge Condition Assessment Using DNumbers
Bridge condition assessment is a complex problem influenced by many factors. The uncertain environment increases more its complexity. Due to the uncertainty in the process of assessment, one of the key problems is the representation of assessment results. Though there exists many methods that can deal with uncertain information, however, they have more or less deficiencies. In this paper, a new...

متن کاملIntegrating Bridge Structural Health Monitoring and Condition-Based Maintenance Management
The development of structural health monitoring (SHM) technology has evolved for over fifteen years in Hong Kong since the implementation of the “Wind And Structural Health Monitoring System (WASHMS)” on the suspension Tsing Ma Bridge in 1997. Five cable-supported bridges in Hong Kong, namely the Tsing Ma (suspension) Bridge, the Kap Shui Mun (cable-stayed) Bridge, the Ting Kau (cable-stayed) B...
