Bridge 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 کاملAcoustic Emission Monitoring for Assessment of Steel Bridge Details
Acoustic emission (AE) testing was deployed on details of two large steel Interstate Highway bridges: one cantilever through-truss and one trapezoidal box girder bridge. Quantitative measurements of activity levels at known and suspected crack locations were made by monitoring AE under normal service loads (e.g., live traffic and wind). AE indications were used to direct application of radiogra...
متن کاملLeveraging 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 کاملAnalysis Of Bridge Safety Assessment With Correlation Between Measuring Points For Bridge Health Monitoring
By using linear statistical coefficients such as Pearson, Spearman and Kendall’s, and nonlinear methods such as time-delayed transfer entropy and mutual information, the correlation between the observation stations of bridge health monitoring system is obtained. A model for predicting structural safety based on the correlation coefficients is established, which provides a new research method fo...
متن کاملSensors and Bridge Monitoring System
Rapid developments of structural sensing and control, data acquisition and processing, and computer technologies have made it feasible to monitor the structural health of large-scale structures in real time. SHM of large-scale infrastructures has increasingly attracted extensive interests from both fields of research and application. Based on recent research achievements of developing smart SHM...
