Study on Typhoon Characteristic Based on Bridge Health Monitoring System

Through the wind velocity and direction monitoring system installed on Jiubao Bridge of Qiantang River, Hangzhou city, Zhejiang province, China, a full range of wind velocity and direction data was collected during typhoon HAIKUI in 2012. Based on these data, it was found that, at higher observed elevation, turbulence intensity is lower, and the variation tendency of longitudinal and lateral tu...

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...

Vibration-based Health Monitoring of Highway Bridge Structures Using Output Only Modal Parameter Estimation Technique

This paper discusses the implementation of a Structural Health Monitoring system for a FRP bridge structure using vibration-based monitoring techniques. The need to monitor the long-term performance of fiber reinforced polymer (FRP) composite bridge structures prompted the installation of a vibration-based structural health monitoring system on a recently-built FRP composite highway bridge in C...

Wheelset Condition Monitoring based on pass-by vibration signals

Apart from regular wheel wear such as decreasing wheel diameters and reduced flange thicknesses and heights, wheel flats (WF) and oval wheels (or OOR, Out-Of-Roundness) are the most common wheelset problems for railway vehicles. Within the FP7 Research Project “Saferail”, APT has developed an innovative wheelset monitoring system so-called “Wheel flat and Out of Roundness Monitoring (WORM) syst...
