Abstract
Highway structures such as bridges are subject to continuous degradation primarily due to ageing and environmental factors. A
rational transport policy requires the monitoring of this transport infrastructure to provide adequate maintenance and guarantee
the required levels of transport service and safety. In Europe, this is now a legal requirement - a European Directive requires all
member states of the European Union to implement a Bridge Management System. However, the process is expensive, requiring
the installation of sensing equipment and data acquisition electronics on the bridge. This paper investigates the use of an
instrumented vehicle fitted with accelerometers on its axles to monitor the dynamic behaviour of bridges as an indicator of its
structural condition. This approach eliminates the need for any on-site installation of measurement equipment. A simplified
half-car vehicle-bridge interaction model is used in theoretical simulations to test the possibility of extracting the dynamic
parameters of the bridge from the spectra of the vehicle accelerations. The effect of vehicle speed, vehicle mass and bridge span
length on the detection of the bridge dynamic parameters are investigated. The algorithm is highly sensitive to the condition of
the road profile and simulations are carried out for both smooth and rough profiles
