and experimental verification. The idea of indirect method is based on the coupling nature of a vehicle moving
on a bridge proposed by Yang et al. (2004), in which the bridge response can be recorded by the passing vehicle.
Thus, one can extract the bridge frequencies from the response of the moving instrumented vehicle. With this
concept, this study adopted a simplified vehicle-bridge interaction model to present a semi-analytical solution of
dynamic response for a vehicle traveling on a simply supported beam, from which the vibration data of bridge
response was recorded in the instrumented vehicle. Then an experimental setup for measuring the bridge
frequency was introduced for verification of the indirect method. From the present experimental results, the
indirect bridge inspection method is applicable to monitor the dynamic characteristics of a bridge.Workplace Institute of Theoretical and Applied Mechanics Contact Kulawiecová Kateřina, kulawiecova@itam.cas.cz, Tel.: 225 443 285 Year of Publishing 2016
