摘要：The system identification can be defined as the process of deducting and/or updating the structural parameters relating to the dynamic data recorded through specific measurements. The structural parameters used mainly in the case of bridge structural behaviour are flexural rigidity, damping and modal parameters. The analysis of any change in these parameters helps the administrators permanently monitor the technical status of the bridge. In Romania the use of identification systems in the technical monitoring of bridges has three main advantages. First, the optimized management of the limited financial resources allocated to the maintenance and repair of the bridges is desired. Secondly, the operating life of the structure under normal conditions is extended due to the optimization of the maintenance and repair works. Finally, the fluidization of the traffic and the elimination of the waiting times that occur as a result of the rehabilitation works may be achieved by carrying out the repairs in time.
