Several methods have been developed in recent years to identify moving loads on top of a continuous beam using measured vibration responses. The methods can identify the forces with some accuracy, but they have not been tested under field measurement conditions with a bridge-vehicle system. This pap

Identification of moving loads on bridges is an important inverse problem in the civil and structural engineering field. It is an effective way to better understand the interaction between the bridge and vehicles traversing it in order to achieve a satisfactory lifespan for the future bridge design.
Assumed mode shapes are often used to determine the responses of a bridge deck under the passage of moving loads. However, the use of these mode shapes in the inverse problem of force identi"cation would lead to unnecessary errors due to their inherent inaccuracy. Direct di!erentiation of the measur
