The comprehension of the authentic forces exerting influence upon a structure holds immense significance in the process of conducting condition assessments for existing structures. In this regard, this research presents a groundbreaking methodology for identifying dynamic moving forces acting upon a bridge structure. Its primary objective is to determine the optimal time-dependent force values that minimize the discrepancy between the computed and measured displacement and acceleration time histories at a limited number of sensor locations. Furthermore, the work encompasses extensive experimental investigations of the developed method on real structures in operation, which consistently demonstrate its efficacy across a diverse range of applications. These applications span from small structures subjected to relatively modest pedestrian forces to the substantial category of a complete train traversing a railway bridge. Additionally, this context provides an in-depth exploration of the specific nuances and constraints that arise when applying the method to real structures in practice.
