Bridges require continuous screening to ensure their structural integrity. Recently, authors have studied the feasibility of using measurements from a truck equipped with sensors to determine the damage level in the structure of the bridge. This technique is known as “Drive-by Bridge Inspection”. Most of research conducted in this area focused on the processing of the recorded signal to extract the bridge modal properties. This paper presents an alternative method of using the truck measurements to calculate the change in the bridge deformation due to structural damages instead of investigating the bridge modal values. The study uses the Inverse Dynamics Optimization Algorithm to calculate the change in the bridge displacement. A half car model with four degrees of freedom is used to represent the inspection truck. The solution for the Vehicle Bridge Interaction (VBI) is done using the LS-Dyna FEA program. A road roughness class ‘A’ is used to represent the road roughness heights.
