The phenomenon of bridge vibration is a complex and uncertain occurrence that may be attributed to several factors, such as the dimensions and velocity of the vehicle traversing it, the uniformity of the bridge's surface, and the structural properties of the bridge. The main aim of this study is to use Finite Element Analysis (FEA) to examine the dynamic behavior of a bridge deck with a frame structure when exposed to vibrational loads. The computer-aided design (CAD) model of the bridge included I-shaped girders, using the ANSYS Design Modeler technology. The computer program ANSYS was used in the execution of the Finite Element Analysis (FEA) procedure. The occurrence of cracks inside the bridge deck resulted in a decrease in the inherent frequency of the deck, as well as an augmentation in the level of deformation it displayed.
