The highway bridge is a simple supported 25 meter span bridge with two independent superstructures, one for each travel direction. One such superstructure consists of five prefabricated prestressed concrete girders that are I-shaped with a height of 1.4 meter, and a monolithic concrete bridge deck with thickness 0.24 meter. The bridge is located in Slovenia near the village of Vransko.

Object analysis
The assessment is performed in three steps incorporating different information gained by B-WIM measurements. An initial reference point was determined based on design codes for new structures. In step one, measured influence lines were incorporated and in step two, the model was calibrated to measured load distribution over the girders. The third step was to define and use a site specific load model. The reliability index increased significantly during the step-by-step assessment.
Object state
No deterioration processes or damages are reported. The aim of the case study is to demonstrate how a numerical model for a bridge can be calibrated using BWIM data in a step-by-step procedure.
