Application of composite steel and concrete bridge superstructures and particularly such with fully or partially encased steel girders in Republic of Bulgaria is discussed in the paper. It was chosen a particular bridge near Sofia with partially encased steel profiles built in 1994. It was elaborated a Finite Element Method (FEM) model, based on As Built drawings and side inspection of the current bridge. Project for field tests of the bridge was developed. Static and dynamic tests were performed by means of heavy truck vehicles. Results from the tests and the FEM models were compared and the models were calibrated. In conclusion the effectiveness of the bridge and load bearing capacity in accordance with present design standards are evaluated. |
