In the frame of the research work APVT-20-012204, three reinforced concrete girder bridges were diagnosed. The results of the diagnostic will be used for modelling and investigation of the real traffic load effects. The modified reliability levels for the evaluation of existing bridges were used for their evalua- tion (Koteš 2005, Koteš & Vičan 2006). The different remaining bridge lifetimes for various load models given in the Slovak standard were obtained by calculation. Here, the paper is focused on just one bridge, which is the most corrupted. This bridge was numerically mod- eled using software ATENA. The material characteristics needed for modelling were obtained by diagnostic. The bridge should be strengthened due to low load-carrying capacity. The CFRP lamellas for strengthening of the girders subjected to bending will be used in the FEM model. The results of numerical analyses using the FEM model are used for the prepared experiment.
