This thesis presents the design and static analysis of 55 m long railway bridge deck in Luka Koper. Analyzed construction is designed as four span integral concrete bridge with foundation consisting of 50 m long piles. Bridge deck is analyzed as composite cross section of four prefabricated post tensioned beams with in-situ concrete slab on them. For the analysis is made an idealized 3D mathematical model with Sofistik computer program based on finite element method. The interaction between soil and construction is also taken into account in the model with appropriate soil characteristics. In the analysis different effects were taken into consideration, such as permanent
impact, impact of prestressing, wind, temperature, traffic and impact of differential settlement of supports. Analysis of bridge deck is carried out during construction and in phase of use where creep and shrinkage development is also taken into consideration. All the necessary checks are done for serviceability limit state and ultimate limit state. In the appendixes are represented the situations and characteristic sections of bridge along with reinforcement drawing of bridge deck.
