Prestressed I-beams made of ultra-high performance concrete for construction of railway bridges
Original language description
This paper focuses on research into prestressed I-beams made of ultra-high performance concrete, which are designed to be structural elements in small and medium span railway bridges. Prestressed concrete I-beams are designed with ten prestressing cablesin the bottom flange. The prestressed beams are laid close together in the actual structure with panels inserted between them. The entire structure will subsequently become monolithic. At the present time, I-beams made of rolled steel are commonly usedas structural elements in this type of structure. The advantage of these types of structures lies in their having a low construction height. This paper presents a computer and experimental analysis of the loading of UHPC prestressed I-beams. For the purpose of the experiments, three specimens of 7m span and two specimens of 12m span were made. The specimens were subsequently tested in the laboratory in four-point bending tests. The paper presents the process and results of the experiment
