| Sumario: | [EN] Ultra High Performance Fibre-Reinforced Concrete (UHPFRC) is a very high performance stone building material, resulting from combining the three most advanced technologies used in concrete: heavy-duty, self-compactability and use of fibers. The first applications of UHPFRC in Spain for the construction of bridges are located in marine environments, because of its extraordinary durability of the material, as opposed to other conventional materials. This footbridges have a span length within a range of 20 to 40 m, and they are composed by trusses. However, the applicability of that structural system to more than 50 m span length turns out to be limited, therefore, it is necessary to look for new solutions. The purpose of this final project is to carry out the structural design of the superstructure of a footbridge of 60 m span length on the Cérvol river in Vinaroz (Castellón). In order to perform this project, high performance concrete ( UHPFRC ) is used, defining the manufacturing process of the different footbridge¿s elements and the final construction process. First, the current state of knowledge regarding the UHPFRC and its application in bridges and footbridges is studied. After that, a study of solutions is carried out to choose the optimal structural system to apply. As a result of the preliminary analysis, a tied-arch bridge is chosen as a natural evolution of the truss bridge. Following the solutions found in literature, it is decided that the footbridge is composed of modular elements connected by external prestressing and shear keys. After defining the solution, the structural analysis and design of the elements forming the superstructure of the footbridge is implemented. To carry out this section, it is necessary to develop a sectional calculation tool in order to adapt the design phase to the behavior of the material. As a result of this phase, axil - bending moment interaction diagrams can be obtained for designing sections under normal stresses. Subsequently, the manufacturing process of the different elements and the construction process of the footbridge is detailed. Finally, an economic assessment of the performance is done. |
