This European research project has been funded by the EU Research Fund for Coal and Steel
Steel-concrete composite bridges are an important alternative to concrete bridges due to considerable advantages regarding the design, construction time, durability and costs. They are largely exploited in high-speed lines of the European railway networks even if a lot of still open problems in design and management limit their exploiting. The project aims to remove actual uncertainties on dynamic effects and interaction phenomena, fatigue loadings, structural modeling, fatigue life and damage assessment. What's more, such results will allow to set up an innovative design approach, able to minimize life-cycle costs guaranteeing adequate safety level and working conditions.
