Abstract:
This presentation delves into the finite element (FE) modelling of steel fibre-reinforced concrete (SFRC) and ultra-high-performance concrete (UHPC), materials known for their enhanced tensile strength and durability. The presentation focuses on identifying and addressing key challenges in accurately simulating the behaviour of SFRC and UHPC using FE analysis. Critical aspects such as fibre orientation, distribution, crack spacing, and crack width are explored, alongside the implications of these factors on overall structural performance. The presentation also evaluates the influence of various modelling approaches and material parameters on the accuracy and reliability of the simulations, including modelling for localisation. By highlighting best practices and common pitfalls, the presentation aims to provide valuable insights for engineers and researchers involved in the computational modelling of structures containing these novel materials. The findings will contribute to more robust and reliable designs in structural applications where SFRC and UHPC are utilised, ensuring safety and performance in real-world scenarios.
