Title: | Anisotropic tensile behaviour of UHPFRC: meso-scale model and experimental validation |
Issue Date: | 2019 |
Abstract: | Ultra-High Performance Fibre-Reinforced cementitious Composites (UHPFRC) designates a family of materials constituted by a compact cementitious matrix reinforced with short high-strength steel fibres. A model is presented based on a meso-level description of the involved mechanics for simulating the direction-dependent tensile response of the UHPFRC. The determination of the relevant material properties and model parameters is discussed. The model is validated with a set of direct tensile tests performed on specimens with varying fibre content and orientation and is shown to be capable of simulating the full tensile responses of both strainsoftening and strain-hardening UHPFRCs. Finally, an outlook is given on how the meso-mechanical model can be used to provide the input parameters for the engineering stress-deformation curves describing the anisotropic tensile behaviour of the material and that are suitable for analysis and design of UHPFRC structures. |
