The project aims to quantify the initial and long-term cracking and deformation of fibre reinforced concrete structures such as tunnel linings and slabs under sustained in-service loads and conditions. Concrete structures with and without conventional steel reinforcement and containing either steel or polypropylene fibres mixed in the concrete will be tested experimentally and modelled analytically and numerically. Expected outcomes are benchmark experimental data on structural behaviour under sustained loads, development of reliable simulation models and robust design procedures for the control of time-dependent cracking and deformation in fibre reinforced concrete, with reduced maintenance costs and more sustainable concrete structures.

该项目旨在量化纤维增强混凝土结构（如隧道衬砌和楼板）在持续使用荷载和条件下的初始和长期开裂和变形。混凝土结构与传统的钢筋和含有钢或聚丙烯纤维混合在混凝土中，将进行实验测试和建模分析和数值模拟。预期成果是关于持续荷载下结构行为的基准实验数据，开发可靠的模拟模型和稳健的设计程序，以控制纤维增强混凝土随时间变化的开裂和变形，降低维护成本，提高混凝土结构的可持续性。
