Development of ultra-high performance concrete columns against blasts

该项目旨在开发具有成本效益的超高性能纤维增强混凝土（UHPFRC）材料配方，该材料具有上级强度，延展性和耐久性，以取代关键基础设施中的传统混凝土。近年来，恐怖主义活动的威胁日益增加，突出了开发先进建筑材料以防止灾难性爆炸的必要性; UHPFRC是结构防护设计的理想选择。该项目计划开发一种混合设计方法，用于经济高效的UHPFRC材料。它还计划进行爆炸试验和数值调查，研究超高性能预应力混凝土柱的抗爆性，并制定在关键基础设施中应用这种柱的分析方法和设计方法。

This project aims to develop cost-effective formulae for ultra-high performance fibre reinforced concrete (UHPFRC) material with superior strength, ductility and durability to replace conventional concrete in critical infrastructures. In recent years, increasing threat from terrorism activities highlights the need to develop advanced building materials to protect against disastrous blasts; UHPFRC is an ideal option in structural protective design. This project plans to develop a mixed design approach for cost-effective UHPFRC material. It also plans to conduct blast tests and numerical investigations study blast resistance of UHPFRC columns and to develop analytical approaches and design methods for the application of such columns in critical infrastructure.
