Characterisation of shear and tensile fracture of ultra-high performance fibre reinforced concrete

本课题旨在研究超高性能纤维混凝土（UHPFRC）的剪拉交互作用性能。2014年1月，澳大利亚发布了混凝土桥梁设计标准草案;这是澳大利亚第一个标准，也是世界上第一个包括钢纤维混凝土（SFRC）综合设计程序的标准之一。规则允许常规的应变软化SFRC，但排除了应变硬化UHPFRC的使用，因为常规加固时对材料的核心方面的研究不足。该研究预计将提供重要的数据工程师和标准机构需要采用UHPFRC。

This project aims to investigate the shear-tension interaction performance of ultra-high performance fibre reinforced concrete (UHPFRC). In January 2014, the draft Australian Standard for the design of concrete bridges was released; this is the first standard in Australia, and one of the first in the world, to include comprehensive design procedures for steel fibre reinforced concrete (SFRC). Rules allow conventional, strain softening SFRC, but exclude the use of strain hardening UHPFRC because of insufficient research on core aspects of the materials when conventionally reinforced. The study expects to provide vital data engineers and Standards bodies need to adopt UHPFRC.
