In 2017 and 2018 the Australian Standards for the design of concrete bridges and structures were released; these are some of the first in the world, to include design procedures for steel fibre reinforced concrete (SFRC) in a comprehensive way. While rules have been introduced for shear and bending of SFRC girders, the rules exclude the use fibres to carry torsional moments. This study investigates the torsion-bending-shear interaction performance of SFRC members. The study will provide vital data needed for for adoption by engineers and Standards bodies.

2017年和2018年发布了澳大利亚混凝土桥梁和结构设计标准；这些是世界上第一批全面纳入钢纤维增强混凝土（SFRC）设计程序的规范。虽然已经引入了关于SFRC梁的剪切和弯曲的规则，但规则排除了使用纤维来承载扭转力矩。本文研究了钢纤维混凝土构件的扭-弯-剪相互作用性能。这项研究将提供工程师和标准机构采用所需的重要数据。
