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 design procedures for steel fibre reinforced concrete (SFRC) in a comprehensive way. While rules have been introduced for flexure and shear, strict limitations are placed on application where large plastic rotations are expected. This study investigates the moment-rotation performance of SFRC beam-column connections containing economical fibre dosages. The study is expected to provide data on the post-ultimate behaviour and robustness of SFRC moment hinges and determine moment-rotation relations for adoption by engineers and Standards bodies.

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，也是世界上第一个全面纳入钢纤维混凝土（SFRC）设计程序的标准。虽然已经引入了弯曲和剪切的规则，但对于预期有大塑性旋转的应用，仍有严格的限制。本文研究了含经济纤维用量的钢纤维混凝土梁柱节点的弯矩-转角性能。这项研究预计将提供数据的极限后的行为和鲁棒性的钢纤维混凝土力矩铰链，并确定力矩旋转关系，通过工程师和标准机构。
