A very large part of Australia's dam, bridge and building infrastructure is ageing and experiencing cracking and deteriorations in material properties caused by progressive deterioration of concrete and corrosion of steel. This research addresses the practical and challenging problems of cracked structures with uncertainties in their properties and crack sizes. The advanced numerical tool developed as an outcome of this project will enable engineers to evaluate the reliability of structures under various scenarios of cracking, variation in material properties, rehabilitation and loading. The acquired knowledge will lead to more rational decisions in safe and cost-effective management of our ageing infrastructure.

澳大利亚大坝，桥梁和建筑基础设施的很大一部分正在老化，并且由于混凝土和钢的腐蚀而导致的材料特性的破裂和劣化。这项研究解决了破裂结构的实用和挑战性问题，其性质和裂纹大小不确定。作为该项目结果开发的高级数值工具将使工程师能够在各种裂纹，材料特性，康复和负载方面评估结构的可靠性。获得的知识将导致对我们老龄化基础设施的安全和成本效益的管理进行更合理的决策。
