Non-deterministic fracture analysis of structures by extending the scaled boundary finite-element method

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.
