The accurate safety assessment of structures is a fundamental requirement for their safe and cost effective design and management. In this respect, understanding the implications of geometric effects and physical instability on the failure behaviour of structures is a vital and challenging one. This project aims at achieving this by developing innovative approaches in which the classical, so-called, limit and shakedown, analyses are extended to incorporate these effects. The project will result in a significant advance in Australia's capability for enhanced diagnosis of its aging infrastructure and potentially also, through this newly developed computational ability, for the rapid transition of new materials to emerging technologies.

准确的结构安全评估是其安全和经济有效的设计和管理的基本要求。在这方面，理解几何效应和物理不稳定性对结构失效行为的影响是一个至关重要和具有挑战性的问题。该项目旨在通过开发创新方法来实现这一目标，在这些方法中，经典的所谓极限和安定分析被扩展到包括这些影响。该项目将大大提高澳大利亚对其老化基础设施的诊断能力，并可能通过这种新开发的计算能力，使新材料快速过渡到新兴技术。
