Concrete arches and domes are prone to catastrophic failures which involve loss of life and limb, and many global iconic structures are of this form. When subjected to creep, shrinkage and thermal effects, their behaviour is non-linear and complex. This proposal will keep Australian research at the forefront by developing a fundamental understanding of these structural forms over time, when strengthened with externally-bonded composite materials in an innovative retrofit procedure. It encompasses the priority goal of frontier technologies for building and transforming Australian industry, will lead to valuable guidance for engineers, and will contribute to the training of skilled PhD scholars.

混凝土拱顶容易发生灾难性的破坏，造成生命和肢体的损失，许多全球标志性建筑都是这种形式。当受到蠕变、收缩和热效应时，它们的行为是非线性的和复杂的。这项建议将使澳大利亚的研究保持在前沿，随着时间的推移，通过在创新的翻新过程中使用外部粘结复合材料来加强对这些结构形式的基本理解，使澳大利亚的研究保持在领先地位。它包含了建设和改造澳大利亚工业的前沿技术的优先目标，将为工程师提供有价值的指导，并将有助于培训熟练的博士学者。
