The infrastructure in Australia and beyond has long suffered from deterioration due to corrosion of steel reinforcement/sections. This project will address this problem by investigating a new form of hybrid columns, namely fibre reinforced polymer confined concrete-encased steel composite columns. The idea of combining a fibre reinforced polymer-confined concrete and a steel section not only makes the column a durable and ductile alternative to steel/concrete columns, but also makes them an efficient method for retrofitting or strengthening deteriorated steel columns. This project will study the structural behaviour of fibre reinforced polymer confined concrete-encased steel composite columns, and develop design methods to pave the way towards their wide practical applications.

由于钢筋/型材的腐蚀，澳大利亚及其他地区的基础设施长期以来一直在恶化。本计画将探讨一种新的混合柱形式，即纤维增强聚合物约束混凝土-外包钢组合柱。结合纤维增强聚合物约束混凝土和钢截面的想法不仅使柱成为钢/混凝土柱的耐用和延性的替代品，而且使它们成为改造或加固劣化钢柱的有效方法。本项目将研究纤维增强聚合物约束混凝土外包钢组合柱的结构性能，并开发设计方法，为其广泛的实际应用铺平道路。
